Cold Fury

You focus on all of your anger, and clench a fist. As you do this, you recite a curse and the intense anger spreads to your body and mind. 

Casting this spell on yourself gives you several abilities. You, for the duration of the spell, gain advantage on your Strength and Intelligence checks. Your Exhaustion level also turns to level Zero for the spell's duration. (It goes back to whatever level it was after the spell ends)

For the duration of this spell, and for 5 rounds after, you gain a disadvantage on all of your Wisdom checks, as the spell fades. 

This spell can only be used once every short or long rest. After a short or long rest you can use the spell again.
