Raven Queen's Blessing: With each strike of this blade, undead enemies become increasingly vulnerable to cold damage. Each time you strike an undead enemy with this weapon, the enemy gradually becomes more vulnerable to cold damage. Immunity becomes resistance, resistant becomes unresistant, unresistant becomes vulnerable, and vulnerability can stack up to 25 times for a total of 25% vulnerability to cold damage. This effect is applied on every hit and each stack lasts 15 seconds.
