Ink Cloud The octopus emits a cloud of black ink in a 30-foot emanation. This cloud has no effect outside of water. Creatures inside the cloud are undetected and can't use their sense of smell. The cloud dissipates after 1 minute. The octopus can't use Ink Cloud again for 2d6 rounds.
Jet (move) The octopus moves up to 200 feet in a straight line through the water without triggering reactions.
Writhing Arms The giant octopus makes up to four Strikes with different arms, each against a different target. Each attack counts separately for the octopus's multiple attack penalty, but the penalty doesn't increase the penalty until the octopus has made all the attacks. If the octopus subsequently uses the Grab action, it can Grab any number of creatures it hit with Writhing Arms.
Giant octopuses are found in the heart of deep, dark oceans.
