A team is up to four heroes. Experience is shared with team-mates who are near enough to see the kill, so a team that scatters across the map stops sharing.
You keep a friends list and an enemies list, and you can inspect any hero to see what they are wearing.
Founding a guild takes level 15 and 1,000,000 gold. A guild holds up to 50 members across three ranks — leader, deputy and member — with a shared fund and a bulletin the leader writes. Guilds can ally with and declare on one another.
Guild War is scheduled on Saturdays from 20:00 to 23:00 server time, with an advance announcement and a five-minute countdown. Guilds fight over the pole and gates in the Guild Area. Taking the pole transfers 10% of the former holder’s guild fund; holding it when the war ends pays 30,000,000 gold. The holding guild’s leader can pay from its fund to heal the pole. Check in-game announcements for the active schedule.
Two players can trade face to face, gold and items both. For selling without a buyer present there is the Market, which carries 144 numbered stall pitches — claim an empty one, stock it, set your prices, and it sells while you stand there. Packing up asks you to confirm first.
The warehouse keeps items and gold you do not want to carry, and what is banked is safe.
