Grand Magister Valdis:
Thank you! As a matter of fact, there are several Raid bosses around here. Which one can you defeat?
Ah! Of course you don't have to do so personally. There is no rule that says a clan leader must take up the sword directly. You can order your clan members to defeat a Raid Boss, then bring me proof of the victory.
Daimon the White-Eyed
Hestia, Guardian Deity of the Hot Springs
