When a wall of fire appears, all creatures within its area must make a single immunity to Agility. A person who fails immunity suffers 5d8 points of flame damage. A successful immunity halves the damage.
When casting this spell, you must choose which side of the wall of fire will deal damage. A creature ends its turn within 10 feet of the damage side of a wall of fire or within the area of the wall of fire takes 5d8 points of flame damage. A creature also takes the same damage the first time it enters a wall of fire in a turn or ends its turn inside a wall of fire. The other side of the wall of fire deals no damage.
When casting this spell with 5 rings or higher, the spell’s damage increases by 1d8 for each ring you use that is higher than 4 rings.
