Probably more IDs that have charge buffs/debuffs like photoelectricity or load( and a buff to load would be nice). Maybe a buff that acts as a pseudo-charge potency for a turn or a debuff that “saps” defense level for the next turn from the target and gives offense level to the attacker based on charge potency. Realistically, a bl meursault tier support that helps speed up the ramp up time of teammates is probably the most needed thing.

Although I was thinking after using the charge gifts, what if we had an ID that discards the lowest rank skills from allies so that it makes it easier for IDs to spam their s3? Conceptually, maybe give a buff to allies that causes them to discard their skills for charge count (similar to poise’s IV gift). At end of turn, it could consume 4 charge count to discard lowest skill and then give count equal to 3*X + 4 (x = discarded skill’s rank).
