Staff of the Tempest is a Skill in Divinity: Original Sin Enhanced Edition.
Launch a magical missile from your staff that deals 80% weapon damage. (Jahan Only)
Jahan's final offensive when pushed to the brink. Learned in the brutal hills of Tanaroth after a near-fatal encounter with Sourcerers, Jahan swore he'd never find himself caught without a spell up his sleeve. The better his staff, the better the damage.
