Tidal Tendrils of Duunu Mambash

Serpentine streams of pressurised water erupt from the ground surrounding the Bearer. For the duration of the spell the Bearer can perform attacks of opportunity without expending their reaction

Whenever a hostile creature comes within range of the tendrils, the creature must succeed on a Dexterity saving throw or be restrained by the tendrils until the spell ends as well as take an opportunity attack from the Bearer. A creature that starts its turn in the area and is already restrained by the tentacles must make another Dexterity saving throw after taking the Bearers attack of opportunity, on a successful save they break free of the tendrils hold, if they fail they take an additional attack of opportunity and are then thrown 10 feet away from the Bearer.

The Bearer can use a bonus action on allies that end their turns within range of the tendrils to move the ally up to half their movement speed in any direction. Creatures moved in this way are immune to attacks of opportunity during this movement
