- A God Am I: Seems to believe that her experiments will lead her to godhood.
- Bait-and-Switch Boss: When fought in combat, you'll find out that all she can do is to throw explosives at you and slap you, and she'll probably die faster than her bodyguards.

- Blob Monster: Turns into one (or rather, sprouts from her corpse) upon death.
- Cloud Cuckoo Lander: A rather creepy variant.
- Death Seeker: When you meet her the second time, she actually wants to be killed by your hands, so she'll be able to reach the last step of the evolution by turning into a black, horrible slime monster.

- Evil Redhead: With hair shaped like flames to boot.

- Lady in Red: She's dressed most entirely in red.
- Large Ham: Especially before showing off her true form.
- The Man Behind the Man: To the Red Fangs.

- Death from Above: Getting hit by his spellbook (which homes on the target) will result into a couple of ice meteors falling on the ground, freezing and damaging everything around.
- Evil Sorcerer: Implied by the journal of a dead guy in his crypt, stating that he's desperate because Lyran has locked him inside the fortress and now is coming for him. Plus there's the whole implications with his weather-controlling machine...
- Faux Affably Evil: Compliments you for finding his private study, right before threatening you and coming after you with murderous intent.
- Hoist by His Own Petard: Some of his spells hit a whole area and can break pots, so it's possible for him to accidentally smash his own Soul Jars.
- Puzzle Boss: Later in his crypt. He's the only boss of the game who needs a peculiar strategy to be vanquished.
- The Undead
An illithid residing in the depths of Dragonspear Castle. She has gotten her hands on the Brazier of Eternal Flame.

- Flunky Boss: The flunkies are her mind-controlled Zhentarim. Which can still be controlled by Ysuran nevertheless.
- Giant Space Flea From No Where: Yes, you're warned about the "unspeakable horrors from the Underdark", and yes, you come across some driders and ropers but: did you really expected a mind flayer?
- Glass Cannon: Not very though, but her mind blast attack (especially the fan-shaped one) can be deadly if shot point-blank.
- Mind Control: She did this to her Zhentarim pets, but it doesn't work on the hero. In battle, her mind attacks are represented as a weird-colored spray which stuns and damages the player (and, if close enough, can be fatal).
- Oh, Crap: When she realizes that her mind trick isn't working at all.
- Vocal Dissonance: She looks identical to the mind flayer portrayed on the Monster Manual (3.5), but her voice is clearly feminine, and not even ugly at that.

- Evil Sorcerer: Mostly attacks by casting spells and is implied to have turned the pirates and Captain Khoris into shambling undead.

- Sinister Minister: The High Priest of the Kuo Toa deity.
A sorceress working for the Zhentarim. She's killed in the Elemental Plane of Water.

- Bald of Evil.

- Exact Words: He swore to protect the Air Foundation with his life. This comes back to chomp him in the butt later.

- We Can Rule Together: Congratulates the player character and offers him to embrace him and take him under his wing as his ally before they fight.
