Spirit Breaker build & guide (7.41)

Charge of Darkness

Spirit Breaker fixes his sight on an enemy unit and starts charging through all objects, starting at 25% of the bonus speed and reaching his max speed after 1.5s. All enemy units passed through and the targeted unit will be hit by a Greater Bash. If the targeted unit dies, Spirit Breaker will change his target to the nearest enemy unit to that location.

Aghanim's Shard: Increases Charge of Darkness Bonus Speed by %bonus_movement_speed%.

Bulldoze

Spirit Breaker gains movement speed and status resistance to ram through enemies. Can be used while charging.

Greater Bash

Gives a chance to stun and knockback an enemy unit on an attack. Deals a percentage of movement speed as damage.

Aghanim's Scepter: Increases knockback. If a knocked-back enemy collides with another enemy, the second enemy is bashed (creeps only receive 20% damage), and the original target takes 25% of Greater Bash's damage again.

Planar Pocket

Barathrum gains magic resistance and distorts reality around the selected hero, making any unit-targeted spells cast by enemy heroes get redirected towards Spirit Breaker. Can be cast on both allied and enemy heroes, but only spells cast by enemies of Spirit Breaker will be redirected.

Empowering Haste

Spirit Breaker gains bonus Movement Speed for a duration whenever he stuns an enemy. Effects from multiple stuns stack and have independent durations. Duration pauses during Charge of Darkness.

Nether Strike

Spirit Breaker slips into the nether realm, reappearing next to his hapless victim. Upon reappearing, a Greater Bash of the current level occurs and deals bonus damage. Knocks back for double the normal distance.

Aghanim's Scepter: Greatly increases knockback.
