Abyssal Gravitation

Whenever this spell is cast, all creatures within 75 feet of the caster must make a Strength saving throw. The DC for the saving throw is equivalent to the caster's spellcasting ability score. All creatures that failed are pulled up to 50 feet towards the caster. All creatures that succeeded are pulled half of the distance. All creatures pulled into the same space as the caster are rendered stunned until the start of their next turn. The caster may make a melee attack against a creature stunned in this way as a bonus action.
