Stealth

From NWNWiki

Stealth Mode: The hide and move silently skills are part of the stealth modal action. Select the Stealth option from the Special Abilities heading in the radial menu. Characters in stealth mode cannot run, and move slower than a normal walk if also encumbered or in detect mode.

When frightened (e.g. by the fear spell) while in stealth mode, a character will not leave stealth mode.

For factors affecting a character's ability to successfully use stealth mode, see listen and spot.
