Any Creature who can breathe underwater or hold their breath (Air Genasi, Lizardfolk, Sea Elf, Tortle, Triton, Water Genasi, and Warforged), is not affected by this. You can make a STR save to return to the surface. However, by failing three times in a row you are dragged too close to Apati and take 3d8 bludgeoning damage and are flung out of the whirlpool. This ends when the DM chooses or when someone is flung. (1 Charge per Long rest.)

Deceitful Appearance: Apati turns into the Color of their surroundings rendering them Practically Invisible. This continues until Apati attacks or uses an action to reveal himself. Using detection spells can reveal Apati. 

Brand Of Apati: This is the form of a tentacle attack and when grappled Ink spills from a suction cup and forms the symbol of an octopus on any open skin (metal if a warforged). This brand gives Apati advantage when making any CHA based checks against the branded. It gives the branded Creature/Creatures disadvantage on ANY Insight checks. The last effect it has is any Creature branded cannot see Apati. (He can still be revealed by magic). The brand can only be dispelled by spells that neutralize curses.

Apati, God of Deception: Apati can change the Terrain and use many other illusory effects to gain the advantage against his enemies. During this Mythic action you can chose to cast 3 of these spells.
