Antonidas by Ravoid

Level 1

Enhanced Pyrotechnics: Every 3rd Fireball hit against heroes in a row is always a critical hit and deals 50% more Ignite damage.

Firestarter: Fireball and Fire Blast always deals critical damage to targets above 90% health.

Critical Mass: Fireball now also deals critical damage at 25%, 50% and 75% of its maximum range.

Feeding the Flame: Quest: Critical hits with Fireball increase the Ignite damage of your spells by 1 %.

Level 4

Rush: Critical hits with Blast Wave increase basic abilities recharge rate by 50% for 5 seconds.

Fiery Soul: Each time Ignite deals damage increase your health and mana regeneration rates by 20% for 2 seconds.

World in Flames: All your area of effect abilities leaves behind a patch of flames that deal 55 damage per seconds for 4 seconds.
(This works with Pyroblast, Blast Wave, Meteor, Fireball with the Soul Burn talent @13 and Fire Blast with the Inferno Blast talent @16.)

Level 7

Frostfire Bolt: Replaces Fireball, deals 25% less damage but has 25% reduced cooldown and also slows enemies hit by 25% for 4 seconds.
(Critical hit condition is the same and all Fireball related talents apply)

Flame On: Fire Blast stores 2 charges.

Impact: Critical hits with Fire Blast stun the target for 1 second.
(Has great synergy with the talent Firestarter @1, reverses Fire blast's role from confirming Hot Streak to initiating it on full health targets, and with a stun to help land your other spells.)

Level 10

Combustion: Engulfs you in flames for 5 seconds, during which all spells always do critical damage.

Meteor: Call down a meteor which lands after 2 seconds dealing 900 damage split evenly between all enemies hit, always deals critical damage. Cooldown is reduced by 1 second each time Ignite deals damage, tripled if Ignite lasts more than 4 seconds.

Level 13

Soul Burn: Fireball pierces through all enemies.
(This coupled with the talent Critical Mass @1 can score multiple critical strikes with 1 Fireball cast getting more value for great aim.)

Pyromaniac: Each enemy hero affected by Ignite, increases your spell power by 10%.

Flame Throwing: Increase the range of your abilities by 20%.

Level 16

Controlled Burn: Critical hits with Pyroblast reduces enemy heroes maximum health by the amount of Ignite damage on them, effect fades after they don't take damage from Ignite for 4 seconds.

Inferno Blast: Fire Blast spreads all Ignite damage on its target to nearby enemies.

Melting Point: The last tick of Ignite deals 10% bonus damage for every second Ignite was active.

Level 20

On Fire: Takedowns activate a free Combustion for 2.5 seconds, if already using Combustion, extend the duration by 2.5 seconds.

Meteor Shower: If Meteor hits an enemy hero, another Meteor will target their location after 2 seconds. Can chain off of itself.

Pyroclasm: Pyroblast channel time is reduced to 2.5 seconds, non instant cast Pyroblasts have global range.
(This talent makes Pyroblast uncastable while a Pyroblast is already flying, to avoid sniping buildings from across the map.)

Cauterize: Fatal damage instead brings you to 35% health and then burns you for 28% of your maximum health over 6 sec. While burning, movement slowing effects are suppressed and your movement speed is increased by 50%.
