This Comic's Cast:

As with many things in classic RPGs, once you get an item, it's never explain how you're supposed to power it. You just get to use it for as long as you like.

And then, of course, the item you used to get that item is rendered useless. Sure, maybe it'll still sit in your inventory, but good like finding any other use for it.
 
    

When evil spreads across the land, and darkness rises and the monsters roam. When the creatures of the night make beautiful music, and the things that go bump in the night go bump with greater enthusiasm. When the world is in peril and is in need of a hero...

These guys are, sadly, the best the world can hope for. These are the adventures of the heroes of CVRPG. They mean well, they try hard, and occasionally they do the impossible...

They actually do something heroic.
