As two actions, you create two 2-meter radius pools of acid on the ground within 20 meters that last for the duration. The pools can’t occupy the same space as a creature or object and their area is difficult terrain. A creature that enters the spell’s area for the first time on a turn or starts its turn there must make a Fortitude saving throw.
On a failure, it takes 2d8 acid damage immediately and additional acid damage equal to half the amount of acid damage dealt at the end of its next turn and its armor or natural armoris corroded 1 until the end of your next turn.
On a critical failure, it takes twice as much damage and its armor or natural armoris corroded 2 until the end of your next turn.
On a success, it takes half as much damage.
On a critical success, it takes no damage.
You can create one additional pool and increase the damage by 1d8 for each additional mana expended.
