I'm disappointed with Alchemy

[peaches]

Maybe wicked wheel is physical damage and not magical?

I suppose it could be. But that would mean Slipstream is physical too. Which brings another annoying point to light - too many attacks aren't clear on their damage type. So many look magical but are physical, and the reverse.

Regardless, I don't think the amount of resistance we've been given access to is adequate enough to do anything. You'd be better off saving your potion CD to use a health potion.
