A mythic water elemental can expend one use of mythic power to create a 60-foot-radius bust of pressurized water. Creatures in the area must attempt a DC 22 Fort save. Success means the creature is sickened for 1d4 rounds; failure means the creature is nauseated for 1d4 rounds and sickened for 1d4 rounds after that. If the elemental expends two uses of mythic power, creatures nauseated by this ability also take slam damage. Creatures with the aquatic or water subtypes are immune to this ability.
The save DC is Constitution-based.
The elemental can use this ability on a creature it has grabbed. If a trapped creature cuts itself free, the hole heals itself closed at the start of the elemental’s next turn, allowing it to use swallow whole again.
If a water elemental and its opponent are touching water, the elemental gains a +1 bonus on attack rolls, damage rolls, and bull rush and overrun combat maneuver checks. If it or the opponent are touching the ground, the elemental takes a –4 penalty on attack rolls, on damage rolls, and to its CMD to resist bull rush and overrun attempts.
Environment any (Plane of Water)
Organization solitary, pair, or gang (3–8)
A mythic water elemental comes from the unknowable depths of its home plane, predating the current civilizations and gods. A witness to ancient and bizarre acts of life-creation, it is unconcerned about the interests of mortal creatures.
