The Savage Beast of Horros is an augment spell with a range of 12" and is cast on a friendly character, which can be the Wizard himself. The model gains +3 Strength and +3 Attacks until the start of the caster's next Magic phase. The Wizard can choose to instead have his spell target all friendly characters within 12" (including himself). If he does so, the casting value is increased to 20+.
