Elemental Transformation Field
Level 18 Lurker
XP 2000

A hazelike heat rising from a desert fills the area with an oddly hued distortion. Suddenly, a companion is horribly transformed.

Hazard: The air shimmers over a wide area, concealing 10 random squares of this hazard.Perception     No check is required to see the air shimmering.     DC 25: The character can discern if any adjacent squares contain an elemental transformation field.Arcana     DC 25: The character recognizes the hazard’s nature.TriggerWhen a creature enters one of the field’s squares, the hazard attacks.AttackOpportunity Action      Melee
Target: The triggering creatureAttack: +21 vs. WillHit: The target becomes a creature of flame, taking ongoing 15 fire damage (save ends). Until it saves against the ongoing fire damage, the following effects also apply.     The target is immune to fire damage from any source other than this hazard.     All the target’s attacks deal fire damage rather than their normal type.     Any creature that starts its turn adjacent to the target takes 10 fire damage.
First Failed Saving Throw: The target is also slowed (save ends both), as more of its substance is transformed into fire.
Second Failed Saving Throw: The target is also immobilized (save ends all).
Third Failed Saving Throw: The target is permanently transformed into a nonliving column of semisolid fire and stops taking the ongoing fire damage from this hazard. Each creature that begins its turn adjacent to the column of fire takes 10 fire damage. The Remove Affliction ritual can restore the target to normal.
Special: The elemental transformation field does not attack creatures that are already under the effect of a previous successful attack by this hazard. Creatures already immune to fire are unaffected by this hazard.
