Dude... Why didn't you leave IMMEDIATELY before doing the quest...
Yeah, I might have not predicted what the elf would do... but that was because I expected them to make the quest into the trap and kill mc's party. So doing the quest would've been a death-trap.
In a way he was lucky, with how they only targeted the others. Since this means he survived.
Now I am just curious if he thinks he can kill that elf guild master, or if he just flees. With the girl's abilities (creating specialized gear) they could have done the former easily, but it would be difficult with only his own abilities&gear. But he might still manage, particularly if he manages to touch the elf inconspicuously (impossible to do) and analyze him + edit everything to trash.
