Arcane Cloud

Create a concentrated cloud suffused with arcane energies which fills an area. Any creature which begins, ends, or spends any part of its turn within the cloud must pass a health save, or take damage at the earliest sensible point in time on their turn. On each of your turns, you may move the cloud 5 ft.

Creatures within the cloud are blinded and concealed while they remain within the cloud.
If multiple Arcane Clouds overlap the same space, only the most damaging one deals damage.

Dissipate d8:
At the start of each of your turns, roll a d8. If you roll a 1, the cloud disperses.
A strong wind can disperse the cloud sooner, or move it.

You can end this spell as a fast action.

Instead of casting this spell normally, you may create a cloud which deals no damage.

Suggested Backfire: The cloud appears centered on you.

Affinity:
When you take this class, choose which element your Arcane Clouds are.
Whenever you cast this spell, it will normally be of that element.
You can try to cast this spell using a different element, but must pass a DC 20 test of Spellcraft each time to change the element from what it normally is.
