Drowning Rat Charm

Wondrous item, rare (requires attunement)

This drowning rat charm is a choker made from a mummified rat biting its own tail. You gain the ability to steal the breath of others by hitting them. You can make an attack, and if it deals damage, the target must make a DC 14 Constitution saving throw. If the target fails, it can hold its breath for 1 minute less until it benefits from a long rest. You then gain the ability to hold your breath for an additional minute.

If the affected creature was already holding its breath and runs out of time, they begin suffocating. Creatures that are already suffocating cannot be affected by this ability. An affected creature that can breathe water gains a level of exhaustion instead of losing a minute’s worth of holding their breath. You can use this ability three times, and regain all uses of this item after a long rest. You lose any benefits of this item if it is removed by you or anyone else.
