Serket

Notes:
 * Located around G/H-7 and H/I-6/7 on the underground floor (this map).
 * Spawns every 21-24 hours
 * Killable by 18 level 60 players
 * He has a really nasty AoE that Stuns and has a nasty Poison. You may want to bring Antidotes so the White Mages aren't overwhelmed by curing Poisons. If you're a bystander, you may want to stand very far away unless you can handle the damage from the AoE.
