Goblin Box

The Goblin Box is a loot box with a distinctly goblin look. The silver version is cobbled together from odd hunks of silver-colored metal, with a goblin skull etched into the lid. A Silver Goblin Box is the reward for Boom!, an achievement for setting off an explosion big enough to shake the dungeon walls. The first one opened holds five sticks of dynamite, a lighter and a Goblin Pass. The pass takes the shape of the same goblin skull and, instead of going into the inventory, brands itself onto the forearm of the crawler who opens it, marking the jacket sleeve over it too.
