Fireball hits him for 8, then he throws it back for 6 at you. Sharing one deck with the enemy is a sneaky idea, and I love that his next move is always visible. Hmph, nicely done.
Thanks! Keep an eye on what you feed him, though: the Cursed Ring only stings you for 2, but if he throws it, it hits him for 5. Later foes pick their throws differently, so what worked on the Slime can backfire. If any of them feels unfair, tell me, I’d love to know.
