concentration, 1 minute/mana

As two actions, squirming, ebony tentacles fill a sphere on the ground that you can see within 20 meters. For the duration, these tentacles turn the ground in the area into difficult terrain.

A creature that enters the spell’s area for the first time on a turn or starts its turn there must make a Reflex saving throw. A creature that starts its turn in the area and is already restrained by the tentacles takes 2d6 bludgeoning damage.

On a failure, it takes 1d6 bludgeoning damage and is restrained for the duration.

On a critical failure, it takes twice as much damage.

On a success, it takes half as much damage.

On a critical success, it takes no damage.

At the start of each of your turns if the tentacles are within 20 meters of you, you can cause them to move up to 2 meters in a direction that you choose. If you spend an action, you can move them up to 10 meters.

A creature restrained by the tentacles, or one that can touch the creature, can use an action to make a Brawn or Nimbleness check (its choice) against your spell save Difficulty.

On a success, the target is freed.

When the spell ends, the tentacles wither away.


You can increase the damage by 1d6 for each additional mana expended.
