You flourish the weapon used in casting the spell, then make a melee attack with it. On a hit the target suffers 1d10 force damage in addition to the normal effects of the weapon.
While you are concentrating on this spell rainbow wisps of llight gather at the tip of your weapon. You have a pool of dice starting with 1d10. Add 1d10 to the pool every time you hit a creature with the weapon used to cast this spell. You may also use a bonus action to add 1d10 to your pool. Then at the end of your turn, you may use your reaction to release your charged up energy and fire a ring of spiraling rainbow beams. Roll all the dice in your pool, and a creature within 30ft takes force damage equal to the result. Then the spell ends.
When you lose concentration on this spell you may use your reaction to unleash some of the charged up energy. A creature within 30ft takes 1d10 force damage and the spell ends.
At Higher Levels. If you cast this spell with a spell slot of 4th level or higher, your pool starts with an additional d10 foreach slot level above 3rd.
