+ | Before going in, I advised having Full chemical protection and anti knockback gear as monsters inside can break your gears easily and keeps on knocking you back. Anti boss items such as alice card is useful here as all mobs here are boss types. You cannot status them or knock them back either. Anti demi human items could also work and is much easier to stack. A normal 35% resist headgear and thara frog card on shield is good enough to be quite tanky here. You can use Yggdrasil Berry here but not yggdrasil leaf. You can re enter if you die. Avoid re organizing the party though as it usually cause bug issues. In the entrance you'll be greeted immediately by the monsters. You better go inside with the tanker and mob cleaner first. Royal Guards are best candidate for this as they can tank and clean monsters inside using grandcross with the simplest build. Proceed to Arqa Barrier located at the south east of the map. | ||
+ | |||
+ | ==== Arqa Barrier: ==== | ||
+ | |||
+ | Unseal the Arqa Barrier. The Arqa barrier can be opened by the leader with Heretic Ring. If you are having trouble clicking the barrier try to click the 2nd or 3rd one until it pop up. Go until you reach Arqa Guardian. It's a rotating stone. Click it and it will help you regroup with your members. (This is currently bugged) | ||
+ | |||
+ | [[File:Arqa.png|thumb|center]] | ||
+ | |||
+ | |||
+ | ==== Tyrant Cecil (MVP Room) ==== | ||
+ | |||
+ | Try to make your tanker move first. Clean the mobs around you and proceed to defeat Tyrant Cecil. Tyrant Cecil is a wind element monsters, using earth element is the best way to kill it. This monster can change element to Water, Holy and Ghost element when his HP fall at 70%/40%/10% respectively. The most effective class in killing this is an RK class using spiral pierce. But you can also try GX or just force it with RG using Grandcross/lifesteal until it die. Once you defeat Tyrant Cecil clear your way to Tziah Barrier. | ||
+ | |||
+ | ==== Tziah Barrier/Deceiful Kathyrene Room ==== | ||
+ | |||
+ | Tziah Barrier need any member with 6k kills, as far as i know you can open it even if you aren't the leader but I don't advise it as it might cause an issue in your run. Better open this with your leader. Once you open Tziah barrier you can proceed to open Cocytus Soul Crystal and it will summon Deceitful Kathyrene. Deceitful Kathyrene is a Ghost Element monsters. Items like freeza hat that can endow your weapon with ghost element is one of the most useful item in defeating her. This monster can change element to any element, Holy and Ghost element when his HP fall at 70%/40%/10% respectively. GX and RK are still the one I'll recommend in killing this. RG is not bad too. After defeating Deceitful move towards Thebel Barrier located at Southwest area of the map. | ||
+ | |||
+ | ==== Thebel Barrier ==== | ||
+ | |||
+ | Unseal thebel Barrier. nThe leader should have cleared at least once the endless dungeon instance (defeated naght sieger and talk to the npc there) and nydhoggur instance (defeated the dragon). Clean the mob and talk to the Thebel Guardian. Similar to Arqa Guardian | ||
+ | |||
+ | ==== Vengeful Eremes (MVP Room) ==== | ||
+ | |||
+ | Pretty much similar to what you did in in Tyrant Cecil room, clean the mobs and proceed to kill Vengeful eremes. Vengeful Eremes can deal massive amount of damage if you prolong the fight. Try your best to kill this otherwise he will have EDP and be on full power up buff which will make him a bit harder to kill. Vengeful Eremes is a poison lv 4 boss and the only thing effective against lv. 4 poison is holy attack. You might need to bring Aspersio scroll. Or just use neutral element. This monster can change element to Wind, Holy and Ghost element when his HP fall at 70%/40%/10% respectively. The best one in clearing this are royal guards. But you can still use the old method of using a champion with steel body as tank and GX or RK as killer. Using alarm card is useful here if you aren't using AOE's as vengeful eremes can go invisible while attacking you. After you defeated vengeful eremes, clear your way to Soul Crystal Empyrean room/Obssessive Margaretha Room. | ||
+ | |||
+ | ==== Soul Crystal Empyrean/Obssessive Margaretha (MVP Room) ==== | ||
+ | |||
+ | Make sure to clear the mobs first in this room. Summon Obssessive Margaretha and defeat her, Be careful of her skill "Turn Undead Armor", she can cast it on you and use a lot of powerful holy attacks. She is Holy Lv. 4. So cursed water is really helpful here. This monster can change element to Water, Holy and Ghost element when his HP fall at 70%/40%/10% respectively. After killing her unseal Adamah Barrier | ||
+ | |||
+ | |||
+ | ==== Adamah Barrier/Furious Seyren (MVP Room) ==== | ||
+ | |||
+ | Clear your way until you see the Adamah Guardian similar to Tyrant Cecil and Vengeful Eremes, go inside through it and clear the mobs. Furious Seyren is one of the most powerful MVP here. He can deal an extremely high amount of damage especially when his HP goes down to 20% where he normally use EDP too. So try your best to kill him as fast as possible. He is Fire element so water element is the best against him. This monster can change element to Holy and Ghost element when his HP fall at 40%/25% respectively. Once you clear him you can clear your way to Crazed Howard Room located at North West of the map. | ||
+ | |||
+ | ==== Yabbashah Barrier/Crazed Howard (MVP Room) ==== | ||
+ | |||
+ | The requirement for yabbashah is killing specific type of monsters. But they have similar names with normal monsters around the map so if you can't still open it just keep on clearing all the mobs you can see around the hallway. Inside the MVP room, do the same thing you did with other mvp rooms, clear and kill the MVP. Crazed Howard is a water element boss, wind elemental scroll is the best thing to use here. This monster can change element to Earth, Holy and Ghost element when his HP fall at 70%/40%/30% HP respectively. After killing it, you can now proceed to Monad Barrier (north) and clear your way to Tiamat Room. | ||
+ | |||
+ | === Eternity Passage Tiamat (Final Boss Room) === | ||
+ | |||
+ | [[File:1ab.png|thumb|center]] | ||
+ | |||
+ | |||
+ | The Eternity Passage is located at the north of the map. You can find it inside the Monad Barrier room Similar to the Tyrant Cecil room, you will still need to clear some mobs inside before you should summon Tiamat. Tiamat can be summoned through the eternity passage located inside the final room. | ||
+ | |||
+ | [[File:2ab.jpg|thumb|center]] | ||
+ | |||
+ | |||
+ | Tiamat is a pretty strong boss especially with Esma that can easily eat your HP But there are few ways to tank him; 1. Steel Body, 2. 100% Magic Reflect. | ||

Entrance:
Before going in, I advised having Full chemical protection and anti knockback gear as monsters inside can break your gears easily and keeps on knocking you back. Anti boss items such as alice card is useful here as all mobs here are boss types. You cannot status them or knock them back either. Anti demi human items could also work and is much easier to stack. A normal 35% resist headgear and thara frog card on shield is good enough to be quite tanky here. You can use Yggdrasil Berry here but not yggdrasil leaf. You can re enter if you die. Avoid re organizing the party though as it usually cause bug issues. In the entrance you'll be greeted immediately by the monsters. You better go inside with the tanker and mob cleaner first. Royal Guards are best candidate for this as they can tank and clean monsters inside using grandcross with the simplest build. Proceed to Arqa Barrier located at the south east of the map.
Arqa Barrier:
Unseal the Arqa Barrier. The Arqa barrier can be opened by the leader with Heretic Ring. If you are having trouble clicking the barrier try to click the 2nd or 3rd one until it pop up. Go until you reach Arqa Guardian. It's a rotating stone. Click it and it will help you regroup with your members. (This is currently bugged)
Tyrant Cecil (MVP Room)
Try to make your tanker move first. Clean the mobs around you and proceed to defeat Tyrant Cecil. Tyrant Cecil is a wind element monsters, using earth element is the best way to kill it. This monster can change element to Water, Holy and Ghost element when his HP fall at 70%/40%/10% respectively. The most effective class in killing this is an RK class using spiral pierce. But you can also try GX or just force it with RG using Grandcross/lifesteal until it die. Once you defeat Tyrant Cecil clear your way to Tziah Barrier.
Tziah Barrier/Deceiful Kathyrene Room
Tziah Barrier need any member with 6k kills, as far as i know you can open it even if you aren't the leader but I don't advise it as it might cause an issue in your run. Better open this with your leader. Once you open Tziah barrier you can proceed to open Cocytus Soul Crystal and it will summon Deceitful Kathyrene. Deceitful Kathyrene is a Ghost Element monsters. Items like freeza hat that can endow your weapon with ghost element is one of the most useful item in defeating her. This monster can change element to any element, Holy and Ghost element when his HP fall at 70%/40%/10% respectively. GX and RK are still the one I'll recommend in killing this. RG is not bad too. After defeating Deceitful move towards Thebel Barrier located at Southwest area of the map.
Thebel Barrier
Unseal thebel Barrier. nThe leader should have cleared at least once the endless dungeon instance (defeated naght sieger and talk to the npc there) and nydhoggur instance (defeated the dragon). Clean the mob and talk to the Thebel Guardian. Similar to Arqa Guardian
Vengeful Eremes (MVP Room)
Pretty much similar to what you did in in Tyrant Cecil room, clean the mobs and proceed to kill Vengeful eremes. Vengeful Eremes can deal massive amount of damage if you prolong the fight. Try your best to kill this otherwise he will have EDP and be on full power up buff which will make him a bit harder to kill. Vengeful Eremes is a poison lv 4 boss and the only thing effective against lv. 4 poison is holy attack. You might need to bring Aspersio scroll. Or just use neutral element. This monster can change element to Wind, Holy and Ghost element when his HP fall at 70%/40%/10% respectively. The best one in clearing this are royal guards. But you can still use the old method of using a champion with steel body as tank and GX or RK as killer. Using alarm card is useful here if you aren't using AOE's as vengeful eremes can go invisible while attacking you. After you defeated vengeful eremes, clear your way to Soul Crystal Empyrean room/Obssessive Margaretha Room.
Soul Crystal Empyrean/Obssessive Margaretha (MVP Room)
Make sure to clear the mobs first in this room. Summon Obssessive Margaretha and defeat her, Be careful of her skill "Turn Undead Armor", she can cast it on you and use a lot of powerful holy attacks. She is Holy Lv. 4. So cursed water is really helpful here. This monster can change element to Water, Holy and Ghost element when his HP fall at 70%/40%/10% respectively. After killing her unseal Adamah Barrier
Adamah Barrier/Furious Seyren (MVP Room)
Clear your way until you see the Adamah Guardian similar to Tyrant Cecil and Vengeful Eremes, go inside through it and clear the mobs. Furious Seyren is one of the most powerful MVP here. He can deal an extremely high amount of damage especially when his HP goes down to 20% where he normally use EDP too. So try your best to kill him as fast as possible. He is Fire element so water element is the best against him. This monster can change element to Holy and Ghost element when his HP fall at 40%/25% respectively. Once you clear him you can clear your way to Crazed Howard Room located at North West of the map.
Yabbashah Barrier/Crazed Howard (MVP Room)
The requirement for yabbashah is killing specific type of monsters. But they have similar names with normal monsters around the map so if you can't still open it just keep on clearing all the mobs you can see around the hallway. Inside the MVP room, do the same thing you did with other mvp rooms, clear and kill the MVP. Crazed Howard is a water element boss, wind elemental scroll is the best thing to use here. This monster can change element to Earth, Holy and Ghost element when his HP fall at 70%/40%/30% HP respectively. After killing it, you can now proceed to Monad Barrier (north) and clear your way to Tiamat Room.
Eternity Passage Tiamat (Final Boss Room)
The Eternity Passage is located at the north of the map. You can find it inside the Monad Barrier room Similar to the Tyrant Cecil room, you will still need to clear some mobs inside before you should summon Tiamat. Tiamat can be summoned through the eternity passage located inside the final room.
Tiamat is a pretty strong boss especially with Esma that can easily eat your HP But there are few ways to tank him; 1. Steel Body, 2. 100% Magic Reflect.
If you can tank Tiamat it's only a matter time to kill him. There are some popular way to kill tiamat.
1. Tanker + RK Spiral 2. Tanker + RK Spiral + SL 3. Tanker + Crit Type GX 4. Solo RG Reflect type
I am not going to give the builds as that will only make this guide longer, I prefer giving a general guide that players can use to study themselves.This should conclude it.
Goodluck and have fun experimenting. Or just ask someone else for their builds.
