The music of a deep singer whale is of such beauty that it can entrance all who hear it. After one full round of singing, all those within 1,000 feet who can hear the song must succeed on a DC 27 Will save or stop what they are doing and simply listen. Entranced creatures that suffer damage get a new save, with a bonus equal to the damage inflicted. The entrancing effect lasts for as long as the whale sings, and a deep singer whale can maintain an entrancing harmony for as long as it has air. The save DC is Charisma-based.
A deep singer whale is immune to pressure damage at any depth.
Only in the deepest oceans can one find the deep singers, a race of intelligent whales that sing with an entrancing harmony, and that are said to be the repositories of all the sea’s wisdom. Deep singers can travel to any depth in the ocean without harm, but are air breathers nonetheless and can be found on the surface replenishing its air supply. Its haunting songs can be heard sometimes echoing among the waves, rising from the deeps, and are of such melancholy beauty that even the most hardened sailors find tears in their eyes.
Deep singer whales are often accompanied by a retinue of dolphins and intelligent, non-evil sea humanoids such as merfolk or tritons, who come to learn from the whales’ song, and bring them information of the world beyond.
Some believe that deep singer whales are the first stage in the evolution of the celestial whales that swim in the oceans of the outer planes. Others believe that they are avatars of those beings, come to the world to increase their knowledge and experience before returning.
