Stalking is a Non-Combat Activity that focuses a character’s capabilities with Stealth to ambush a living Creature using silence and camouflage. It relies on their other skills for context and is NEVER passive. A character cannot use both Camouflage and Silence aspects of stalking unless they move at maximum of half their normal movement rate. Characters can develop these types of actions as Accomplished Activity.
Armor with the Noticeable property makes this more difficult ( Disadvantage) – Rudimentary Armor & Basic Armor are most often this way.
The Observant trait can improve the chances of avoiding being stalked.
This Equipment/Feature is leveraged as part of the ENCumbrance system.
