Only used by members of the Gnole family when standing.
The Lobisons at (F-6) in Jugner Forest (S) seem to stand just about all the time.(69% moon phase and there were 4-5 standing up)
BLU/WAR with very high def (850+) and Terror Touch or Corrosive Ooze will take very little damage from Lobisons. BLU/WAR + a damage dealer, or NIN/WAR + BLU to stun is your best bet, although more damage dealers are helpful since they recover a lot of HP with their TP move.
Easily accessible with either Recall-Jugner, Jugner Maw, or using the campaign teleport and simply head west to the Maiden's Spring. Beware because the Lobisons have a fast re-spawn time.
The Fusty Gnoles around (H-7) of Xarcabard (S) are always standing, day or night.
