Bracer of Liberty
Links that formerly chained enslaved people, and blood of their enslaver.
Dozens of links from the chains of slaves were shattered apart and half-melted into this bracelet, which pulses with potent psychic energies. If the wearer loses control of their will, the links sear with retaliatory heat and bring the wearer to their senses, as designed by the original creator, the late gnoll executore Glaucia Evora. Executore heralds prefer to lend these items to their comrades, as such heralds prefer to confront challenges of willpower on their own merits.
While you are wearing the bracer, whenever you start your turn charmed you may choose to take 1d6 fire damage. If you do, you can act until the start of your next turn as if you are not charmed. If you have immunity to fire damage, the bracer provides no protection.
