Expeditious ExcavationSpell 2
EarthTransmutation
Source Gods & Magic pg. 107
Traditions arcane, primal
Cast Two Actions somatic, verbal
Range touch; Area cube of dirt 5 feet across or smaller
You remove loose dirt, dust, gravel, sand, and the like (though not solid stone) up to the size of a 5-foot cube. Any Medium or smaller creature standing atop the earth when the spell is cast must attempt a Reflex save or Acrobatics check.
Success The creature is unaffected and can choose to either descend the pit without damage or move to the nearest available space of its choice.
Failure The creature falls prone in the nearest available space of its choice, or falls into the pit if it prefers.
Critical Failure The creature falls into the pit excavated by the spell and lands prone, taking falling damage as normal.
Heightened (+2) The spell can excavate an additional 5-foot cube of earth. If you excavate all four 5-foot cubes beneath a Large creature, it must attempt a Reflex save or Acrobatics check, as above.
My question is, if you cast Gravity Well above the area that Expeditious Excavation has been cast, would the enemy(s) fall directly into the pit in the ground or could they opt to fall on one of the adjacent squares? If all the creatures fell on top of each other in a single square in the pit, would then a flaming sphere deal damage appropriately to all enemies in that square?
