Ataxia

You submit control of your body to the weave, and let magic itself decide what you will cast. A random spell effect will occur, based on what level you cast Ataxia at.

Use a random number generator.

 At Higher Levels: When you cast this spell at 2nd level or higher, you may cast a spell of that level OR a series of random spells equal to the slot level.
