Together, the spell creates both a focused shell of flame around whatever it’s drawn on and a gentle protective layer of air to keep the object inside cool.

Lastly are the two flame spells.

One (orange) uses dispersion to produce the flames of the outer shell, these flames gently emitting from the region.

The other (blue) uses gather and convergence signs to focus and contain the flame to the region of the shell

Next is the layer responsible for the fire shell. By adding levitation signs to @ColorOpm’s spell, we make the shell float a few inches from the object, leaving room for the air cushion below. No fire sigils are present in the shell. For that, we have the outer spells.

The central spell uses this base to, with the help of an aeriform sigil and cooling signs, produce a protective cushion of air. This continually replenishing layer of cool air helps to protect whatever the spell is drawn on from the flames

The main component of the spell is based on the water shell spell used by Coco and Agott in chapter 8. Using window signs, @ColorOpm devised a method to make the shell follow the shape of what its drawn on rather than form a sphere around it. This was the base for my design
