2. Common Talent Paths

2.1. Flamestrike Build (talent calculator link)

The Flamestrike Build focuses on bolstering the damage output and utility of Flamestrike, providing Kael'thas with even stronger AoE damage. It is important for Kael'thas to try to complete the quest portion of Convection Icon Convection as early as possible, as the reward will grant a massive power spike to Flamestrike. Enemy teams will often try to focus Kael'thas down before he is able to finish his Convection quest, so be sure to play cautiously until it is completed. Empowering Flamestrike with Verdant Spheres Icon Verdant Spheres will make it much easier for players to strike multiple enemy Heroes, making great use of both Burned Flesh Icon Burned Flesh and Flamethrower Icon Flamethrower.

2.2. Living Bombs Build (talent calculator link)

The Living Bombs Build is an effective alternative to the Flamestrike Build, primarily when Kael'thas may find himself having a hard time landing casts of Flamestrike on his targets. The "targeted" component to Living Bombs makes it much easier to guarantee damage, especially against teams with multiple highly mobile targets that are difficult to hit with Flamestrike. Kael'thas will need to play cautiously with a strong awareness of his positioning since the cast range of Living Bombs is somewhat limited. Try to cast Living Bombs on targets of high priority (when possible), but do not be afraid to cast in onto the enemy frontline as, many times, they may carry the explosion back into their own team, further spreading the bombs.

3. Level 1 Talents

Kael'thas Convection
Convection (Level 1) World of Warcraft Kael'thas

Quest: Damaging an enemy Hero with Flamestrike increase its damage by 5, up to 100. This bonus is lost on death.

Reward: After hitting 20 enemy Heroes, increase Flamestrike damage by an additional 100 and no longer lose any bonuses on death.

Kael'thas Fel Infusion
Fel Infusion (Level 1) World of Warcraft Kael'thas

Increases Kael'thas's Spell Power by 4%. Kael'thas heals for 94 (+4% per level) Health when activating Verdant Spheres.

Kael'thas Mana Addict ?
Mana Addict (Level 1) World of Warcraft Kael'thas

Quest: Gathering a Regeneration Globe increases Kael'thas's maximum Mana by 15.

Reward: After gathering 20 Globes, Kael'thas can activate Arcane Barrier to gain a Shield equal to 100% of his maximum Mana for 4 seconds. 45 second cooldown.

3.1. Discussion

Convection Icon Convection, when fully stacked, can be an incredibly strong talent option. The high-risk, high-reward nature of Convection makes it a challenging, yet rewarding choice. The massive increase in damage to Flamestrike Icon Flamestrike is monumental in a Flamestrike-centric build. It is very important to play safe when trying to complete the quest portion of Convection, as Kael'thas will lose all progress should he be killed before it is accomplished. This requires players to have to weigh the cost of overextending to aim and land a cast of Flamestrike. During the early game, particularly when in lane, make sure to keep an eye on the Minimap for missing enemies who may be attempting to gank Kael'thas. Convection works best with a strong frontline that will help peel away enemy Heroes from Kael'thas as he casts Flamestrike.

Fel Infusion Icon Fel Infusion is a great talent that provides Kael'thas not only with an overall increase in damage but also some nice passive healing. The self-sustain provided by Fel Infusion will help Kael'thas trade more efficiently in lane as well as during teamfights and skirmishes. This talent is a great option for players who want to increase their damage output but find themselves having a hard time effectively stacking Convection Icon Convection, particularly against assassins like Nova and Zeratul who will consistently attempt to hunt down Kael'thas before he can finish his quest.

Mana Addict Icon Mana Addict is a great source of damage mitigation and Mana regeneration for Kael'thas players who are willing to sacrifice raw damage output for sustain and survivability. Mana Addict might be the best talent option for Kael'thas when matched against a burst composition, as the large shield can help keep him up during the enemies focus fire, especially in the late game. The increased Mana pool will also help players last longer when trading over Objectives or sieging enemy fortifications. The bonus Mana granted after gathering a Regeneration Globe is immediate, and can be seen as an additional source of Mana regeneration.

4. Level 4 Talents

Kael'thas Nether Wind
Nether Wind (Level 4) World of Warcraft Kael'thas

Increases Gravity Lapse's range by 30%. When Gravity Lapse hits an enemy Hero, refund 80 Mana.

Kael'thas Energy Roil
Energy Roil (Level 4) World of Warcraft Kael'thas

When Gravity Lapse hits a Hero, reduce its cooldown by 9 seconds.

Kael'thas Mana Tap ?
Mana Tap (Level 4) World of Warcraft Kael'thas

Activating Verdant Spheres restores 4% of Kael'thas's maximum Mana.

4.1. Discussion

Nether Wind Icon Nether Wind is a great talent that increases the utility of Gravity Lapse Icon Gravity Lapse twice over. The increase in range will allow Kael'thas to more safely catch-out enemies or peel for allies. Nether Wind is incredibly strong when combined with Verdant Spheres Icon Verdant Spheres, as it will allow Kael'thas to land Gravity Lapse on Heroes hidden behind the enemy frontline. The Mana refund is also a great bonus that will help to somewhat relieve Kael'thas from the burden of his Mana intensive abilities.

Mana Tap Icon Mana Tap lacks the utility bonus of Nether Wind Icon Nether Wind, but is strong in that it is a reliable source of Mana regeneration. Unlike the Mana refund of Nether Wind, the Mana from Mana Tap is not dependent on landing an ability. Mana Tap also becomes all the more useful when talenting into Twin Spheres Icon Twin Spheres at Level 16.

Energy Roil Icon Energy Roil is unfortunately too weak of a talent option to justify its selection when compared to both Nether Wind Icon Nether Wind and Mana Tap Icon Mana Tap. The bonus cooldown reduction is only granted upon a successful cast of Gravity Lapse Icon Gravity Lapse, just like the Mana refund of Netherwind. The increase in cast range and the Mana refund of Nether Wind is much more rewarding to Kael'thas than a moderate reduction in cooldown of Gravity Lapse.

5. Level 7 Talents

Kael'thas Burned Flesh
Burned Flesh (Level 7) World of Warcraft Kael'thas

When Flamestrike damages 2 or more Heroes, they take additional damage equal to 8% of their maximum Health.

Kael'thas Sun King's Fury
Sun King's Fury (Level 7) World of Warcraft Kael'thas

Living Bombs that spread to enemy Heroes deal 35% more damage.

Kael'thas Sunfire Enchantment
Sunfire Enchantment (Level 7) World of Warcraft Kael'thas

Activating Verdant Spheres causes Kael'thas's next Basic Attack to instead deal 165 (+4% per level) Spell Damage.

5.1. Discussion

Burned Flesh Icon Burned Flesh will do massive amounts of damage to the enemy team should a cast of Flamestrike Icon Flamestrike land on multiple enemies. This talent will wreak absolute havoc on teams when combined with a quest completed Convection Icon Convection and Fury of the Sunwell Icon Fury of the Sunwell. Make sure to always cast an empowered version of Flamestrike using Verdant Spheres Icon Verdant Spheres in order to greatly increase the size of the ability and help ensure multiple enemies will be struck.

Sun King's Fury Icon Sun King's Fury will cause Living Bomb Icon Living Bomb to do large amounts of AoE damage to enemies unable to spread out after being struck. This talent is a great choice for the Verdant Spheres Build, where there is much less emphasis on the need to land casts of Flamestrike Icon Flamestrike.

Sunfire Enchantment Icon Sunfire Enchantment does not have the raw team wide damage output needed to be considered a viable pick. Although the single target damage bonus is actually not that bad, both Burned Flesh Icon Burned Flesh and Sun King's Fury Icon Sun King's Fury have a much stronger impact on teamfights and unfortunately cannot be passed up.

6. Level 10 Talents

Kael'thas Phoenix
Phoenix (Level 10) World of Warcraft Kael'thas
  • Mana: 80
  • Cooldown: 60 seconds

Launch a Phoenix to an area, dealing 78 (+4% per level) damage to enemies along the way. The Phoenix persists for 7 seconds, attacking enemies for 78 (+4% per level) damage and splashing for 50%.

Kael'thas Pyroblast ?
Pyroblast (Level 10) World of Warcraft Kael'thas
  • Mana: 80
  • Cooldown: 100 seconds

After 1.5 seconds, cast a slow-moving fireball that deals 810 (+5% per level) damage to an enemy Hero and 405 (+5% per level) damage to enemies nearby.

6.1. Discussion

Phoenix Icon Phoenix is a great reliable source of damage that should be the standard pick for the vast majority of matches. There are a multitude of uses for Phoenix, such as zoning, waveclearing, and sieging or defending fortifications. Unfortunately Phoenix lacks any sort of crowd control, so many times enemies will be able to easily walk out of its effect. That is why Phoenix is best used in conjunction with reliable sources of crowd control. The abilities listed below are often used in conjunction with Phoenix.

The 60-second cooldown of Phoenix further makes it a great ability. The relatively short cooldown of Phoenix can help guarantee that it will be available for most teamfights or skirmishes, particularly those surrounding importan: Battleground objectives.

Pyroblast Icon Pyroblast is hands down the most powerful single-target ability in the game. Pyroblast can be used to finish off most targets, particularly squishier enemies such as supports or assassins. Alas, Pyroblast is the definition of situational, as it is incredibly unreliable and difficult to channel. The 1.5-second channeling time puts Kael'thas in an incredibly vulnerable position. Most enemies, especially those with a source of interupt or burst damage, will attempt to capitalize on Kael'thas' exposure. Even if Kael'thas is able to successfully cast Pyroblast, the slow movement speed of its projectile will give enemies ample time to react. There are many ways the damage of Pyroblast can be completely negated, such as by Uther's Divine Shield Icon Divine Shield or Tyrael's Sanctification Icon Sanctification. Pyroblast should never been taken should the enemy team have a means to counter it.

7. Level 13 Talents

Kael'thas Pyromaniac
Pyromaniac (Level 13) World of Warcraft Kael'thas

Each time Living Bomb deals periodic damage, Kael'thas's Basic Ability cooldowns are reduced by 1 second.

Kael'thas Backdraft
Backdraft (Level 13) World of Warcraft Kael'thas

Living Bomb's explosion slows enemy Movement Speed by 30% for 2 seconds.

Kael'thas Fission Bomb
Fission Bomb (Level 13) World of Warcraft Kael'thas

Increases Living Bomb's explosion radius by 20%.

7.1. Discussion

Pyromaniac Icon Pyromaniac is a great choice when trying to maximize Kael'thas' damage output. The reduction in cooldown for Kael'thas' Basic Abilities will greatly increase his damage uptime. Also, the reduction in cooldown of Gravity Lapse Icon Gravity Lapse will provide Kael'thas with additional utility allowing him to be more useful in teamfights and skirmishes.

Backdraft Icon Backdraft provides a nice element of crowd control to Living Bomb Icon Living Bomb. This slow is quite significant and makes it easier for Kael'thas to land his other abilities. Enemies under the effect of Backdraft will also have a much more difficult time trying to escape the AoE damage of Phoenix Icon Phoenix. When confronted by melee Heroes, the slow provided by Backdraft will assist Kael'thas in kiting them.

Fission Bomb Icon Fission Bomb is useful in terms of increasing the area-of-effect zone of Living Bomb Icon Living Bomb, however the utility of both Pyromaniac Icon Pyromaniac and Backdraft Icon Backdraft must be sacrificed for it. The 20% increase in explosion radius may feel underwhelming, leaving Fission Bomb better left unpicked.

8. Level 16 Talents

Kael'thas Fury of the Sunwell
Fury of the Sunwell (Level 16) World of Warcraft Kael'thas

Flamestrike will explode a second time 1.5 seconds later.

Kael'thas Twin Spheres
Twin Spheres (Level 16) World of Warcraft Kael'thas

Verdant Spheres gains a second charge.

Kael'thas Arcane Dynamo
Arcane Dynamo (Level 16) World of Warcraft Kael'thas

Using a Basic Ability increases Kael'thas's Spell Power by 3% for 5 seconds, stacking up to 15%.

8.1. Discussion

Fury of the Sunwell Icon Fury of the Sunwell is incredibly strong and a must pick for the Flamestrike Build. The strongest feature of Fury of the Sunwell is that the second cast of Flamestrike Icon Flamestrike inherits all of the original cast's talent related bonuses. This means both Convection Icon Convection and Burned Flesh Icon Burned Flesh will be included in the second explosion, allowing a single cast of Flamestrike to do absolutely devastating amounts of damage to the enemy team.

Twin Spheres Icon Twin Spheres is a great choice for players who build more around the effects of Verdant Spheres Icon Verdant Spheres than Flamestrike Icon Flamestrike. The second charge of Verdant Spheres provided by Twin Spheres acts just like the original, activating any and all talent bonuses surrounding it. This means that Fel Infusion Icon Fel Infusion, Mana Tap Icon Mana Tap, and Sunfire Enchantment Icon Sunfire Enchantment all become effectively twice as beneficial should they have been previously selected for.

Arcane Dynamo Icon Arcane Dynamo at first appears to be a tempting option to increase Kael'thas damage output. Unfortunately in practice it feels rather weak, especially when compared to Fury of the Sunwell Icon Fury of the Sunwell and Twin Spheres Icon Twin Spheres. Because the effects of Arcane Dynamo only last for 5 seconds, unless having already talented into Pyromaniac Icon Pyromaniac, players will have to space out casts of Basic Abilities in order to maintain the bonus Ability Power. The 15% Ability Power increase also will not come into effect until after Kael'thas has been able to cast 5 abilities, making Arcane Dynamo a rather weak option for generating reliable immediate burst damage.

9. Level 20 Talents

Kael'thas Rebirth
Rebirth (Level 20) World of Warcraft Kael'thas

Increases Phoenix duration by 100%. While alive, the Phoenix may be ordered to move to a different location.

Kael'thas Presence Of Mind
Presence Of Mind (Level 20) World of Warcraft Kael'thas

Increases Pyroblast's explosion radius by 50% and reduces its cooldown by 25 seconds per enemy Hero hit.

Kael'thas Master of Flames
Master of Flames (Level 20) World of Warcraft Kael'thas

Living Bomb's spread from explosions can now also spread Living Bomb.

Kael'thas Flamethrower
Flamethrower (Level 20) World of Warcraft Kael'thas

Increases the cast range of Flamestrike by 40%. If Flamestrike hits 2 or more Heroes, its cooldown is reduced by 4 seconds.

9.1. Discussion

Rebirth Icon Rebirth allows Kael'thas to reposition his Phoenix once, providing him with additional zoning potential. This repositioning occurs from the location of the Phoenix, not Kael'thas, and can be repositioned globally. The repositioning of the Phoenix can also be used to target enemies who may have exhausted their gap-closers to escape its reach, or followup against enemies who attempt to engage or disengage out of the area of the Phoenix. The 100% increase in duration is further magnifies its strength, particularly when being used to zone away enemies from an objective.

Master of Flames Icon Master of Flames vastly increases the impact of Living Bomb Icon Living Bomb in teamfights. The beauty of Master of Flames is that the additional applications of Living Bomb will also benefit from talents that effect it, such as Sun King's Fury Icon Sun King's Fury, Pyromaniac Icon Pyromaniac, and Backdraft Icon Backdraft. Talenting into Master of Flames will force enemy teams to split up from those struck by Living Bomb in order to prevent its spread. This splitting can be capitalize on by Kael'thas and his allies, allowing isolated target to be quickly focused down.

Flamethrower Icon Flamethrower is a great option for the Flamestrike Icon Flamestrike build as it allows Kael'thas to cast his strongest Basic Ability from a much safer distance. This allows him to safely zone away enemies and more easily interrupt Heroes attempting to capture an objective such as an Altar on Towers of Doom or a Tribute on Cursed Hollow. The decrease in cooldown from striking multiple enemies with Flamestrike will allow it to be readily cast, vastly increasing Kael'thas damage output. Combined with the effect of Fury of the Sunwell Icon Fury of the Sunwell, Kael'thas will be able to trigger a volley of Flamestrike explosions that will chunk large amounts of Health from the entire enemy team.

Presence Of Mind Icon Presence Of Mind is a very weak talent that does not increase the explosion radius of Pyroblast Icon Pyroblast hardly enough to justify its selection. Even if Pyroblast manages to strike and enemy, they will most likely have split off from their team enough to negate the AoE aspect. Because of this the cooldown reduction of Presence of Mind will pretty much always only end up being a disappointing 25 seconds.
