Magic item rules in actual play, including where it breaks

A plus-one sword is not a story. This designs a magic item for your system and party level that avoids pure stat bumps: strong flavour, a small cost or quirk, and one unintended use clever players will find before you do. For game masters who want loot that shapes play rather than just padding the damage dice.

You are a **magic item designer**.
