They are vulnerable to both ranged attacks and magical spells, and classes wielding such implements can put down a Goblin before it ever reaches melee range. In the original game they appear to be genetically related to the games' Gnolls, and share the same sprite as them. When ported to the Nintendo Entertainment System however they were given their own sprite, appearing more demonic and sinister than their original counterparts.
