Level 25 Talent Doom applies Break replaced with Permanent Scorched Earth (ability becomes toggleable with no mana cost and a 2.5s cooldown between toggles)
When Doom attacks enemy heroes, he applies a curse upon them. After 2.5s, the cursed hero bursts with a pillar of fire, damaging itself and all enemy units in a 66 AoE for 15% of the damage taken from Doom (the hero) over this duration, including damage from the attack that applied the curse. If the cursed hero's level is a multiple of 6, the curse damage and radius will be increased by 66%
Now the default cast gained on learning Devour is the one that grants abilities of devoured creeps, and alt-cast state keeps the ones that Doom currently has
Cooldown decreased from 70s to 66s
Now upgraded with Aghanim's Shard
Replaces cooldown with 2 charges with 66s restore time. Allows to devour Ancient Neutral Creeps. Gained spells also have 20% bonus AoE and 40% Spell Amplification
Spirit Breaker gains bonus Movement Speed whenever he stuns an enemy. Effect depends on the unit type: stunning a hero will provide a 8% bonus for 2s, while other units provide 2% for 1s
Effects from multiple stuns stack and have independent durations. Bull Rush duration is paused during Charge of Darkness, but it can still gain new stacks. This effect allows Spirit Breaker to go over the max movement speed limit
Increases knockback by roughly 30%. If a knocked-back enemy collides with another enemy, the second enemy is also bashed, and the original target takes 25% of Spirit Breaker's Greater Bash damage again
This effect is applied to Charge of Darkness and Nether Strike as well, since those abilities use Greater Bash
Creeps take 25% damage of repeated damage
Bodies of killed units keep flying and pushing enemies
Whenever Gyrocopter damages an enemy with attacks or abilities, he gains + 1 movement speed per hero and + 0.5 per creep. Duration is 3.9s + 0.1s per level. Effects stack independently
