Stances
Guard
Safe no-income stance. No ambush. No gather. No heal.
Guard is the safe no-income stance. Hubs never need it. Use it in the wild when you refuse ambush risk and do not want gather income.
Guard never ambushes. Guard never gathers. Guard does not heal.
A leftover timed Guard activity (from an older CTA) still resolves for 40 XP if one is in flight. There is no hub button to start a new one.
Rated PvP treats a guarding defender as the toughest target. See PvP stance.
