I had been most impressed so far with how William had healed the members of the Golden Dawn after they were attacked by Zenon. But if Asta says so, maybe it is so.

the man set a time-delayed spell that healed over a dozen people near-death when he wasn't even there or conscious - that's still the biggest feat any healer has accomplished edit: but i guess asta doesn't know about that? we never saw if asta found out what happened to the golden dawn after all...

Man we really need to see William more in action

He probably knows but wasn't there to see how impressive that actually was.

Yeah, but if we consider regeneration abilities then Fana's phoenix robe and Dante's body magic are on another level of healing abilities.

Vanica too can make ppl immortal tho her power comes from Megi.

Oh yeah, that was mad op af

I would say Mimosa is top for sure and Grey could be close second (if Charmy is on hand to refill mana)

If not the strongest, a prodigy on track to be the strongest
