"Gods help us, they come from all sides!" you shout. Reginold does not answer as he works his bow. "Thrum,""thrum," goes the string.
You run from wall to wall, burning the goblins with your spells as they struggle to climb up. Their burning corpses provide good light for Reginold to shoot other goblins nearby.
You smile to yourself. You're really on a roll!
Gods, I HATE goblins, you think.
Unfortunately, the two of you cannot be everywhere at once, and soon several of the goblins have scaled the far wall. Two have dropped down into the courtyard while another charges upon the rickety battlement walkway toward you. Others are already scuttling over the walls like cockroaches.
