Since nobody would be kind enough to write a answer I guessed I should answer it ok starting now....

Theres only one boss ( so far ) and his name is Shadow Vespid he is a protecter of shadow shards so you pretty much know he does not want you destroying Ka again.

You can only battle him if you have a Guardian Knight Trail Key or if your a Member and you buy the key.

Here are some tips I have for when you get up to the Shadow Vespid

1. Find a group of monkeys! Team up with other courageous knights to take on this menace.

2. Take out the spawners first! Getting rid of the spawners and then the monsters quickly cuts on extra threats, so you can focus on the main Shadow.

3. Distract the Vespid by being in a group! Make sure the highest level monkey distracts the Vespid so you can heal, stun him, or take out the Spawners, Shadows, or Shadow Shards.

4. Stun the vespid with the Crest Relic! It is the Vespids' weakness so stun him to heal, distract him, or unleash very strong damage with your best weaponry you have!

Hope you like my answer :3
