Guild Wars 2

I’m confused on how guilds work; I go to the tab and all it does is say what the guilds are, theres no section to join guilds or anything, so how do I join guilds?

You have to be invited to an existing Guild or create your own.

What things are you looking for in a Guild? Asking aroung in map chat and talking to the recruiters that advertise on map chat would be a good start to find an existing one on your server.

When you receive an invite from a guild, the name of the guild will appear on your guild tab in the lower left. Click the name, then you click the join button.

Once you join a guild you need to represent it (click the represent button). You can join up to 5 guilds but can only represent one at a time. When you represent, you see guild chat, benefit from the guild’s buffs and earn influence towards that guild.

You have to get an invite or you can create your own guild by talking to an NPC in the major cities.
