Scattered into Shadow

Speak with brutus, you will receive 3 keyitem “Aquaflora”, you have to take them to 3 pools in Fei'yin.

The pools can be examined in any order, but the pool at F-5 will always be the one to spawn ghost. In Fei'yin (1st map), you will need to go to G-9 or E-7 to get to the underground area.

Go inspect 2 pools, located at H-5, and H-8 which are on the way to the last pool at F-5.

When you inspect the last pool at F-5, Dabotz's Ghost will spawn. Recommended: at least 2 Lv 75's

I did this way back when I was doing 5-1. My party of 6 that did 5-1 with me had to escape because he was too hard. I came back with 4 or 5 65's and kicked his butt. Be sure to either drag the ghost into the hallway or clear the room and fight him there. Clear hallway of any bats and hang in.

After you kill him inspect the pool again for a cut-scene.

Now you need to Now go back and speak to Brutus.

Now head to Castle Oztroja, and get a Chest Key, then find a Chest to get a Beast Collar. For me a year ago, this was extremly hard (not getting the key, but finding the chest). It took 2-3 hours to find that darn chest. I heard its much easier now though, so maybe just bad luck.

Trade the Collar to the Wandering Monkey Tebhi (near the area where you go to the Torch for Mission 10). Report back to Brutus for your reward.
