Ocean Domain

Clerics of the Ocean domain sway and pitch with the force and power of the tides themselves. They embody the rough, roiling temperament of the sea itself: striking with all the ferocity of a whirlpool, and healing all the tenderness of a gentle reef. Clerics of this domain are as slippery as a moray, and equally deadly.

Deities who grant this domain include Istishia, Lir, Neptune, Oceanus, Poseidon, Sekolah, Sobek, Tethys, Ulutiu, Umberlee, and Valkur.
