Gulg is a boss monster added by Witchery. Gulg and Mog are worshiped by Hobgoblins. Their worship can be exploited by redirecting it to a witch using a Statue of Hobgoblin Patron. Exploiting them too much may cause Mog and Gulg to be summoned. Using a Nether Star on the statue may make them take immediate notice to the exploitation.
Gulg has 400 ( × 200) health points. He will punch the player into the air and deal anywhere between 5 () to 18 () points of damage. The punches may launch the player high enough to cause fall damage. Slaying Gulg will typically drop a piece of chain armor, some Koboldite Nuggets, and Gulg's Gurdle.
Gulg and Mog receive damage resistance when near one another; the resistance is as follows:
Mog will always try to move closer to Gulg to exploit extra damage on targets Gulg sends flying. Gulg will deal 4 (), 8 (), or 12 () extra points of damage based on how close Mog is. His throwing will be much higher if they are closer together.
