For perfect World players,here we will discussion the common tactics/strategies used on Twilight Temple boss .This is for squad mode though, not single, as single bosses are extremelly easy.If you are interested in the guide,please read it up.Hope the article can help you.

 

Chintien: Chronol
Physical Attack: 1228 - 3684
Magic Attack: 1842 - 5525
HP: 811.278
Always will spawn, need to kill him to open the gates for rest of dungeon. He is very easy and will use Earth Spells to attack you.

Lord of Percussion: Chronol
Physical Attack: 1588 - 4763
Magic Attack: 2381 - 7144
HP: 695.393
Always will spawn too. But this guy on the other hand, is different, on squad mode he will cast a Physical Damage Area of Effect spell every 10 seconds once his HP goes bellow 50% (around the "PER" of his name), and the range is so wide that you cant just heal from far. Usually the squads need to use blue bubble on this guy (to cut damage by half), or you are doomed to kill half the squad or more. Note aswell that the damage will start low, but the max damage will increase as his HP goes down, doing very high hits when he is about to die.
Besides that AoE attack, his only other attack is a Metal spell that he will cast constantly.
Note, on 1-1 (chronol), he will spawn on the middle of the dungeon, and the gate behind him will be closed.

Soulbanisher: Chronol
Physical Attack: 1249 - 3747
Magic Attack: 1873 - 5620
HP: 1.246.067
Only spawns on "HIGH" boss spawn, he will be at the start of the dungeon, unlike his proper room (1-2 and 1-3 spawn), will do no AoE attacks and is very easy, but has a lot of HP.
You will only see this boss when doing the Last Hope (final part of Wraith Ploy, lv70+ quest to travel time), he will be blocking your way to Vipenalt, but if you are sneaky, you can pass through him unnoticed.
Special Note: This boss will drop no materials.

Dimentora: Chronol
Doesnt spawn on this mode. Or rather saying, the gate is closed, but he probably doesnt even exist.

Vipenalt: Chronol
Physical Attack: 1249 - 3747
Magic Attack: 1873 - 5620
HP: 1.246.067
Only spawns on "HIGH" boss spawn. He will be on the room called as "Drum Room", east side of dungeon, just at the start. He isnt hard at all, hits very low but has a LOT of HP, so will take a while killing. You will need to kill him to complete the Last Hope quest.
Special Note: This boss will drop no materials.

 

Chintien: Dimensic
Physical Attack: 1398 - 4194
Magic Attack: 2097 - 6290
HP: 1.130.684
Always will spawn, need to kill him to open the gates for rest of dungeon. He is very easy and will use Earth Spells to attack you.

Lord of Percussion: Dimensic
Physical Attack: 2162 - 6484
Magic Attack: 3242 - 9725
HP: 857.511
Always will spawn too. Check the info on how to beat Chronol for his attacks. Only difference here is that he is on the so called "Drum Room", which is from East side of dungeon, opposite direction of "Chintien Room".
Just to remind, Physical AoE past 50% HP, be careful.

Soulbanisher: Dimensic
Physical Attack: 2129 - 6387
Magic Attack: 3193 - 9580
HP: 1.259.749
Only spawns on "HIGH" boss spawn. Similar to Lord of Percussion, he will cast a Physical Damage Area of Effect spell every 10 seconds once his HP goes bellow 50% (around the "BAN" of his name), and the range is so wide that you cant just heal from far. His attack is a lot stronger though, and not many can survive his last attacks, so Blue Bubble is a must here, the damage will start low, but the max damage will increase as his HP goes down, doing very high hits when he is about to die.
Besides that AoE attack, his only other attack is a Fire spell that he will cast constantly. I ADVISE you get a cleric with over 3k HP to bubble if you plan on killing this guy.
His room is just WEST from the first corridor with rolling balls (before the balls), past middle of dungeon.

Dimentora: Dimensic
Physical Attack: 1609 - 4826
Magic Attack: 2413 - 7238
HP: 2.478.280
Only spawns on "HIGH" boss spawn. First off, this guy has a LOT of HP, way more than any other bosses on this dungeon level, so be prepared for a long battle (10-20 minutes depending on your squad) and grab your mana pots/charms with you (for clerics and DDs).
This guy spawns on the end of the dungeon, on a big room i call as "Dimentora Arena", its a huge place just past all corridors with rolling balls. It has a few blue glass castles that disapear after a while fighting, do dont stand on top of them or you will be teleported to a random spot of the dungeon. Also, dont enter the glass area while it vanished, because it will appear back and you will get stuck inside.
Trick here is lure him away from the middle of room, into a corner, get the barb or herc to do this (anyone with high physical def works), so you can fight him in peace. Why? Because at 80% HP he will call for the "DaVinci" and 4 big guys will spawn on middle of room and roam there until the end of the battle.
Be extra careful when he mentions "007", will happen if the battle lasts over 10 minutes, his "aggro" will reset and if the DDs dont stop attacking, he will throw his AoE against the group.
About his AoE, it isnt a big deal, short range physical AoE centered on his target (around 10-15m), stay away from tanker and you wont get scratched from this fight. A single cleric can keep the tanker healed very well, no need for bubble, but you will need a lot of mana.

After you kill him, you can use the portal on the middle the room to get outside the Arena, you will be warped to near the corridor with the rolling balls, pay attention on minimap for patrols and enter the portal when they are gone. Keep going anti-clock wise and go north, until you reach "Snake Room" and kill the next boss.

Vipenalt: Dimensic
Physical Attack: 953 - 2858
Magic Attack: 1429 - 4287
HP: 1.303.861
Only spawns on "HIGH" boss spawn. If you followed my info above and got to this boss after killing Dimentora (or skipped him, but you are dumb), you will see this big green snake that looks like Empirean Slither from Tai Chi Shore.
All he does is cast Wood damage spells every few seconds, but any tanker can handle this. Be warned that past 50% HP, a few "clapping hands" will show EVERYWHERE inside his room, DO NOT RUN, they will not explode if you dont move (someone confirm me the condition of the explosions please). If you dont move, the hands wont explode, and only "bad side" of this is that the cleric mana regeneration will be cut to 25%, forcing him to spend more mana to keep healing.
 

Chintien: Substancia
Physical Attack 1571 - 4712
Magic Attack 2356 - 7067
HP 1.497.335
Always will spawn, need to kill him to open the gates for rest of dungeon. He is very easy and will use Earth Spells to attack you.

Lord of Percussion: Substancia
Physical Attack: 3229 - 9685
Magic Attack: 4842 - 14527
HP: 1.036.873
Always will spawn too. Check the info on how to beat Chronol/Substancia for his attacks. He is on the so called "Drum Room", which is from East side of dungeon, opposite direction of "Chintien Room".
Just to remind, Physical AoE past 50% HP, be careful. A lot stronger than previous one, as expected.

Soulbanisher: Substancia
Physical Attack: 3185 - 9554
Magic Attack: 4777 - 14330
HP: 1.526.201
Only spawns on "HIGH" boss spawn. Check the info on how to beat Substancia for his attacks.
You will need a even better cleric than before on this guy, as his physical attack is insane. Not many people do this guy even at lvs 80-89. His magic attack also will hit the barbarian charm a lot, so be prepared, dont go with a barbarian without charm there or you risk getting him killed on 2 shots (unless you bubble since the start of battle).
Just to remind, Physical AoE past 50% HP, be careful.
His room is just WEST from the first corridor with rolling balls, past middle of dungeon, same as Substancia.

Shooting Aur: Substancia
(this is actually Dimentora, somehow they gave him 2 different names)
Physical Attack: 2045 - 6135
Magic Attack: 3067 - 9202
HP: 3.321.735
Only spawns on "HIGH" boss spawn. Again, a heck of a lot of HP, but is no different than Dimensic version, just near 50% more hp, slighly stronger attacks, no big deal.
Just to remind, short range physical AoE.

Vipenalt: Substancia
Physical Attack: 2018 - 6053
Magic Attack: 3026 - 9079
HP: 1.944.137
Only spawns on "HIGH" boss spawn. Again, will only attack with Wood element attacks, and past 50% HP the "clapping hands" will show up (DONT MOVE!), but besides that, his magic attack got a lot harder (double the damage than before) and might kill your tanker faster than you can heal. Either get better gear/tanker or use a secondary cleric to blue bubble the whole fight. But mostly he wont be a problem.
