Interesting tidbit tonight: I moved to Ulli's area to kill statues. Out of 50 kills, 5 raxa dropped. Mythril ore seemed to take a steep dive in drop rate with only 10 dropping. Shards were about normal with 5. Diorite 3(which is about normal for this spot imo, it's where I did most of my farming before but I chose the other area for more kills and no downtime waiting for repops for the purpose of this testing) Ulli is the last spot I know for certain that raxa were dropping so I moved there.

If these drop rates hold up then I'm not real sure what to do. It gives me a headache just considering that the two spots for them have different rates but for now I'm going to hang around Ulli's area and see what I get out of raxa drops. Old spot 0/370, new spot 5/50.
