Killed it like..... 30 times thanks. Shield bash doesn't stun.... not ffxi. Dont think I havent used it against him, I have, it doesn't stun (read description). All my gear is boss. 174 vit. 75mnd for mg def. It hits for a very random range, since its elemental and all, not physical (aka all your plate armors don't mean jack towards it). If you dont happen to have stoneskin up at the time, you'll get hit pretty hard. Even with obsess II (especially since it increases defense to the target, no mag def increase specified) you may or may not get slammed.
