The Equipment Collector can be seen in the castle area randomly. He appears as a character with a weapon icon in a thought bubble above his head. Clicking on the Equipment Collector prompts a dialog in which the Equipment Collector tries to buy equipment from you.

NOTE:  You can no longer sell anything to the Equipment Collector.  It is a leftover NPC from an earlier version of the game.  You can only sell weapons and armor through your Items management screen.
