Drowning Touch. As an action choose a creature you can see within 60 feet of you; the target must make a DC 20 Constitution saving throw.
On a failure, seawater begins to fill the target's lungs. The creature is restrained, cannot speak, cannot provide verbal components, and begins suffocating. It can repeat the saving throw at the end of each of its turns, ending the effect on a success.
A creature that succeeds is immune to Drowning Touch for 24 hours.
Once a creature fails a saving throw against Drowning Touch this feature cannot be used until you finish a short or long rest.
Using Drowning Touch increases Drowning Level by 1.
