Caught an uncommon spawn at 6am realm time after finding nothing but poor spawns. I then battled another poor with a rare Desert Spider and got the Flawless Beast Battle-Stone from it! Not bad, means I can make it rare myself :D
Found one at 6pm UK time, weather was clear. I was waiting around for half an hour or so and got nothing so I started to kill the Thundering Exlies to pass the time (I killed them all) and 2 spawned, I got one poor and one uncommon. Maybe killing them does actually work.
