Crooked Moon Tentacles

Within the dark smile of the moon you summon four black tentacles around yourself in a 50ft radius, which you can move all four to a different place within that radius as a bonus action. Each tentacle can be controlled individually within the given range. If you attack with one of the tentacles roll to hit, if it hits it deals 2d6 force damage, and the target must make a Strength saving throw (DC + your spellcasting modifier). On a failed save, the target is restrained by the tentacles and must make another Strength saving throw to free themselves. On a successful save, the target takes half damage , is pushed 10ft and is not restrained, allowing them to take their turn as usual.
