The Idoneth Deepkin
Descending like a storm, these seaborne
raiders reave the Mortal Realms in search
of souls, using mysterious magics and
fierce seabeasts to crush their foes before
disappearing into the mists.
Child of the Sea. You have a
swimming speed of 30 feet, and you can
breathe air and water.
Soul drain. When you reduce a foe to 0
hit points, you can use a bonus action
to regain hit points equal to half your
character level plus your Charisma
modifier. Once you use this trait, you can't
do so again until you finish a long rest.
