Pathfinder: The Red Crusade
Scroll of Winter Wind
If read aloud the reader’s right hand is infused with a deadly cold energy. Once the scroll is read it turns into snow and blows away.
For the next 12 hours they may launch Cone of Cold . This is a one-shot spell. CL = character level of the caster.
If it’s not used by the end of the 12th hour the reluctant caster suffers a Touch attack from the spell they held onto, dealing damage as described in the spell.
