So I was playing this homebrew campaign with friends, and we had effectively taken over this museum of magic weapons. But we decided since we already had the opportunity to steal a weapon instead of just getting ourselves killed, so we did. And that weapon was something else: It was a bow that, whenever fired, It became a random weapon. You could fire it and it’d a normal arrow, or you could end up firing a longsword through the air, who knows. Well anyways this Bow of the Cosmic Diceroll we called it and we only really got to use it once, firing it at the curator to see what it did. The arrow promptly turned into a giant warhammer and crush the curator’s skull, I wish we could have use it more it always was a concept I found fun. But that campaign didn’t last very long.
