I have thousands of them like snacks antidotes. What am I supposed to do with them? Please let me exchange them for something a little more useful.

Yes how many do you need ,I can’t see giving up a turn to use one. Uselessly and since you have downgraded the reward there a slap in the face.

There was a time when battle items were useful, but I agree they're mostly obsolete at this point. I think SP should just phase them out entirely.
