concentration, 1 minute/mana

As two actions, small fissures continuously open and close on the ground in a sphere centered on a point within 20 meters for the duration. The fissures turn the ground into difficult terrain for the duration.

A creature that enters the spell’s area for the first time on a turn or starts its turn there must make a Reflex saving throw.

On a failure, it takes 3d8 bludgeoning damage and is knocked prone.

On a critical failure, it takes twice as much damage.

On a success, it takes half as much damage.

On a critical success, it takes no damage.

As an action, you can cause the fissures to move 2 meters in a direction that you choose at the start of each of your turns. As an action, you can stop the fissures from moving if it is within 20 meters of you. Any difficult terrain that is no longer in the fissures returns to normal.

Augment
You can augment this spell with the following options, expending mana for each option.
  • You can increase the damage by 1d8 for every two additional mana expended.

  • You can expend 1 additional mana so the duration changes to 1 hour/mana.
