The 3 Drairs in Baldur's Gate must be killed. After killing them, you can get 2d6 great swords. The functions used are also quite good. Players can use them according to their own needs.
Answer: Must kill
When the player encounters Gendrell, he is hunting Asdalen and bringing him back to Baldur's Gate.
Then have a conversation with Lai. During the conversation, you have to choose to kill him and then kill him.
After the kill is completed, you can obtain the previous 2d6 sword, and at the same time, you will advance the plot and enter the next level.
Then go back and continue the conversation. You can choose to be silent during the conversation so that the battle will not be triggered.
