|[ dwarvish cloak|
Any cloak is better than a dwarvish or orcish cloak, but a dwarvish or orcish cloak is still better than nothing. Though it offers no AC when not enchanted, it still offers magic cancellation and protects any suit underneath from rust and destroy armor. If you test unknown scrolls by reading them, an orcish or dwarvish cloak can be useful as a throwaway cloak to catch destroy armor, after which you can put your regular cloak back on.
Non-lawful characters will likely run across dozens of these cloaks while exploring the Gnomish Mines. Collecting and then selling them can provide your character with some easy money relatively early in the game.
