Research - Goblins aren't especially bright, so don't expect to find one reading up on dark magic in the Library.
Dwarves - Goblins and dwarves have always hated each other and will usually single the other out in combat.
Gambling - In their downtime, goblins like to pour their hard-earned pay into the Casino.
If there's no battle to be fought, they will usually confine themselves to the Training Room.
Training - Goblins will make little time for anything else in the Dungeon.
Melee - Goblins possess no spells and no particular skills other than close-range combat.
In a group, however, goblins can be a formidable fighting force during the early segments of the campaign. Their primary role will be combat, although a lone goblin isn't going to prove to be very threatening. Appearing early on in the game, they are willing and eager to serve the Keeper's ambitions, although they do not have any particular specialty within the Dungeon. Goblins are a common type of creature in Dungeon Keeper 2.
