Great topic so far by the way.

I just wanted to add that Dodge is supposed to be the "resist" of physical as you all know but it's very uncommon in the game. Another thing that is important to note imo is that resist can be / go negative and actually boost elemental damage, something that doesn't exist for physical.

Flay skin is an amazing skill that encourages synergy between both type of damage and the game could use more of them, I think.
