Artillery Famine Acid

You unleash multiple bolts of ice arcing towards a spot in range. The ice freezes a 75-foot radius and every creature not immune to acid must make a Dexterity saving throw. A fail takes 9d8 acid damage, a success takes half damage. The creatures takes half of that damage when they start they're next turn.

Casting this spell reduces your initiative by 2 for 1 hour every other casting (This doesn't effect your initiative order if you're already in combat when this effect happens, but it takes effect immediately afterward).

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, the damage is increased by 2d8 for each slot level above 6th.
