Sword of Truth
From DivNull RPG
Created long ago to destroy arcane magic users, this intelligent longsword became cursed, turning into the Sword of Lies, and was incarcerated in the Banewarrens. It remains dedicated to destroying arcane spellcasters, however. Should the evil curse on this blade can be removed by powerful caster, it will return to its original alignment and abilities, listed here.
Whoever bonds themselves to this sword gains the following abilities:
When you hack and slash a monster with the magical and intelligent tags, take +2 and your damage dice becomes a d12.
When you are targeted by an unwanted spell, roll+bond. On a 10+, the spell is prevented entirely. On a 7-9, the spell is cast but does not effect you.
You see all things as they truly are. If you tell a lie, this power stops working until you next make camp.
