Steel dragon (POH)

A Steel dragon can be built in a player's Treasure Room with 10,000,000 coins. It is noticeably smaller than other steel dragons, and is currently the third most expensive item which can be built into a Player-owned house, exceeded only by the crystal throne and demonic throne. It requires level 95 construction to build, but it can be built as early as level 90 construction with a orange spicy stew's +5 boost. Adding this guardian to your dungeon for experience is NOT advised as it is about 0.0003162 experience per coin.

This steel dragon was not initially updated alongside other dragons when they were updated in 2010, having to wait until 2014 to receive their update.

Trivia

 * The steel dragon seems to be slightly weaker than the pit iron dragon, whilst also costing more to create.
