This mob also drops an item called a Chameleon Diamond. It's an EX item that seems to stack. I just started exploring farming spots today with my 63 Thf and happened to get this drop.
Anyone else think Gigas look weird anywhere but Qufim/Delkfutt/anywhere cold? I just think these guys belong up north. Saw one in Korroloka on the way to Rabao for the first time, makes me wonder how he got in there...
