Frenzied Rage

If a deep one archimandrite takes 15 or more damage from a single attack, it has advantage on all attack rolls and gains a +4 bonus to all damage rolls until the end of its next turn. For the duration, it can make one Unholy Trident attack as a bonus action on its turn.

Actions

Call of the Archimandrite

1/day

With a ringing shout, the archimandrite magically calls 1d4 reef sharks or 1 swarm of quippers, provided the archimandrite is at least partially submerged in a body of water that can contain the creatures. The called creatures arrive in 1d4 rounds, acting as allies of the archimandrite and obeying its spoken commands. The creatures remain for 1 hour, until the archimandrite dies, or until the archimandrite dismisses them as a bonus action. Each deep one within 1 mile of the archimandrite can hear this call, though these deep ones are under no magical compulsion to make their way toward the archimandrite.
