Skeleton guard(oubliette)

Skeletons, called Bones when challenge mode is turned off, are undead guards which can be bought for an Oubliette or Dungeon with 50,000 coins and level 70 Construction. This level may be boosted by tea but not by the crystal saw, since no saw is required for the purchase. When purchased, it earns 223 experience. Despite being dungeon guards, they are not aggressive during challenge mode and will ignore players unless attacked.
