Activation bits for menu skills?

JesterEmblem_EX · March 2, 2026, 5:57pm

This basically. Certain menu skills have a bit set in u3A/u3B to prevent them being activated more than once a turn. By default I suppose you could use u3B since there’s not even 8 skills using bits, but I managed to use all of them
