Deep in the Yafaem Saltmoor lie the ruins of the fabled city of Mhach─a civilization of the Fifth Astral Era whose prosperity was built upon unparalleled magicks of destruction. It is to this ancient edifice, and its vaults of occult secrets, that you and the Redbills plan your next foray.
You expect to encounter voidsent─the same terrible beings that grounded Radlia and her crew─but on your path to retrieve a relic of incalculable power, can you prevail over the unfettered miseries of the Weeping City itself?

Bosses

Arachne Eve

The Weeping City of Mhach Guide Part One

The Weeping City of Mhach Guide Part Two

After some damage, the Arachne Eve will bring the alliances up into her web.

One alliance must find and kill a small spider add to tear a hole in the web and drop down to the level below. Then tear down the pillars that surround the arena and kill the adds.
Meanwhile, the others on the web must absorb the blue orbs and kill purple orbs to avoid buffing the boss.
After all the pillars are destroyed, the boss and all alliance members will fall to ground level.

When the boss casts a tornado-like AoE that pulls everyone to the center of the room, stand on webs on the ground to avoid being pulled.
When you see the boss cast Fond Affeared (eye), look away or you get a Feared debuff that stuns you for 10 seconds.

Forgall

(Mega Death) - stand in the green puddle to gain a stack of Gradual Zombification - this lets you avoid getting killed instantly by Mega Death

Green puddles give you a stack of Gradual Zombification - if you get multiple stacks you will turn into a zombie and attack your allies

(Void Call) - Forgall will summon three adds - burn down the Summoned Succubus first and stun her Beguiling Mist

Another add (Summoned Haagenti) will also cast Mortal Gaze - if you don't face away from the add at the end of this cast, the Doom debuff will be applied and must be cleansed by healers.
Stack up for heals after the adds die

(Brand of the Fallen) - Throughout the fight, players will periodically be marked with red arrows - all marked players must group together to avoid large damage and Toad status.

(Hell Wind) - healers need to mass heal

(Punishing Ray) One person needs to stand in each red pillar

Ozma

Sphere form: Ozma begins in sphere form, which is the "safe" form. During this form he will cast delayed Meteor spells that display their AoE in a purple circle, marking players - players should try to spread out the damage from these as much as possible to avoid party members being hit by multiple meteors. Multiple meteors overlapping their blast radius will deal immense damage. Usually these are placed to the back of the rectangular platform, and to the round part on your left.
Pyramid form: In pyramid form Ozma will cast a single high-damage AoE on the long rectangular platforms when he finishes transforming, so players should move to the circular sections. During this phase Acceleration Bomb can be applied to players, and deals heavy AoE damage to players that move or act when it expires. Additionally, members are randomly hit by a weak AoE that places a powerful stacking DoT on all members hit. Healers should cleanse these.
Cube form: At the beginning of cube form, Ozma will cast a large donut shaped AoE, causing moderate damage to anyone not standing close to him on the rectangular platform and apply Vulnerability stacks. Damaging orbs will orbit the platform, and cleaving laser blasts will target the tanks. When he casts the tornado, make sure the alliance is standing on one corner to Ozma and the tank on the other one. DPS and healers should stand on the rectangular platforms out of the path of the orbs, while tanks move to the circular sections to soak lasers and orbs. During this phase, he will also cast Holy, which deals a moderate amount of damage and knocks players a small distance away from Ozma. It is best to stand on the edge of the platform close to him to dodge the spheres and not fall off. Acceleration Bomb can also be applied during this phase.
After taking some damage, Ozma will cast Black Hole and suck the party into him. There are two phases to this part of the fight. First, the parties will be separated into three platforms with Atomos enemies on them, which should be focused down immediately. Each party will have to stand in a circle that makes another party's Atomos vulnerable to damage (the same as the Atomos fight in Labyrinth of the Ancients). After the Atomos enemies are defeated, finish off the last of the adds and jump down to fight Ozma's shadow. During this phase, face away from the boss when he casts Assimilation, and if you are marked with a meteor run to a corner to avoid unnecessary raid damage. It's worth noting that this entire phase is a moderate DPS check - if players are inside Ozma for too long, Doomsday will finish casting, wiping the raid.
After defeating the shadow, a portal will open that returns you to the main platform. The meteor effect from sphere form will return, but with more AoEs; one possible strategy is to have two people from each alliance stand in the back corners of the rectangular platforms, with the remaining players placing their AoE's anywhere that doesn't threaten other alliances.

Rinse and repeat.

General Notes:

You can fall off so be careful
Meteors (Black AOEs) - move these away from the group and don't stack them
- Place one Meteor in the back of your platform, the other on the ring to your left
- Singularity Fragment adds spawn where they land
Acceleration Bomb - As the debuff runs out, a die will appear above your head and count down. If you are in the middle of any actions (including walking) when the debuff wears off, the bomb explodes for high damage and a short stun as you're launched into the air.

Ozma's Forms:

Sphere - safest form - he casts Meteor in this form
Pyramid - he opens with a high damage attack on the long platform, move to the ring when he transforms to avoid this
- He'll apply Bleed to people, spread out to keep it from spreading
Cube - stick close to him to avoid knockback, tanks and healers soak orbs

Black Hole:

When you're sucked in, stand on the platform and burn Atmos
- Adds cast Paralyze III - stun this
Face away from the Ozma's Shade when he casts Assimilation
If you take too long you'll wipe to Doomsday

Calofisteri

Haircut is always where her hair's blade is visually represented on her model (bleed can be cleansed. Strong bleed). The boss' main attacks cause a cleave on the side of her blade. Move far away from extension telegraphs as they pull you in even when you're not standing on them. If the adds spawning from extension are not killed in time, the person trapped inside will die, and it will suck another person in and repeat. Focus these ASAP.

There will be a phase where she summons multiple Bijous and Small Bijous. Focus the Small Bijous down first as they finish their Energize cast sooner, and then burn the Bijous. Every Energize cast powers up her next raidwide AoE and will wipe if she has too much damage.

When the axe and bulb flowers spawn, look for the axe flower and stay near them to avoid their donut AoE. The bulbs will cause for a damage and knockup under and around them. Depth Charge will make the boss charge towards the wall, usually follows with Haircut. Make sure to watch where her blade is and dodge Depth charge on her safe side. Reposition the boss afterwards.

Penetration will pull you towards the center if you're looking at the boss, and will push you away if you're not. Bulb flowers will spawn and you will be pushed into them if you don't stand on an open spot. Try to position yourself to be pushed towards the empty spots of the arena to avoid these. When 2 blade flowers spawn just move away from the center. Red markers on players is just like the Cloud of Darkness marker, periodically raining damaging blasts down upon the player's location, so just run away from everybody and keep running to dodge these.

Try to keep the boss around the middle of the arena, as it will often pick a side and do a huge AOE (the whole half of the area she is facing) that usually kill anyone caught in it. Don't tank her on the edge, as you might have just a tiny safe spot and will most likely result in a wipe.

When she stops and looks toward a direction get away from her front side and move to the middle, as after dealing damage straight ahead of her she'll do one of her deadly AOE.
