Blight of the Kraken

Positives:

+15ft tremor sense

Special grapple attacks through tentacles. They act as improvised weapons and you can grapple creatures. Using a tentacle locks that respective arm/leg out of action. (Half move speed or one hand free)

Tentacles: (add this as a weapon, you have 2, one on your leg and one on your arm) melee weapon, martial, damage 1d8 slashing, 15ft reach, grapple enemies with a strength DC (10+str mod) check. Works on enemies up to one size larger than you. Whilst grappled you can use an action to,

Sweep the legs: target performs another DC (10+str mod) strength check, if they fail they become proned.

Attack: use your other hand to strike with a weapon.

Grappled creatures will attempt to break free every turn.

Negatives:

You permanently have the blinded condition Unless a creature is grappled.

Your natural sight is replaced with short-range tremor sense.

You require moisture. If you don't make contact with a body of water once every 4 hours, you take a level of exhaustion per hour afterwards and you cannot use your tentacles. Rain takes an hour to "moisten" you.

You require help to move naturally since you're missing a leg. otherwise your move speed is set to 10ft. Use walking sticks or mounts to help you. (when tentacles aren't active)
