I'll preface this by apologizing in advance if this has been asked and answered already, but didn't see any posts talking about it.
I was reading Wind Homies skill descriptions and I noticed that all of his skills (Once fully upgraded, top half of bottom path) say they deal damage proportionate to targets Max HP.
I was under the impression that, that meant all damage was purely calculated off enemy HP and didn't take the monster using the skill ATK into account. Is that dated/false information or is Wind Homie just an exception to that? I was curious because it seems everywhere recommends to build him on Atk/Crit Dmg/Atk even though it has the 'proportionate to' scaling rather than the 'according to' alternate that I was under the impression used both scalings.
