Enchanted emerald bolts have a 55% chance to activate the Magical Poison enchantment. Upon activation the target is poisoned for 4% weapon damage. This effect does not stack with weapon poison but it does stack with Cinderbane gloves.
This effect can be triggered with auto attacks and abilities. Abilities will only consume bolts in PvP. Multi-target abilities such as ricochet can trigger the effect separately on secondary targets.
Abilities that hit multiple times such as rapid fire have a chance to trigger it on each hit separately.
