Scratch your back !
What Abgral used to scratch his back was actually a Magic Relic. Hoodoo's Wand! Its power can influence Badass's power in combat. But its use requires sacrifice. In fact, you must discard a Leather Resource card, whatever its value, to use the Hoodoo Wand.
It's all well and good to want to recruit Abgral, but you'll have to measure yourself against him. Do you feel up to it?
Be Bad, Be Tough, Be Orc!
