From publisher blurb:
Advantageous Abilities provides Game Masters a toolkit with which they can easily add feature abilities to monsters and NPCs, giving their NPCs an advantageous edge (or just a little role-playing fun).
Each product in this line has more than 15 themed feature abilities, and instructions that allow GMs to easily customize existing creatures or create all new foes.
Advantageous Abilities: Savage Abilities includes twenty abilities. Surprise your PCs with abilities like Battle Cry, or Blood Hungry, add a little flair with Smasher, or give them something to worry about with the Bloody Show ability. No matter your choice, this PDF is sure to make flavourful and effective NPCs.
