Every time I go to the githyanki, no matter what choices I make, they kill Laezel before she manages to do anything much, I can restart the battle many times, and most times she's dead long before anyone gets to do anything ... it takes several restarts just to have her still alive after the initial initiative round ... so I don't know what you're doing to make them very killable, but it's not giving me that option ... the only way I can imagine getting it done is to go back to camp, and keep bringing back all those barrels of smokepowder and oil, and setting a massive trap for them, but which will sacrifice laezel at first until resurrection, but the problem with that is that it doesn't seem realistic to do so, and I would need to turn up without her at first and get it all set up in stealth mode ... otherwise it's just more of the same with everyone dying after a fairly short battle
