Many of these places raid for fun, for the sheer exhilaration that comes with battling with a particular opponent and having the chance to take certain items, but beware, as the room that One raids might just decide to raid that room right back and reclaim what was pilfered.
These are the sites that raid, as well as the particular rules One sets forth. Read these before You join a room as a Member Warrior AND before preparing to raid. A word of caution, though: Many of these rooms do not raid every single place on the list. Be sure to check with the Leader of the Room You are a Member of to find out who is eligible to be raided by order of the Council.
