Memory:Rust monster

The rust monsters used to live in a lone mountain range in an outlying district of Ancardia. On one of their seasonal migrations, they were trapped in the Drakalor Chain by the forces of chaos. Unfortunately, their new home is very ill suited to their health. Their diet requires a complex cocktail of trace elements, minerals, ores and metals which are hard to find outside their native biotope. With their acid-dripping claws, they try to etch these substances from rock seams in the dungeons, but due to a very poor yield, they had to resort to attacking every adventurer with a promising looking backpack. Don't let them touch you; their corrosive grip will ruin your weapons and armor. Be generous and feed them, and they will soon calm down.
