I was working on a magic item belt in Pathfinder. The belt is going to provide the standard boosts to Str/Dex/Con.
However, I also want it to have a split property, and I'm struggling with how to pull it off: I want it to give me a continuous activation of reduce person or enlarge person or for neither one to be active.
It's simple to just add both enlarge and reduce to the belt as continuous costs, but that doesn't give me the effect I want. At the same point in time I can't just say that one effect is happening but not the other one. I don't want to go the route of x-activations.
Is there some way to work an activation and deactivation into the continuous item?
