CX-2 Second Unique Focused and Determined states :
"
At the start of battle, CX-2 gains 10% Max Health and Offense for each other Empire ally. At the start of each encounter, CX-2 Stealths for 2 turns.
While another Empire ally is active, CX-2 ignores taunt effects on his turn.
Whenever CX-2 uses an ability against the same targeted enemy that he did in the previous turn, he gains 50% Critical Chance and Potency (stacking, max 100%) and all Empire allies recover 15% Health and Protection until he uses an ability on his turn against a different target.
Whenever CX-2 uses an ability against the same targeted enemy 3 times in a row, inflict Order 66 on that enemy for 2 turns, which can't be copied, dispelled, evaded or resisted.
"
But if you go ahead and check how its coded and works you will see at the end CX-2 gives Lord Vader 25% Ultimate charge upon inflicting Order 66 on enemies.
Attached a picture showing the relevant part of the code.
