Thinking quickly Ajax throws a flask of oil at one of the goblin blockades followed quickly by Gynx igniting it with her magic. The group then used the distraction to escape in the other direction. They easily smash through the goblins and head back to Amvianda to recover from the ambush.
After their rest the party returns to the tomb, now much more cautious of goblin ambush. They discover some of the goblins recovering themselves in a makeshift barracks. They make quick work of these goblins and continue their exploration only to find the main goblin nest.
After a pitched battle the party finally rids the tomb of its goblin infestation.
