For a healer does crit or heavy atk affect to healing?

[I'm looking for a girl]

I mean if the healer has more crit or heavy attack, the heal will be more?
Or... to increase healing the only affected thing is base dmg which is dmg?

crit I am not sure about, it probably can, but yes a heal can "heavy attack" which makes you heal double the amount

Both applies.

You can get min and max heals base on your CRIT. You can get X2 values off your heals base with your heavy attack.
