Guild Cataclysm Dungeon Hero

you need 3/5 party members to be from your guild. guild members can be of any level as long as they are all present in the instance (but they do not have to be in combat with the final boss).

You need three characters from the same guild inside the dungeon. They do not need to all be in combat with the boss.

You can tell if you're a guild group because the little flag on the minimap will change from a skull with a 5 under it to show your guild tabard symbol with a skull and 5 on the bottom.

This can be done with only two accounts if one of the accounts has two characters in the guild.

1. Have one player invite a second player in the guild to the group.
2. Have second player relog to a different character, have first player invite that character to the group too.
3. Run all three characters to the dungeon and enter. (Make sure it's set to Heroic.)
4. Clear to the final boss using the first two characters.
5. Alt-F4 on the second player, then quickly reopen the game and log into the second character.
6. As soon as the flag on the minimap changes to the guild group flag, kill the boss using the first character.

If you purchased the reward and then leave the guild, the reward gets returned to the guild.

Absolutely false. http://forums.worldofwarcraft.com/thread.html?topicId=27497533809&pageNo=1&sid=2000#3 Mumper said:

You keep all rewards that you earn via the new guild system. Some require a specific amount of guild rep to use, but we never take them away.
