Key Attribute: Agility.

The Stealth skill governs a character's ability to move silently and remain undetected. It allows characters to sneak past enemies, eavesdrop on conversations, lay ambushes, and avoid detection in hostile areas. A high Stealth skill represents expertise in techniques like hiding in shadows, muffling footsteps, using camouflage, and controlling breathing to minimize noise. Successful use of this skill enables characters to get the drop on foes, bypass obstacles unseen, and gather intelligence covertly.

Typically, you will use Stealth to Hide, but you can also use it when Keeping a Watch.
