I used to play a LAN game. Run around exploring a dungeon, find treasures, weapons, etc. and use them to whack on other players. One of the things you could find was a magic feather that let you walk through walls when wielded. Useful but not too powerful since it was expended with use. After about 15 minutes, if nobody had won, the game went into Armageddon mode by teleporting everyone to a small hostile room to cage match until only one survived. So I used the feather then and hopped into the wall. I could still hit and be hit by adjacent players, but was immune from all the environmental hazards that only existed inside the room.
Next game we played had a house rule to not do that anymore.
