Ring of the Ocean's Choke (5e Equipment)
From D&D Wiki
Ring, rare (requires attunement)
This ring looks like waves endlessly going across your finger. The ring feels wet when touched and tastes of salt water if licked.
When attuned to this ring, you have the ability to speak its command word to force an endless stream of water from your fist when clenched to smother a creature's head with water, causing it to drown. The creature must succeed a DC 15 Constitution saving throw or it begins to drown. A creature can hold its breath for a number of minutes equal to 1 + its Constitution modifier (minimum of 30 seconds). When a creature runs out of breath, it can survive for a number of rounds equal to its Constitution modifier (minimum of 1 round). At the start of its next turn, it drops to 0 hit points and is dying, and it can't regain hit points or be stabilized until it can breathe again. If a creature succeeds this saving throw they are unaffected by the ring and have advantage on saving throws involving withstanding drowning and suffocating.
When a creature is drowning, it's speed is reduced to 10 and takes attack actions and saving throws with disadvantage. The affected creature can continue making CON saving throws to get out of the stream at the start of its turn (DC stays the same). The creature drops to 0 hit points after a number of rounds equal to twice its CON score.
A creature can instantly get out of drowning if another creature succeeds a DC 16 strength saving throw to get it out of the stream of water. Each failed attempt at getting a creature out of the stream with a strength saving throw causes the number of rounds before it drops to 0 hit points to decrease by 1.
A creature that can breath underwater or a creature that is larger than the user is unaffected by the effects of this ring.
