Cg officially released his kit when the clues dropped.
C3po is the first character to not use ability mats; all 5 abilities Wil be zeta only and he will not attack or buff or debuff anyone at any time. He will however annoy r2 anytime he's on the battle field and instantly defeat any han solos on the field.
Nor can c3po be geared past lvl 1. ??
