Sypha’s Orbiting Icicles

You create six floating icicles in your space.  They float in the air and orbit you for the spell’s duration.  When you cast the spell–and as an action on each of your turns thereafter–you can expend one or two of the icicles, sending them shooting out as a ranged spell attack at a target within 60 feet, or as a melee spell attack at a target within 5 feet.  On a hit, the target takes 1d8 piercing damage and 1d8 cold damage.

While icicles are still orbiting you, you gain an AC bonus equal to the number of icicles orbiting you (maximum +3 to AC).  If you take fire damage, one icicle melts for each 10 points of fire damage taken. 

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the number of icicles created increases by two for each slot level above 3rd.
