Bash

Bash is a passive ability that gives a unit chance to deal bonus damage and stun its target on attack. The bash ability can be gained by skills or the items Skull Basher and Monkey King Bar.

Stacking
The stacking rules for the bash ability is different for melee and ranged units.

Melee
Bash cannot stack in any way on melee units. If a unit has a skill that grants bash, he will not benefit from any item that also gives the ability.

Ranged
Ranged bashes stack, but in diminishing returns. See: Chance Stacking
