Level 12 Normal Boss : A cruel eastern monster who feeds on humans
is LVL 12, the Kamaitachi. This monster has a 89.4M power and is also classified as a hard monster by Evony standards. They will use 35 stamina. Evony suggests that you can beat these bosses with 600,000 T12 cavalry troops (to get 0 wounded it will take 700,000 T13). My other reference suggests 736,000 T11 cavalry (over 17,000 wounded), or 1M T12 (or 1.1M T13) cavalry troops for no wounded. The rewards include the level 12 boss chest (contains gold, material chest and 100K of each of the four resources), spiritual beast exp, Dragon scroll chest (holds a scroll used to craft Dragon equipment), artwork fragment chest and an epic (LVL 5) treasure map. Everyone in your alliance will receive a Senior Alliance Boss package, same as the Griffin and Ifrit.
