In my playthrough Bulette didn't even burrow out until I reached the Sussur tree loaction.
I'm also not sure why people are even attempting a lv5 boss without having a source of Bless in the party to actually land skills on a mob 1 level over you.
In that party comp 2 out of 4 didn't even have Darkvision.
I'm not really doing normal playthroughs at this point, I'm breaking things, looking for bugs. That being said, with only 40 damage left to do and 2 wizards with magic missile, one wearing sapphire spark, one invisible out of combat, had I cared and not quit after taking that screenshot, it wouldn't have been a problem.
