Kraken's Call

Frequency once per day

You call forth the sleeping krakens of the deep to crush your enemies. You open a dozen small portals to some lightless, watery abyss in a within 120 feet. The powerful tentacles of a kraken reach through to grab at each creature in the area. Each affected creature takes |options:area-damage] damage depending on its save against the higher of your class DC or spell DC. You can Sustain the call up to 1 minute. The first time you Sustain it on each subsequent turn, each creature in the area not already by the tentacles must attempt the save.

Success The creature is unaffected.

Failure The creature takes full damage and is grabbed by a tentacle. A creature that's still grabbed by a tentacle at the end of its turn takes ] damage. The tentacles' DC and AC are both equal to the higher of your class DC or spell DC. A creature can attack a tentacle to attempt to free the creature trapped by it; a tentacle is destroyed if it takes 30 or more damage in a single round.

Critical Failure As failure, but double damage.
