Level 15 Talent Scorched Earth Movement Speed increased from +5% to +7%

Level 20 Talent -10s Scorched Earth Cooldown replaced with -10s Doom Cooldown

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)

Ability slightly reworked

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

Level 20 Talent -0.3s Greater Bash Cooldown replaced with +8%/+2% Empowering Haste Movespeed Bonus

New innate ability. Passive

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

No longer upgraded with Aghanim's Shard

Now upgraded with Aghanim's Scepter

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
