Guild Wars 2

On wvw these buff , you need to have a keep or castle owned by your own guild?

Or is just a boost for all , and you can use it anytime without any keep , castle owned?

Thnx, for answers.

The guild buff works for everyone in your guild for 24h.

There’s three different kind of Guild buffs.

Banners: Anyone who clicks it gets the buff
Guild buffs: Everyone in the guild gets the buff (In this case the 10% PvP influence)
Fort buffs: Everyone in the vicinity of a WvW objective claimed by your guild receives the buffs
