Céll's Frozen Guard

Three frozen blades appear. Until the spell ends, from use or being dispelled, these blades float around you, following you around. You may dismiss the blades at will.

While conjured you may spend these blades, for the following effects, each blade can be used only once;

Whenever a creature attempts a weapon attack roll against you may use reaction in an attempt to parry the attack to lower its effectiveness, expending a blade and adding +3 to your AC for that attack alone.

You may also use a bonus action to fire a blade at a target, also expending it. Each blade does 1d8 cold damage, and has a range of 120ft.

The spell ends once all blades are expended or dismissed. Casting this spell while still in duration will dismiss any remaining blades from previous castings of the spell.

While you are incapacitated or sleeping any remaining blades will attempt to fire at the closest enemy. 

At Higher Levels: When you cast this spell using a spell slot of 3rd level or higher, the spell creates one more blade for each slot above 2nd.
