Restraining Tentacles

Your tentacles are a natural weapon, which counts as a simple ranged weapon with which you are proficient. It has a normal range of 5 feet and a long range of 15 feet, and it has the special property. You can only attack with your tentacles if there's nothing currently held in them.

On a hit it deals 0 bludgeoning damage. A Large or smaller creature hit by a tentacles is restrained until it is freed. The tentacles have no effect on creatures that are formless, or creatures that are Huge or larger. A creature can use its action to make a Strength check, freeing itself or another creature within its reach on a success. The DC for this check is equal to 8 + your Strength modifier + your Proficiency bonus.

While you have a target restrained by your tentacles, you cannot attack another target with them.

When you use an action, bonus action, or reaction to attack with the tentacles, you can make only one attack regardless of the number of attacks you can normally make.

This Feat also grants a +1 bonus to strength
