The upcoming SSR (Raphael light) seems to be really, REALLY bad according to the JP wiki.

Charm is an unreliable source of cc until it procs.
Her mode gauge reduction is situational since not every fight is a boss, let alone one with a gauge. And correct me if I'm wrong, but since her ATK debuff is A-Frame, it clashes with the debuffs or Hero Soul's right?

And I don't know what the third ability means but it sounds very situational.
Reduce light attribute damage / enemy charge turn by 1 for enemy unit

But anyway my question is for anyone who had already bought an Easter gacha, do you know if the gacha is unlimited or a limited to one purchase only thing?
And unless I missed it somewhere, how long did they say that this gacha will last? I kind of want to buy it before Raphael comes out because I don't want her at all.
