Considering helping out on the wiki to keep it updated - in particular the changed unique items need to be updated to reflect 2.6.0 changes.

Mods and base items have been updated to 2.6 values - skill progressions on some skill gem pages may need updating or some bugs need to be fixed.

Knockback

From Path of Exile Wiki
Jump to: navigation, search

Knockback is an on-hit effect that slightly pushed targets away from the attacker. A knockback does not stun or interrupt the target's actions.[1]

Mechanics

Knockback always moves the target away from the attacker, for instance if a projectile chains from a farther-away enemy and hits a closer enemy in the back, the closer enemy will still be pushed away from the caster. Being knocked back counts as moving, and the target will suffer the increased damage over time from bleed.

The default knockback distance is 4 units.[2] Knockback speed is constant, and is 37.5 units/s.[3]
