Tsamra's Spiritual Staff

You feel your daughter's spirit take hold of her staff for the duration of the spell, causing it to float in an unoccupied square adjacent to you. When you cast the spell, you can make a melee spell attack against a creature within 5 feet of the weapon. On a hit, the target takes force damage equal to 1d8 + your spellcasting ability modifier.

For the duration of the spell, as a bonus action on your turn, you can move the weapon up to 20 feet and repeat the attack against a creature within 5 feet of it.

Your spellcasting ability for this spell is Constitution.
