Octarine Core Effect For Best Hero

Added to the game in Patch 6.84, the Octarine Core is an item that caused quite an uproar at the time of the update, as brought two new mechanics to Dota 2: Cooldown Reduction and Lifesteal by Spells (Spell Lifesteal); mechanical ones that are quite common there in the League of Legends. The item is in the category Magic in Store and can be purchased directly in the Secret Shop, because all items are sold there the form. It is also one of the most expensive game, tying with Satanic (Satanic) and losing only the Divine rapier (Divine Rapier, 6200) and the Abyssal Blade (Abyssal Blade, 6750 Gold). Let's take a look at the attributes of the first item:

Octarine_Core "In sorcery center are spectra that only the most talented can perceive."

Price: 5900

Soul Booster (3200)

Point Booster (1200)

Energy Booster (900)

Vitality Booster (1100)

Mystic Staff (2700)

status:

+25 Intelligence

+450 HP

+400 Mana

+4 HP Regeneration

+ 100% Mana Regeneration

As the item gives 25 Intelligence, the total amount of Mana he ensures is 725 (400 + 325 INT, the largest of the game), and +1.0 mana regeneration. If a hero with intelligence as the primary attribute ensures +25 damage. But in addition, it ensures the item two passive skills that guarantees no other items (they do not accumulate!). they are:

Range reduction between uses (Cooldown Reduction):

Decreases the use of range of all items and spells by 25%.

Comments:

Reduces the cooldown of items and assets and liabilities spells.

Invisibility does not affect Permanent (Permanent Invisibility) Riki , Brewmaster.

It does not diminish the recharge time of spells that work through loads (as reminders of Fire [Fire Remnant] Ember Spirit, for example).

Decreases replenishing interval timeGuardian Greaves

Magic Life Steal (Spell Lifesteal):

A percentage of the damage caused by user skills back to the user as life. Heroes: 25%; creeps in: 5%.

Comments:

Healing from any injury that causes user (except basic attack) against enemies or allies after all the damage reduction.

Illusions are affected by Lifesteal if they have some way to use it (as Radiance).

Affects most passive skills and causing damage, are items or skills; modifying effects except for some attack, such as anti-aircraft gun (Flak Cannon) of Gyrocopter, for example.

No cure from attacks on structures (towers), wards or in itself.

Healing affects all three types of damage (Physical, Magical and Pure) and effects that kill instantly also Culling Blade the Axe, for example).

For healing to happen, the source of damage should be the user; therefore there is no cure when the damage comes from invoked units (including Wards) by the user (Death Ward) the Witch Doctor, for example).

visual effect on the character when he uses a spell that ensures Lifesteal with octarine.

Now that the item already explained, the question that remains is:

Which heroes he's really good and when I build?

This is quite simple; but there are two points that you must understand: First, the heroes buildam the octarine because it reduces the cooldown of the items / skills. Simple like that. The Lifesteal for spells is the icing on the cake just a bonus. Second, the octarine core is not required of anyone mentioned below, only a good option. Last but not least: The octarine is an item of lategame except for some very few heroes. For several of the heroes in the list below it is very good, but you will hardly be able to Farma it as you will need the most important items before and his farm position may not help. Knowing this, there are some categories that fit the heroes who build the core octarine, they are:

They need High Mana Regeneration:

Heroes usually need a lot of mana regeneration is because they need to maintain an ability to spend mana per second active, or use some spells constantly on the battlefield. As they need to be alive - of course - to cast these spells, high HP and Lifesteal Spells to fall very well with these heroes. Heroes marked in this category are those that best use octarine Center.

Has Skills Cooldown Very High:

Here come those heroes with powerful abilities, usually their ultimates, which are able to change the course of a teamfight or even a game is launched correctly, but these skills usually have a high range of use. It is easy to identify them; They are usually the heroes that cause enough impact on teamfights with their skills. Most of them, however, makes better use of (Refresher Orb), and only build octarine after Orbe, except some cases. The other attributes guaranteed by item usually go well for most of the heroes in this category, while the Lifesteal ranges from hero to hero.

Abuse Effects with Reduced Cooldown:

The heroes who come here are kind of mixed the above categories: spend mana fairly and have strong skills with a reasonable cooldown. With the reduced cooldown, they can best use your skills to cause more damage to opponents, as this reduces the factor "uptime" of their skills; ie how long it takes for the effect of an ability to be applied again with respect to cooldown. For example, for the ultimate from Ancient Apparation, which has 40 seconds cooldown, their uptime when it has Aghanim's Scepter is 23 seconds, because the effect lasts ultimate 17 seconds (uptime is calculated cooldown - duration of effect); with octarine this value fell to 13 seconds.

Heroes and octarine:

Now yes, we go to the table with the item's why the explanation be good at it and at what time of the game to build it. Consider:

Heroes table

Ancient Apparition

The octarine core can be a good option for the AA after Aghanim. Reducing from 40 to 30 seconds the ultimate cooldown and allowing it to regenerate from his injury (including breaks!) Makes him a hero even more annoying to deal with. It combines well with Shiva Protection (Shiva's Guard) and the Scythe of Vyse (Scythe of Vyse), two items that AA usually do and have high cooldown.

Category (s): 3.

Alchemist

In the style Naga Siren, the octarine Core is an option for the Alchemist in the build Radiance + Manta Style, which became more popular after the departure of the Alliance against NiP, 2 set by the European Qualifying for Major Frankfurt. With the three items, the Alliance held the mega creeps opponents and won the game in impressive fashion. The Alchemist, the item works well because it gives you a lot of HP and mana and most importantly, reduces the ultimate use range in 12:25 seconds, which is very good, since without the ultimate it is a pretty mediocre hero. However, octarine only works well as an item that you get after doing a couple, three major items, since it does not improve the Alchemist farm directly nor improves their teamfight (the lifesteal is virtually useless to him if you do not have a Radiance). Important that the cooldown reduction in Manta Style and Abyssal Blade are also great for him.

Category (s): 3.

Chaos Knight

The main use here is the reduction (absurd) the ultimate cooldown Phantom (Phantasm), reducing from 140 to 105 seconds interval. As your illusions do great damage (they are the most powerful of the game) can more often use them gives you a great advantage. Item attributes also increase the durability of illusions, but lifesteal is virtually useless to him.

Category (s): 2, 3.

Crystal Maiden

The octarine is a very powerful item in Crystal, the problem is Farma it. You will hardly be able to get to do it, unless the match pass an hour. Not only because Crystal is support, but because it needs a number of other items before; BKB, Blink, Force and sometimes a Scythe of Vyse. If game conditions present themselves conducive to the construction of the item, do so; but remember the other items already mentioned, which help much to Crystal.

Category (s): 2, 3.

Dark Seer

With two very powerful magic and with high cooldown;  (Vacuum) and Wall of Replica), Dark Seer is a hero who does well in his service teamfights, putting unsuspecting enemies in bad position. The lifesteal razoalvemente is useful for him because of Shell Ion (Ion Shell), which causes high damage, but the main thing is always to reduce the use of time.

Category (s): 2, 3.

Death Prophet

The Death Prophet is one of the best users of octarine; reducing the cooldown of your skills makes it even more dangerous and its ultimate gets even better with Lifesteal too. I recommend close the item at least after some other first (Eul's Scepter, Bloodstone, for example); overall it is a great item for her.

Category (s): 1, 2, 3.

Doom

Doom makes excellent use of cooldown reduction; all spells have high range of use. It combines very well with the Orb Restorer too, as it reduces the item usage range as well. The item goes well after any item that gives enough armor for Doom; since high physical damage is excellent against him.

Category (s): 2.

Earthshaker

The Earthshaker is one of those cases where the octarine is a good item, the problem is Farma it. And just as other media quoted here, he needs before other items: an item that gives mana and a Blink Dagger. I just do it as the last item; but the game would have to be very long for that to happen.

Category (s): 2, 3.

Elder Titan

Elder Titan is a hero that has great potential, but relies heavily on the heroes around and coordination of its partners. His to farm capacity is not the best and therefore the octarine is like a luxury item in it. The reduction in cooldown of Astral and  Echoing Spirit help a lot, but the highlight is right for your ultimate and for any asset item he builds like a Sickle Vyse.

Category (s): 2, 3.

Enigma

The octarine is an excellent item in the enigma not only because he has a skill with a very high cooldown (Black Hole, with a total of 200/190/180 seconds), but because his other skills also have a large usage range (your ability cooldown is less  Malefice, 15 seconds). Not to mention the damage caused by Midnight Pulse is high and the lifesteal helps a little. The octarine is a good option after Blink / BKB, depending on the pitch, but you will usually need other items before as a Shiva Protection or Sickle Vyse.

Category (s): 2.

Huskar

While Huskar not need ridiculous amount of mana that octarine gives the ability he has to cause magic damage makes it very useful lifesteal, and cooldown reduction helps a lot depending on the active items you have on hand, especially if it one Satanic  or BKB.

Category (s): 3.

Invoker

The octarine is an amazing item to Invoker because the cooldown reduction affects all your 11 skills (+ Invoking the 10 skills that he can summon). Like all skills he can invoke have a cooldown between 15 seconds and 55 seconds reduced considerably decreases uses them apart. The Lifesteal also helps you stay alive in teamfights, since his skills are capable of causing high damage. I recommend buying the octarine only after the Scepter of Aghanim.

Category (s): 2, 3.

io

Again the story of support that fails to farm. The octarine is expensive absurdly for a hero who is struggling to get a Urn of Shadows , but quite powerful by the reduction in cooldown to relocate and the regeneration of both HP and Mana, which can be passed to an ally through Tether. The amount of health and mana still Io help to stay alive, as is the hero is quite fragile.

Category (s): 2.

Leshrac

The Leshrac was one of the first heroes to be used in position 1 farm (carry) because it was able to cause high magic damage. The arrival of the just octarine core cooperating to establish itself in this Leshrac poisção, since the Lifesteal is quite remarkable in a hero 4 skills that cause damage, especially when the cooldown of them is even smaller. The item is very good as third or fourth item build, usually after a Shiva Protection.

Category (s): 1.

Lina

Lina is a heroine capable of causing high damage of any kind: Magic through their skills, physical when his passive is with loads and pure with its ultimate + Sceptre Aghanim. The octarine nucleus ensures that it always has mana to cast their spells, not to mention the cooldown reduction facilitates the accumulation of charges of passive Burning Soul (Fiery Soul), coupled with Lifesteal core. Good item after Aghanim.

Category (s): 1, 3. https://dota2-indonesia.blogspot.com

Naga Siren

The Naga has become one of the best users of octarine Center because the item further enhances the ability to wear down the enemy. Illusions Radiance (and Lifesteal!) In all lanes, 30 to 30 seconds without stopping, it is very annoying to deal with. Teamfights force to defeat it is even more difficult, since Song of Mermaid (Song of the Siren) is 45 seconds cooldown after reduction. Item mandatory after Radiance.

Category (s): 3.

Nature's Prophet

The octarine is only useful in Furion if you build a Aghanim for him; thus allowing him to create Treants all over the map, 45 in 45 seconds, without having to put at risk. The reduction in cooldown (Teleportation) and Nature's Call  is also very useful, also accounting for the items you might need, like  (Orchid Malevolence), Scythe of Vyse or any other with acting ability.

Category (s): 3.

Necrophos

With the ability to temporarily ban a game hero with his ultimate + Aghanim, have the ability to do this every 52 seconds instead of every 70 seconds it is very important (as long as you kill your target, of course). The high amount of mana given by octarine lets you use  (Death Pulse) where available, which is very important for Necrophos.

Category (s): 2.

Night Stalker

View Night Stalker this list may seem strange, but the octarine Core can be great for him at the end of the game. The octarine reduces the ultimate use of the range it for 60 seconds at the last level; wherein the duration of the night prev is 50 seconds or you increases so does the amount of night time to departure. Remember that the ultimate of the Night Stalker does not pause over the day / night cycle, but overlaps the time, ie, it is best to use your ultimate while day.

Category (s): 2.

Nyx Assassin

Even if Nyx will be able to improve your skills significantly through Burrow (Burrow) ability given by Scepter Aghanim the cooldown reduction in Impale  and Mana Burn  allows Nyx increases its presence further in teamfights, becoming even more annoying problem for opponents.

Category (s): 3.

Omniknight

The Omniknight already enters the case of spells with very high cooldown. His ultimate, Guardian Angel  changes the direction of teamfights when released at the right time; take that chance every 112.5 seconds (instead of 150) is fantastic. The reduction is also very good for Repel , since the effect can be kept constant, as the cooldown drops to 10.5 seconds; while the effect lasts for 12 seconds at maximum level.

Category (s): 2.

Outworld Devourer

Even if the Outworld Devourer has no problem with mana since it has (Essence Aura) and can still steal intelligence of opponents through Astral Prison (Astral Imprisonment), the Lifesteal pure damage  (Arcane Orb) with an increase in the very high damage (since octarine gives over 725 mana to play Harbinger), they are too good to pass up. I recommend the item as the third or later to be closed.

Category (s): 1, 3.

puck

Even if / Puck is not a hero who has difficulties to farm their items in octarine, even if very efficient for him / her (whatever) it's hard to fit in the build because the / Puck need a number of other items. Shiva protection, Sceptre Aghanim, BKB, Scythe of Vyse, Scepter Divine Eul, Force Staff, are all excellent choices, not counting the boots and Blink Dagger. The item is best choice when you are in advantage over the opponent, since the reduction in cooldown of the items / skills will make him / her puck even more annoying to deal with.

Category (s): 2, 3.

Queen of Pain

The Queen of Pain is a heroine who rises and the team's ability to exercise control and pressure around the map. With their high damage spells (Magic / pure) and a decent basic attack, octarine Center substantially reduces the cooldown of his ultimate (if you do not have Aghanim) and allows the Queen of Pain make your work easier still. It is a good option as the fifth or last item in the build.

Category (s): 2, 3.

Rubick

The octarine for Rubick is quite situational, after all, you will depend on the skills of their opponents to take advantage it better, since spending 5900 gold just to reduce the cooldown of your Stun 6 seconds and the ultimate (if you have Aghanim) for 12 seconds, is not the best investments. If the opposing team includes several of the heroes mentioned here in the list, it can be a very useful item.

Category (s): 2.

Sand King

Unlike most media, the Sand King has no difficulty to farm their items. The octarine greatly reduces the cooldown of your powerful ultimate, epicenter , and the Blink and any other item that you build. It can be a very useful item in late-game.

Category (s): 2, 3.

Skywrath Mage

I was a little reluctant to put Skywrath here in the list as there are octarine has virtually the same amount of points against compared to favoring the item in it. First, your skills already have extremely low cooldown; with the same Aghanim, the ultimate cooldown is zero! However, their skills can cause high magic damage, and lifesteal would be very useful to him. Another point is in favor is that Skywrath skills require a lot of mana, and octarine is the item that most gives mana in the game - but the Skywrath will hardly be able to farm the item, its parts are very expensive separate and other items as Protection Shiva or Scythe of Vyse may be more useful to him and the team. If I were to buy it it just would after any of those other items mentioned.

Category (s): 3.

Silencer

The octarine serves very well for Silencer cause even more damage on opponents, substantially increasing the damage glaives of Wisdom (glaives of Wisdom) because, besides guaranteeing the lifesteal by pure damage. The reduction from 130 to 97.5 in the ultimate cooldown helps a lot, because it always changes the course of a teamfight when released at the right time.

Category (s): 2.

Tidehunter

The Tidehunter is another one of those heroes who buy octarine together with Refresher Orb and thus take advantage of the powerful Ravage, your ultimate. The core attributes combine well with the items that Tidehunter builds (not vary much the same) as the Shiva Protection.

Category (s): 2.

venomancer

One of the most boring heroes to face in the game, the Venomancer is even more annoying if it can achieve even more with your opponents slows. All your skills benefit from the cooldown reduction, beyond lifesteal, which allowed the Venomancer lasts a little more in teamfights. The octarine is a good option after the Scepter of Aghanim.

Category (s): 2, 3.

Warlock

The most common build the Warlock aims to rush Aghanim and Refresher in order to stun enemies twice and invoke 4 golems. Others choose to buy more general items that may also benefit the companions, as Veil of Discord (Veil of Discord) or Shiva Protection. Whatever you build it, the octarine is a good option for lategame because his ability is high cooldown, and spend enough mana.

Category (s): 2, 3.

Winter Wyvern

The four skills of Wyvern, 3 of them did not decay throughout the game (the exception is shattering explosion [Splinter Blast], because it causes permanent damage). Having the cooldown reduction in three spells that are excellent throughout the game is fantastic. The funny thing is that just the ability that less benefits from bonus octarine that facilitates Wyvern's ability to farm the item. I recommend after a Scythe of Vyse.

Category (s): 2, 3.

Zeus

Zeus is another one of those heroes who make excellent use of Spell Lifesteal ally with a high mana regeneration. The constant use of  (Arc Lightning) causes Static Field  is activated several times, and in late-game, passive Zeus is what he does best for teamfights in terms of damage. The item goes well if you like to build Refresher it, but it is very useful without the Orb as well.

Category (s): 1, 3.

Conclusion:

When it was released in patch 6.84, the octarine caused quite a stir among the players for bringing the game two new mechanics that are quite famous there in the League of Legends, most Dota2 rival in MOBAS scenario. Many claimed that the item would be "much stolen" in certain heroes, especially those who make heavy use of magic damage. However, none of these expectations are confirmed: the octarine is a very expensive item, and their training does not help much, after all, the amplifier (Energy Booster), which is the cheapest of the item costs 900 gold. Moreover, Lifesteal in the magic is hardly a major factor for heroes of the game, very few are those who can make use of it true. Investment in octarine within the game it just gives by reducing the cooldowns of items and skills, as spoken so often, after all, you lay the game a hero through the spells he has. The more often you can use them, the better. The construction of octarine Core requires good reading of the game conditions - your hero will have more room to do what makes the reduction cooldown? The attributes of octarine help how? Pay attention to this and always keep in mind that passive item may not be as useful as any item that gives some skill as a Shiva Protection, Force Staff or Lotus Orb.
