Player- heroes resort to STEALTH whenever they need to act in a furtive or secret way. The Skill includes hiding, moving quietly, and shadowing others. These activities often rely on quickness and precision, so a stealthy Player-hero combines practised caution with the ability to judge the right moment to take a chance. Hunters, burglars, and solitary fighters use STEALTH to prosper in their trade.

A successful STEALTH roll indicates that the hero has gone unnoticed, while failure almost certainly attracts unwanted attention. A superior success produces an outcome so flawless that it may even be impossible to notice the deed after the fact
