Scroll Obscuring Mist

All ranged attacks suffer -4 To Hit

This spell causes a dense fog to fill a 10′ cubic area which lasts for the duration of the room. It effectively renders all characters and monsters in the area obscured from ranged attacks. The effect of this spell reduces the To Hit chance for both player and monster via a targeted ranged attack. This means that all ranged weapons (i.e., bows, slings, or thrown weapons) and all targeted spells (e.g., scorching ray) receive the -4 penalty. Spells that automatically hit (e.g., magic missile) and melee attacks are not affected.
