Picked the least suitable units to fight the crusaders at the coalition camp.

Chapter 10, Coalition Camp When the Coalition Camp is under attack, Caelar's forces will attack in four waves. You have to choose from your own units who should fight during the first three waves. For this achievement you'll need to pick the least suitable ones. There are more variations for the achievement, but this one worked for me:

• First wave with trolls: pick the rogues
  
• Second wave with mages: pick the archers
  
• Third wave with troops: pick the wizard slayers

Once you defeat the leader of the fourth wave, the orog Grimgor, the achievement will unlock.



Defeat the elite crusader Ashatiel in a one on one battle.

Chapter 11, Dragonspear Castle Exterior Once you encounter the celestial Ashatiel, simply challenge and kill her. Don't let your party members interfere or else the achievement won't trigger.

Thrix claimed a party member's soul.

Chapter 12, Avernus Bridge Answer Thrix's riddle wrong while bargaining a companion's soul and the achievement should unlock once the dialogue is over.
Bugged! Workaround: After Thrix ended the dialogue and vanishes, immediately press pause (but before your companion starts complaining). It should trigger the achievement. If not, try to quicksave while the game is still paused.
There's also an unofficial fix made by badungu here[forums.beamdog.com] or use the ingame console:

Chapter 13, Baldur's Gate Incriminate yourself during your trial (meaning: the exact opposite of the list above) or simply don't defend yourself at all. Escape the prison then through the sewers where you encounter Duncan Bence and Corwin. When confronted by Corwin, surrender to her, she will then believe you and turn on Bence and unlock the achievement for you.

Kill the lich and quickly find his phylactery (the lich will respawn after a short time). Throw it into the portal to the Fire Plane (south-west of the map) to destroy the lich once and for all.

Chapter 10, Coalition Camp During the quest "Troop Train" talk to the recruits Garrold, Taield, Danine, Clovista, Morlis and Hester and train them to impress Vigilant Hasalan.

• Taield: Jaheira
  
• Danine: Safana
  
• Clovista: M'Khiin or Glint

Present evidence of the crusader's crimes to Julann.

Chapter 10, Underground River Entrance
Note: Julann and Rigah will only talk to you if you have Minsc and Dynaheir in the party!

Sided with the surface druids at the underground river entrance.

Perform a task worthy of the Terrible Trivium.

Chapter 10, Underground River Speak to Ladle and ask for work. He wants you to move a lot of heavy sacks to another crate. Do so and speak to him again. Now move all the sacks back to the original crate. The Terrible Trivium would be proud of you.


I suggest you combine Dorn with some boots of speed or a haste spell to speed things up - you have a war to win after all.



Reunited the spirits of Daeros Dragonspear and Halatathlaer.

Chapter 10, Underground River Speak to the ghost of the dragon Halatathlaer and free it from the necromancers in Kanaglym, then go to the Dragonspear Castle basement and speak to Daeros Dragonspear's ghost in Hephernaan's chambers.

Chapter 10, Dragonspear Castle Basement Once you've entered the basement, go to Hephernaan's chambers and pay him a visit. When he's near death, he will teleport away and the achievement will unlock.
Note: If you enter the basement and get back to the Coalition Camp before talking to Hephernaan, a messenger will inform you that Caelar wants a parlay. If you then go back into the basement, Hephernaan will be gone and you've missed the achievement.

And at last the time-consuming achievements, which takes more than one chapter to unlock. Sorry, couldn't think of a proper title for this section.

Recruit all the bonus allies possible for the final battle.

  When you encounter the mage Teleria in the forest clearing during the quest "The Vanished", ask her to sell the golem to you.
  
• Slug and Murs (the ogres) [Chapter 10, Underground River Entrance]
  Once you encounter the ogres, fight as Murs' champion and then agree to find her mate Slug. He can be found and freed in the Dragonspear Warrens (access through the Underground River). Return to Murs and ask them to fight beside you.

Possibly bugged! You won't get the achievement, if you use the barrel of Bwoosh and get through the main entrance. Instead enter Dragonspear Castle through the weak wall at the side.



Fight all the bonus enemies possible at the final battle.

In Chapter 11, during your assault on Dragonspear Castle, it is possible for you to encounter various enemies depending on your prior choices. You need all of them for this achievement to unlock.

  Make sure they leave for Dragonspear Castle.
  
• Strunk [Chapter 10, Underground River]

Answered the menhir's riddle, Vidyadhar's riddle and Thrix's riddle correctly.

• Menhir [Chapter 8, Coast Way Crossing]
  When doing the "Ancient Menhirs" quest, sing to the one next to the stone statues with a low charisma character. It will then ask you a riddle and the correct answer is "The wind blowing in a tree next to a river."
  
• Vidyadhar [Chapter 10, Underground River]
  You can locate Vidyadhar in the same room as the two sahuagin, though you have to pull it with the Spectacles of Spectacle to the Prime Material Plane first. The correct answer for the rakshasa's riddle is "Bees"
  
• Thrix [Chapter 12, Avernus Bridge]
  Once you encounter the devil Thrix, bargain the soul of one of your companions and answer his riddle correctly with "Murder"
