My RES tank Lich just took 43 damage from a Ryemei, and then 358 damage from the next one.

Ryemei ignores Arcane Order (both ways), and its critical damage is multiplied before RES.
I imagine Redgull impacts ignore Arcane Order too.

I'm not sure if Redgull crits are before DEF/RES, but given how much damage I was doing against tanks, they probably are.

All lightning criticals apply before defense and resistance. Due to the way they work, this probably won't change.
