Only solution is to create new character and dont do Quest bug, because her bugged q drop is practialy used instead of Terror drop. You will get her normal Quest drop instead.

Why? Because if you do that and she is terrorized, you wont get that sweet super high Treacure class loot with possible elite items. This actualy resulted in kind of hilarious situation, because now you actualy dont want to quest bug Andariel.

Treasure class increase so they could drop more elite items and level increase so they have actualy higher level to even drop them as uniques and sets do require certain item level or so called q lvl to drop. Blizzard introduced two things improving loot from bosses based on their levels. From point of player playing pre 2.5 was everything fine. They avoided dealing with a bug by Andariel going to Quest drop line even when you didnt kill her on quest or if you killed her without q bug. I dont know what exactly is said in patch notes but if they by any chance said that bug was fixed, its not true. Ok thats for the History lesson and now we are back from ancient times to 2022. You basicly had to create new character to have her quest bugged with right process again. If you left game in ACT I after killing her, it resulted in not having Quest drop bug.

Not dropping Junk (keys, arrows, potions, gold…).

Meaning that she was dropping Quest drop every single game with: For those who dont know what used to be Andariel Q bug, it was situation where If you talked to people in town and progressed to ACT 2 in same game where you for the first time ever killed Andariel on quest, you had her quest bugged forever.
