Lets the caster walk through the air as a raging, lightning-filled tempest. The caster's melee attacks are strengthened, electrified, and strike all adjacent foes. The caster also flies, is more evasive, gains immunity to poison and miasma, and resists electricity. They can launch themselves as a lightning bolt, blasting through everything in their way. The damage and evasion granted by storm form are highly dependent on the power with which it was cast.

While transformed, any equipped weapons and armour are melded.

“Stormform is said to cause
A tempest of winds and showers,
Beware its powers, beware its powers.
Though its coming brings the gods their night,
It obliges a bloodred spren.
Beware its end, beware its end.”
-Brandon Sanderson, “Words of Radiance”. 2014.

Storm Form is a level 7 Transmutations / Air spell.


Storm Form turns you into lightning, with the following changes:



  • All equipment slots except for rings and amulets meld into the new form.
  • Unable to throw items.
  • Requires high spell power to be effective.


Storm Form is a high damage form that scales well with spell power. At low spell power, Dragon Form deals more damage to single targets.

This form is surprisingly durable. You retain your natural EV, and gain bonuses to both EV and AC. Even though Dragon Form has 150% health, because it is giant, you lose EV in the process.

Like Dragon Form, Storm Form benefits greatly from support magic such as Ozocubu's Armour and Manifold Assault.
