Ok, I've never played this before and am giving it a go. I cannot figure out how to use an item in combat. For example, I have a vase that I can hurl at an enemy to do 20 points of fire damage. I cannot equip/use it on the main map because it says it is for combat only...but in combat, I don't see anything that I can click to use an item. Couldn't find it in the manual and I am sure it's in plain sight.
