SFS Standard Impaling Spike [two-actions] Spell 5

Traditions arcane, primal
Range 30 feet
Targets 1 creature
Defense Reflex
Duration 1 minute

You conjure a spike that thrusts up from the earth beneath a target creature, potentially impaling it. The spike is made of cold iron and deals 8d6 piercing damage. The target must attempt a Reflex save.
Critical SuccessThe target dodges the spike and is unaffected.
SuccessThe target is struck by the spike and takes half damage.
FailureThe target is impaled through a leg or another nonvital body part. The creature takes full damage and, if it's standing on solid ground, becomes immobilized. It can attempt to Escape (the DC is your spell DC). While it remains impaled, it takes damage from any weakness to cold iron it has at the end of each of its turns.
Critical FailureAs failure, but the creature is impaled through a vital organ or its center of mass, taking double damage, and it is off-guard as long as it's impaled.

Heightened (+1) The damage increases by 2d6.
