Conjure Icicle

You create 6 small icicles that float around your body. They last until they are used up or the spell ends. However, If you are attacked by an area of effect fire or thunder damage spell or effect, the icicles will be destroyed and the spell ends. Before the spell ends you can use an effect. You may use as many icicles per effect as you wish.

Icicle shot: As a bonus action, you can launch as many of them icicles at your targets as you want. For each icicle launched at your opponents, make a spell attack for each one. On a hit, the target takes 2d10 ice damage on hit. The icicle then fades.

Icicle Shield: As a reaction, when you are hit by an attack, you can use an icicle to attempt to intercept the attack. For each icicle used up, increase your AC against the triggering attack by 2. The icicle is then used up.

At higher levels: For each level above 3rd, you can create an extra icicle.
