Huge spider

The huge spider is a creature found in the Oubliette or Dungeon rooms of a player-owned house. It requires 86 Construction, gives 447 experience, and costs 200,000 coins to make. It will attack players inside the room but will give no experience when killed. It will initially try to attack players with melee, but if it is attacked first or a player attacks it from a distance, it will switch to ranged attacks.
