Dragon scale

Dragon scales are used to build dragon armor and dragon sword.

Dragon scales may be acquired by :
 * Finding Purple portals that are underground or, rarely, on the surface
 * Opening fire chests in hell. To open the chest you must collect some fire orbs that are dropped from monsters in hell.
 * Opening random high level chests (like dungeon boss chests).
 * Beating the Fire dungeon's boss: the Hell Dragon.

Upgrading the armor or the sword require a lot of scales, you may need to generate some others worlds just to loot the fire chests, or defeat the Hell Dragon a large number of times.
