Darkest Night

When you consume the final Deathstalker's Mark from a target or your target dies, gain 30 Energy and Darkest Night, causing your next Envenom cast with 5 or more combo points to critically strike, deal 35% additional damage, and apply 3 stacks of Deathstalker's Mark to the target if no other Deathstalker's Mark is active. Envenom cast with Darkest Night does not consume a stack of active Deathstalker's Marks.
