Here is a little preview of the new gaming system that RPG Source is currently crafting. These small scavengers live almost anywhere. They are skilled at combat with various small weapons.
Goblins are dumb, weak, ugly, but very quick.
They make good thieves, and some with a high intilect make good mages. Goblins usually travel in familly tribes of eight to a dozen goblins. The tribes are usually lead by a charismatic shaman or a goblin mage. Hit points are the number of damage points the thing can take before it dies. Armor Check is simply another name for armor class.
