Unless it has an extremely small aggro radius, I don't think this mob is aggressive. I walked past a couple as a level 76 without sneak or invisible. I just started playing again after a year+ hiatus and wasn't paying attention running through.--Sagerose 05:57, August 17, 2011 (UTC)
Correct this mob does NOT aggro at all, but it does link like a mofo lol. i tested this just about 5 min ago on my smn95/rdm. i was curious myself as to where a good spot for pulling one at a time was the cave was so packed with them. but managed to find a nice spot by the weapons at the very most north region of Ranguemont Pass to farm for the season stone and other Lv 95 genkai quest items.

Also would like to point out im still adding drops and rates and all other info i can possibly come up with on these bats since ive been in the cave 3 days straight searching for the last item i need for 95-99 Lv cap. Destrover 12:15, March 29, 2012 (EST)
To whoever is updating the drops with crystals, geodes and "nothing". these are drops with set rates for all monsters, and should not be included on the mob pages, also, geodes only drop during certain conditions.
