Tonight PO trekked to Mamook to fight 1 of the 3 new beastman gods. Once we ran through the entire zone, and started fighting, it took us about 1hr to bring it down. It has very high defense, and magic resistance. It also blows up at less than 5%. We finally killed it and got 7 GIL and a title, lol. So, at this point, it's a worthless NM.
I read on BG that it dropped nothing for 1 LS, however we didn't know if the treasure pool was like Tiamat were it can drop nothing, or something good.
