Hmph. A Shek does not surrender to defeat so easily. Today, we will be the ones who stand. There will be blood!
— Band of Bones
Shek Challengers is an Event that can trigger if the Player has defeated the Raid or Shek Challengers events. It cannot trigger if Tora the Fearless, Esata the Stone Golem, the Bugmaster, or the Holy Lord Phoenix have been killed or captured.
One the conditions have been fulfilled, the Band of Bones will send an assault to the player's Base. This assault will consist of 3-6 squads, each made up of 4-8 Band of Bones.
When the assault arrives, the War Leader will give a short speech, then order the attack to begin, attacking gates and characters, and liberating captives. If the assault is victorious, the assault party will occupy the base, inhabiting it until forcibly removed, in addition to the Raid event triggering in 200-300 hours. If the assault is defeated, the Shek Challengers event will trigger again in 90-120 hours.
