Battleward

From publisher blurb: Shields Against Magic! With this Real Scroll from Kobold Press, you won't just tell your players they've found a battleward scroll -- you'll hand it to them! This beautifully hand-lettered one-page reference has the feel of a real magical item, with all of the information a player needs to use this life-saving defensive spell. Battleward is one of 733 new spells for the Pathfinder RPG found in the Deep Magic (Pathfinder) compendium, and one of the basic attack spells of the new Clockwork school found in that volume.
