Guild Raid Zone. Enter from door near Guild registar in [East Freeport] or [Qeynos Harbor]. Recomended that all raiders (from evil or good side) be in either EF or QH when zone is entered.
Quest: Kill Mother Znedari
Tactics: Get ready at the top at zone in (buffs, etc). Everyone go downstairs but stay inside tower, have the tank step outside and pull mobs in until the area around the tower is clear. Avoid using out-of-encounter AEs (blue background, etc) because they can hit mobs wandering around the tower and add. Once the tower area is clear, start pulling each mausoleum. There is a named in each with a couple guards. These named will memwipe and aggro a certain class frequently, calling out the name of the person they are going to attack. See map for the type of class each sister will aggro on memwiping. Healers include power healing, so enchanters should watch out on two mobs. Once all 4 sisters are killed, the "shield" around the Mother is gone and she can be attacked. It is best to approach from a nice open place where everyone can see each other (the tombstones can sometimes block casting for healers). She will also call adds during the fight, but there is a trick. Start off by focusing entirely on the Mother, and ignore her guards. Don't AE at all, as she seems to bug sometimes (or maybe it's scripted) to call adds faster when her guards are dead. She will memwipe and target ANYBODY in the raid, that includes anyone that revived up in the tower. DO NOT REVIVE, stay down and let a rezzer (pref paladin, necro or dirge) to rez you. Otherwise she can run off towards the tower, with the adds staying put, splitting the raid force. Better to stay dead the whole fight than risk wiping. Also, she can bug out if you wipe too often, and become non attackable. Thankfully this zone does not lock until you kill her (hopefully it stays that way).
Boss Specifics: Mother Znedari is a caster, warlock script. Casts a disease and a poison spell, melee's with crushing damage.
Reward: 1 Chest, seen 1-2 armor drops before. Also, this is the only zone that I've seen a rare harvest drop nearly once per raid. It drops off trash, in a wooden chest.
