I dont understand the cave goblins. Are everyone of their people cave goblins = incompetent and clumpsy or is only the extra person (cave goblin marker)you started the game with affected by this? To me it seem strange to have this extra cave goblin marker instead of just using an extra personmarker.
There are only 5 person discs per color but Cave Goblins can have 6 of their own people. That's what the Cave Goblin marker is for. You can start with 3 person discs or 2 person discs and the Cave Goblin marker - doesn't matter. All Cave Goblins are incompetent and clumsy not just the card board marker.
