The borg will use a wand of wonder in munchkin mode.
While in Munchkin Mode, before he leaves the stairs to fetch an object, he will do a Detect Monsters/Traps just to make sure no bad guys in lurking in the hallways.
For those not familiar with it, Munchkin Mode is when the borg will bounce on stairs and grab near by items. He will stair scum and sell items until about clevel 7. He uses the money to improve his starting equipment. It is kinda cheesey but it improve the survivability of early borgs. It can be turned off in the borg.txt file.
Mages wearing heavy armor and losing mana fixed.
