This is surprising => the locked hatch is supposed to stay locked until you got Sigurd's quest to kill Groblar and get the key by killing his bodyguards (was already locked in 1.1 or 1.2?) => before that, this quest was really buggy.
Before going into town and visiting the Keeper of the Ranks I already had 7 quest items in my inventory. (Mirror, Raanaar Urn, Bat Guano, Old Cheese, Holy Relic, Spider Web, Demon's Bane Gem). After talking to him I tried to complete the Holy Relic Quest but the guy will not acknowlege that I have it
Mirror, urn, bane gem => no ranking quests => Raanaar rebels
Guano/cheese => did you talk to the Talking Tibar in the outskirts? He has a ranking quest for you.
Relic => have you looked at the billboard and got the info that a certain monk needs help? Did you go to him then and collect the quest?
Spider's web => were did you find this? I can't recall a quest for it. Is it from Act 2 maybe?
The Raanaar rebel quests are sub quests. MAIN plot is this => become Nr 2 due to ranking quests - then challenge Nr 1 (or she challenges you) - kill her => entry to Black Bishop => get the quest to retireve the Staff of power => enter catacombs. Fight yourself through, solve the tests there.
How high are you in ranking? I need the ranking XP. please.
