Necrotic Wounds

Necrotic Wounds is an Unholy death knight PvP talent, available at level 30.

• The Necrotic Wound debuff lasts for 12 seconds from when the first wound is converted. When its duration ends, all of its stacks fall off at once.
• The Azerite essence power Conflict and Strife/Major grants this talent when used by an Unholy death knight—despite the tooltip still specifying that it grants Necrotic Strike. It actually grants both.
