For this quest, I need to collect Deformed Gems from 5 different Bosses in Abyss Mode.Here is the problem:
I cannot find one of the Bosses. The quest says I need to go to Mountain Corner -> Dark Overlord Crossing -> Dark Territory Guard Force Base
to collect the Marcus Tacitus' Deformed Gem. But there is NOT such a place... Dark Manor, Training Grounds, Dark Tower... But not Dark Territory Guard Force Base. I thought about a translation error, so I did all the instances there in Abyss Mode, but no luck. Even in chinese the name doesn't match with any instance. Anyone knows where Dark territory guard force base and/or the Boss Marcus Tacitus are?
