Stealth and Perception

Stealth on Risenholm works a little differently to how it operates normally in Neverwinter Nights.

1. 1. How it works

When a character (the sneak) goes into stealth mode, every round they roll their stealth skill, and those around them (the spotters) roll their perception. This happens twice: once to determine if the sneak is seen (visual), and once to determine if they are heard (audible).

If a spotter's perception roll beats the sneak's stealth roll, the sneak is not immediately revealed. Instead, the spotter is put on alert for 2 rounds. The sneak will see the spotter's perception icon change from a closed eye to a half-open one, and an orange circle with a radius of 4m will appear around the alerted spotter. Only the sneak can see this circle.

If this circle appears while the sneak is within 4m of the spotter, then the sneak is given 1 round to get out of circle. Otherwise, the instant the circle intersects with the sneak, they are immediately revealed to the spotter.

If the spotter's perception roll beats the sneak's stealth roll while the spotter is already alert, a white circle with a radius of 4m will appear around the sneak. This indicates something has subconsciously drawn the spotter's attention to the general area where the sneak is. If this sneak leaves this white circle, they are immediately revealed.

The sneak will see open eyes over the heads of spotter who have detected them, a half-open eye for spotters who are alert but haven't detected them, and a closed eye for spotters who have not detected them, and are not on alert.

If a spotter's perception is 20 more than the sneak's hide, then the sneak is detected immediately.

1. 1. Stealth modifiers

Neverwinter Nights will give characters various bonuses and penalties to their rolls depending on their situation and environment.

1. 1. 1. General perception rolls

• If the spotter is in combat, they gain -10 to their perception rolls.
• If the spotter is standing still, they gain +5 to their perception rolls.
• If the sneak is standing still, they gain +5 to their stealth rolls.

1. 1. 1. Visual perception rolls

• If the sneak is in the back arc of the spotter, they gain +5 to their stealth rolls.
• If it is night time, then the sneak gains +5 to their stealth rolls, unless they have a light source on them.
• If it is night time and the sneak has a light source on them, they gain -10 to their stealth rolls.
• The sneak gains an addition +1 to their stealth roll for every 3m between them and the spotter.

1. 1. 1. Audible perception rolls

• The sneak gains +5 to stealth for every 40cm of object (including creatures) between listener and target in outdoor areas.
• The sneak gains +2 to their roll if the line of sight is blocked and the target is within 4 tiles in indoor areas.
