Tentacle Whip

You make a hand motion causing a black tentacle to emerge from your hand. This tentacle extends to hit a creature within range requiring a ranged spell attack using your spell attack bonus. On a hit the target takes 1d8 bludgeoning damage and can be pulled 5ft towards you if the creatures size is large or smaller.

At higher levels you imbue the tentacle with lightning causing it to deal extra damage.

This spells damage increases at level 5 (1d10 lightning), level 11 (2d10 lightning) and level 17 (3d10 lightning)
