Elemental Barrier

When the spell is cast, choose Fire, Cold or Lightning as the element and a small barrier pops up out of the ground around you.

The barrier is 10ft x 5ft x half your height. Any elemental attack that you do that is the same as the barrier's increases that damage by 3d6.

The barrier counts as Half Cover.

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