Anyone can explain the exact behavior of Knockback?
As soon as you have Knockback, you push the enemy one square away. If you push it into a wall, it destroys the wall and does some more damage. Into another mob, same amount of damage.
The damage is equal to %knockback of what? Enemy attack? your attack?
Does the extra damage counts as an additional hit?
Also, if you push the enemy into another one, the other one also takes damage. Is it equal to the knockback damage?
