Ghost Leather Armor

While wearing this armor, you can speak its command word as a bonus action to move incorporeally for 1 round. You can move through other creatures and objects as if they were difficult terrain. You take 5 (1d10) force damage if you end your turn inside an object. You can use this ability a number of rounds per day equal to your level.

The breastplate and shoulder protectors of this armor are made of leather that has been stiffened by being boiled in oil. The rest of the armor is made of softer and more flexible materials.
