I did not realize that the Heal ability that Soapwort has is similar to the absorbs HP ability. (like Alpinia and Kerria).

I just tried her out on a 70% debuff team (Alpinia team) and she was remarkable.
I just got her last week in gacha so she has no slots or ampy and already outperforms a fully slotted and max ampy Alpinia!

Its that 3.75x counter attack vs only 2.2 for Alpinia that is responsible

Ill get her to full power next, but takes time. It will be the next event before I see what she really is capable of.
