Any Hit has a chance to Light Stun the target, interrupting their current action and preventing them from taking actions for a fraction of a second. The chance is based on the damage dealt, up to 100% base chance for Hits that deal 100% of the target's maximum Life. Chances lower than 15% are treated as 0%.

Physical damage, and player (but not monster) Melee Damage, each have 50% more Light Stun chance. For players, these bonuses are multiplicative with each other.
