Divine Storm

Divine Storm is a spell in the standard spellbook. Casting it requires 60 Magic. It must be cast a total of 100 times inside the Mage Arena before it can be used elsewhere. The fastest method to do 100 casts is to wield a wand and orb/book whilst autocasting the spell for both mainhand and offhand.

Abilities do not count towards the 100 casts.

Trivia

 * The spell has replaced the three god spells—Saradomin Strike, Flames of Zamorak, Claws of Guthix—as well as their power-up spell, Charge.
