Guile - Midkemia Online Online Help

5.6.3 Guile

Guile is a measure of the cunning and stealthiness of a Rogue. Rogues build up Guile while they remain hidden, and can spend it to execute devastating and deadly sneak attacks. Guile is most strongly associated with the Subtlety skillset, whereas Fencing attacks utilize Guile much less frequently.

Guile is determined by your level and dexterity.
