Tidecaller's Blessing

You bless somebody with the power of the ocean. you target one willing creature within range. three glowing orbs start levitating around them. whenever the target damages a creature, one of the orbs strikes with the attack, dealing 3d6 magical bludgeoning damage and the target must make a Strength saving throw or have its speed reduced to 10ft until the end of its next round.

At Higher Levels. if you cast this spell with a higher level spell slot, you grant your ally one additional orb per spell slot level above 3rd.
