YMMV / Perfect World

• Anti-Climax Boss: There's a certain level 100 boss you're expected to fight solo when you're level 30. Don't be afraid: he dies quickly and, in fact, doesn't attack at all. The only danger is his tendency to flee into a crowd of aggressive mobs...
  • To clarify on this, the boss is also completely immune to magic in all forms, which scares ignorant newbie spellcasters. Fortunately, this boss actually dies in a few punches even from the weakest spellcaster. As mentioned above, he DOES live near a dungeon entrance full of elite mobs 50-60 levels higher than the average monster in the area...
• Awesome Music: The Archosaur theme. It's the choir that does it.
  • Some of the music from the Genesis expansion. Gorgeous. Really captures the mood of the area.
• Best Boss Ever: A melee-oriented boss who's the only foe of his kind ballsy enough to try and kill players with Chi overload, which those with the right Transcendent skills can easily use to their advantage via debuffing attacks? No wonder Blademasters and Duskblades, and to a slightly lesser degree Assassins (who either have high enough Evasion to avoid being hit, or can time their use of invulnerability potions just right to safely ride out his "berserk" state) find Tyrant Prince Mushi a veritable joy to fight.
• Difficulty Spike: Players entering Flowsilver Palace for the first time will find a sudden, sharp upswing in the number of boss attacks and other things that can One-Hit Kill them if they are not careful.
• Goddamned Boss: For Wizards and Psychics, the aforementioned level 100 enemy Kun Kun is this. While most classes have no problem killing him (meleers have little problems, for obvious reasons; Venomancers can simply sic their pets on him; Clerics can use Plume Shot and fly out of the way of the stronger enemies), Kun Kun is 100% resistant to spells. This means that the unlucky Wizard or Psychic must now physically smack Kun Kun, doing about 3 to 4 damage per hit. And since he runs so much... Of course, Wizards can just patiently wait until they get their level 59 skills and oneshot the damn thing with a rain of flaming blades ^note aka the strongest attack in the entire game since it uses the wizard's already insane magic attack twice; the highest known damage achieved was over 13 million - with strongest gear in game, a critical hit and a ton of debuffs on the target. 1 million is achievable relatively easily with semi-endgame gear and some debuffs. The game has gotten a lot more options to further enhance the players' stats since then, and higher damage should definitely be possible. On the other hand, Psychics are totally screwed, especially since their weapon has lower basic physical attack than the tools Wizards usually use.
  • Any one of the three "gatekeeper" Wraith emperors that stand in the way of the player party's fight with Aurogon the Dragon Emperor in the Advanced Endless Universe (Aohe the Dark Emperor, Chigo the Serpent Emperor, and Locen, the Emperor of Flame) may elicit frustrated groans from the entire squad depending on its class composition and overall power level. To wit:
    • Aohe's path is almost always the easiest, as it has a single target that must be destroyed before the Dark Emperor splits off into Aohe Snake (physical-immune for casters to attack) and Aohe Dragon (elemental-immune for meleers and Archers to attack). If the party has a Psychic with the Soulburn skill or a Cleric with the Magical Shackle skill, this player can one-shot the target (the supposedly damage-immune Aohe's Spirit) and shorten the fight by a considerable margin. If not, then the squad must follow a much longer route to make Aohe killable. Then when the party is split off to fight Aohe Snake and Aohe Dragon, these two targets must die within ten seconds of each other, or both will revive to full power and the party must start this phase over. Any squad that is over-balanced on either end in terms of physical vs. magical damage-dealers is likely to have coordination difficulties.
    • Chigo's path is probably the most tedious. Your NPC ally, Luminous Jade, will split himself into Light Jade and Dark Jade, each of whom will stand at one end of the dungeon and absorb "Destructive Force" generated when the player party kills mobs that swarm around two glowing pearls in order to make Chigo able to be killed. Each half of the squad must kill its mobs at the same rate (i.e. difference in the amount of Destructive Force each Jade absorbs cannot exceed 4 units), or the total Destructive Force will rapidly drain. This is impossible to perfectly coordinate between two halves of a player squad.
    • Locen's path, however, is the most complicated, usually leading to the most screw-ups that make it take longer. As soon as eight players unseal Steel-Eyed Shakti from her magical prison, you've got to head to the scent-masking skyclover bushes in one hell of a hurry because that's when Locen will start stomping all over the place in search of unsuspecting players, and not only is he invulnerable until the very end of a long puzzle, but he hits like a semi truck and moves even faster than a Barbarian in tiger form. Ready for that puzzle? First you've got to collect the Thorny Cocklebur Seeds that Steel-Eyed Shakti needs to make her Pill of Endless Sight, used to see a quartet of otherwise-invisible Scouts you must kill later on. Then to make the pills, one player must operate the Alchemy Furnace (blowing air and adding water at Shakti's cues) while three others must attack three "flame" mobs, neither killing them nor letting them recover to full HP, and still three more players must kill the minions that will try to attack the furnace operator and fire controllers. Not only are you on a time frame (need to create pill before Locen makes his rounds and curb-stomps any players he catches outside the nearby bushes), but if the party makes ANY mistakes (killing a fire, allowing a fire to gain full HP, performing the wrong action at Shakti's cue), the entire furnace quest will fail and must be started over. After making the pills and killing the Scouts whose presence can now be seen, one player must disguise him/herself as a minion to speak to either the Alabaster or Obsidian Transient in order to gain the Brilliant Inscription necessary for setting a trap that will enable Shakti to destroy Locen's invulnerability enchantment. If a Scout is left alive to squeal, if a non-disguised player allows the Transients to see him/her, or if more than one player tries to speak to the Transients...they'll start attacking and must be killed before the Inscription can be taken. Once a player has the Inscription and uses it to repair the Nine-Point Sealing Matrix that must then be activated to set the trap, the others must kill the physical-immune Firethorn Snakes and the elemental-immune Manshu White Beasts to acquire Devil Snake Bones, as these are used to activate the correct points on the trap matrix. Activate any wrong point, and - you guessed it! - the matrix resets and the correct points must be re-activated. Only when Locen is caught in the trap, and retreats to the central island to recover, can he be hunted down and killed.
  • Belle Leun, the Mad Princess, the boss exclusive to Flowsilver Palace's Judgment Mode, is infamous for summoning waves of Ghostchill Heralds and Ghostchill Sorcerors that are nigh-immune to certain damage types (elemental for Heralds, physical for Sorcerors) and continuously fire off area-of-effect attacks that slow, debuff, and inflict damage over time on the entire squad - at a fast enough rate to make any effort to remove the debuffs pointless. As each wave of these minions is triggered when the squad has brought the Mad Princess's health down to a set point, damaging her too fast can easily mean the squad gets in WAY over its collective head. After seven Ghostchill waves, when Belle Leun is down to a third of her health, she will summon an intervening mini-boss, becoming invulnerable until her chosen interceder is defeated. Through the rest of the fight, she will repeatedly cast a Dark Curtain that increases the cooldown of any skill used to 2 minutes while it is in effect (essentially rendering all the spellcasters unable to attack), and also cast a Dark Link on a random player that heals her if the linked target attacks. Periodically a Ghostchill Demon will spawn in the room as well, reeling in and then one-shotting every player who doesn't either run behind Belle Leun's platform to avoid it, or use an invulnerability potion.
  • Night Templar Kivon, fifteenth boss in the Icebound Underworld, makes himself even tougher and more annoying than most of his brethren by stealing players' Chi so that they can't use their most powerful attacks to shorten the fight. If any player succeeds in inflicting a debuff on him, he'll just transfer the debuff to another (random) player. This tactic on his part is particularly bad if someone tries to use a Damage-Increasing Debuff such as Amplify Damage, Blood Vow, or especially Heaven's Flame.
• Purgatory and Limbo: If Lothranis and Momaganon are the denizens' idea of Heaven and Hell, respectively, then the Seat of Torment (instanced dungeon within Lothranis; consists of high cliffs amid perpetual rainfall and many monsters with a name prefix of "Infernal") and Abaddon (instanced dungeon within Momaganon; is an idyllic spring valley once players pass the gauntlet of burning boulders near the entrance, and many monsters with a name prefix of "Peachyard" to go with the cheery theme of the scenery) would represent these themes.
