Requires at least 65% Ultimate Charge to activate.
Ultimate Charge: Lord Vader gains Ultimate Charge when he uses Dark Harbinger. If Lord Vader is the Leader, when debuffed Dark Side allies receive damage he gains 2% Ultimate Charge, increased to 3% if that ally was an Unaligned Force User.
Lord Vader gains 50% of other Dark Side allies' current Mastery (stacking) until the end of the encounter, then they lose that much. Empire and Dark Side Unaligned Force User allies don't lose Mastery from this ability.
If 100% Ultimate Charge was used, Lord Vader instead gains 75% Mastery from this ability, dispels all debuffs on himself, takes a bonus turn, reduces his cooldowns by 1, and gains Ashes of the Republic for 5 turns, which can't be copied, dispelled, or prevented.
These Mastery gains will only trigger if the character has more than 0 Mastery.
Ashes of the Republic: Lord Vader's abilities gain additional effects; enemies defeated while this is active can't be revived; Lord Vader is immune to Ability Block, Healing Immunity, and Shock; can't gain Ultimate Charge
