Scorpio Armor
This armor is made from the treated carapace of a giant scorpion. You can benefit from the armor, as described below, even if you aren't attuned to it.
While wearing this armor, it doesn’t impose disadvantage on your Dexterity (Stealth) checks while you’re in dim light or darkness. However, your speed is reduced by 5 feet while you're in sunlight, as the armored husk recoils and constricts from it.
While attuned to this armor and wearing it, you have advantage on saving throws against poison. In addition, you can use a bonus action to close your eyes and speak the armor's command word. When you do, you create an instantaneous pulse of awareness around you, immediately alerting you to the presence and location of any creature within 30 feet of you that's on the ground as if you had tremorsense out to a range of 30 feet. Once the armor's command word has been used, it can't be used again until the next dusk.
The old captain took slow walks through the courtyard during training. While the newer troops would jest that his age was catching up to him, an attempt by one of them to sneak into the larder would prove otherwise. A swift fist from the veteran swung out at the recruit silently from around a darkened corner, forcing a shrill cry from their untrained lips. Word spread quickly, as it always did, and the stock would be left untouched until the next season's wave of recruits arrived.
