Guilds

Guilds were the multiplayer integration in Dungeon Keeper. You could join a Guild upon completion of the guild building at Dungeon Heart level 5, or you could start your own for 200 gems though it was advisable for new players to join an existing guild.
==Overview==
Guilds could have up to 50 members. Members could each donate and withdraw units to defend the lair, as well as using them during raids on other lairs. There was a cool down time after withdrawing and donating, which increased with the level of your Guild Lair (not your guild).
For guilds to proceed to the next level (and obtain the relevant perk), it was necessary for guild members to complete guild objectives (visible in the guild screen). Once the required number of objectives had been reached (minion donation, attack/defend points, etc) guild members had to donate gold to unlock the perk (see table below). After that, it was back to completing objectives for the next level.
==Donations==
To have donated minions to your guild, the second tab on your guild screen was used. Players tapped the minions they wished to donate, and clicked the "Donate" button. Minions hadto travel to the guild, so would only appear after 10 minutes. There was a cool down time before you could donate more minions . The number of minions you could donate was fixed at 10 for any level. Donated minions did not retain their trained level (gained from your training room ). The maximum number of minions able to be housed at The Guild was 3,000.
To have donated gold to your guild, the first tab, which shows the guild member list, was used, and the "view perks" button was clicked. You would be taken to a new screen, and on the bottom you would see a "donate" button. It would have the current total of donations and the next target to reach the next perk unlock. This button would only be visible when it was time to donate - until then it would not be visible.
