Also drops from Lost Soul in Behemoths Dominion —The preceding unsigned comment was added by Spillejenta (talk • contribs).
Because stun is lighting based, it doesn't work very well on Earth types. Stun could possibly be negated by all Earth monsters. Not very useful for the CoP fight with Ouryu because he is a Earth type and you are level capped.
I just farmed for the Stun at Behemoth's Dominion a while ago, so I can confirm its drop at that area. I used 60THF/30DNC with Treasure Hunter I & II and fought a total of 24 Lost Souls (12 WAR and 12 BLM). Only one of those skeletons dropped Stun. I'll update the drop rate on the Lost Soul page. --LordChocoSlime 17:20 October 29, 2011 (UTC)
I took out Beaucedine Glacier as a possible drop location for Goblin Reapers. I farmed them for about 4 hours, with no drop, went to Gustav Tunnel and got the drop on the 4th Reaper. If anyone finds Stun on the BG Goblins, feel free to add it back in. Don't want people wasting their time. Yzerman of Bahamut
