Chaotic Burst

Universal chaos calls to you. Until the spell is triggered, your weapon is empowered with chaotic energy which upon a successful strike, explodes forth with a random element. Roll 1d6 and 1d8, with the first roll determining the amount of damage and the second determining the element.
[1 - Acid; 2 - Cold; 3 - Fire; 4 - Force; 5 - Lightning; 6 - Poison; 7 - Psychic; 8 - Thunder]

At Higher Levels. When you cast this spell at a spell slot of 2nd level or higher, the extra damage increases by 1d6 for each slot level above 1st.
