How are you supposed to handle identifying magic items in Dungeon World? And how much of the rules knowledge do you expose the player to?
Suppose there’s an item that does something special when you tap it against a rock. Should the player be given this rule right away, or only when he actually identifies it? Suppose he taps it against the rock when he doesn’t know what it does, and triggers the effect through trial and error. Do you give them the rules then, or just describe the fictional effect and leave it at that?
For most games like D&D I would leave all of the metagame knowledge behind the DM screen, but DW is big on just revealing all of that to the players, so I’m not sure what to expect here. But it doesn’t make sense for the player to just know these things.
