This is usually the first place many raiders will want to hit when they start raiding in kunark. However some bypass this area and hit the Protector's Realm because of the 4 easy skeleton mobs. Tairiza The Widow Mistress is not a particularly difficult creature, but isn't easy either if you do not have a solid well built group together.

The Drachnids are easy creatures, but have a timeable stun effect that is an AoE/Raid Wide based AoE. The stun lasts from 4-6 seconds and can be particularly nasty if you are not prepared for it. Skeletons are more problematic than the Drachnids because they cast a fear based AoE/RWAoE. When facing skeletons you will want to have your raid party members Shift+R to put them into walk mode and press C to put them into crouch if they are particularly close to the creature. If your party has over 50-60k dps these creatures will be a breeze to kill.

Progressing through the zone you will need to head up the hallway then kill the creatures in the left hallway then the right hallway or vice versa. As for facing the Spidermistress there are two raid strategies that you can follow.

First strategy is to setup the Main Tank against one wall and have the raid force on the opposite side. The second strategy is to carefully sneak in on the left side as close to the wall as possible avoiding the Widow Mistress's line of sight. Once everyone is inside this area have the MT setup against a blue jarr and the main raid force near the statue in the back. Either strategy is viable, but requires 1 group of the raidforce to switch constantly between doing damage on The Mistress and killing the webs that form on your party members.

The webs will continously suck life out of your party members that are webbed and will permanently stun them. Some suggest using the voice chat to shout out i'm webbed while others suggest using a programmed macro key spamming "i'm Webbed". Either works, but you must get the web off of the target person within 3-5 seconds. Webs usually occur every 13-14 seconds or sooner so be prepared.

When the Widow Mistress hits 28-40% health she will start calling for trios of heroic ^^^ spiders. You will need to get these off of the MT as quickly as possibly and either mezz them or get them onto another tank. Having these spiders spawn makes it very difficult to deal with this mob, but if you have very high DPS you can burn down the Widow Mistress and deal with the 6-9 spiders that you have left. If you have a Shadowknight in the group Death March can help out with the first 3 adds.

As for classes you will want 3 clerics, atleast 1 shaman type in the main tank group and some druid classes. Wardens are particularly useful for burst healing and furies can help to augment the caster class.
