This could possibly happen elsewhere with other potions too, I don't know, haven't had cause to test it anywhere else myself. And maybe it's not a bug, but it sure seems like it shouldn't eat dualcast to drink a potion.

this is the same as using sprint consumes dualcast. just the way the system works.
