I prepared a list of questions out for right support and help from the veteran players. Also I have gone through available manual and Gamefaqs or other online guides too, so please excuse my lack of knowledge in regards any question repeated or found silly as I am new to gothic 2 and even the series.

1. In QUEST: The False Messenger - Kardif mentions to meet a merchant If I want to buy the Map. Which merchant should I exactly meet? I even strike up a conversation with Attile but no option of any map to buy.

2. Under Controls Menu, I can't locate "Spell Casting" keys to bind or change. Are they default to follow? (Key "4") Is there any way to change them? I am playing with Gothic 2 Controls.

3. Is it possible to drop a single item of Gold or objects from (own) Inventory? (say drop 1 coin out of 12 Coins of Gold)
I can equip objects from other NPC's inventory or chests either totally or single but can't drop them Single one-by-one from my own inventory.

4. I have become a member of thieves guild and completed all the quests. Can I still expect Paladins to join the guild?
Also, are thieves guild separate (independent), in the sense, Can I still play Thieves Quests even as a mercenary or mage (except Paladin)??

5. I have too many items in inventory and want to find a suitable chest or even a private room to dust out unnecessary load and save them. Currently at Dead Harpy saved my inventory items for 50 gold coins weekly rent. Do the items disappear from the chest (at Dead Harpy) even after long sessions of game or changing chapters?
Is it possible to transfer inventory items with any accessible chest(s) throughout Gothic 2 and expect them to stay even after changing Chapters?

6. In the Quest The Experiment by Ignaz to test Oblivion spell, I knocked down Valentino and immediately cast the spell Oblivion. The quest was successful but when I strike conversation with Valentino he still says "Leave me Alone". If the spell was successful than why doesn't he repeat the lines when I first met him, namely, ladies man and all that.

7. In the Quest Canthar's Favor to frame Sarah, I actually went to Lord Andre and collected the bounty to arrest Canthar.
According to an online guide it is possible to visit Canthar in jail and kill him either wielding sword directly or run by making him to follow and let the guard do the killing. This trick works in the quest "The False Messenger" where Moe follows me and after getting hit from Moe, nearby guards knock him out.
But it is not working under Canthar's case, I hit Canthar and run all around Lord Andre and the guards but, in turn, they encourage Canthar saying lines, namely, "Get him for good" and moment I wield the sword entire Khorinis goes crazy to knock me out. Why don't the guards react to Canthar's act (even he runs out of jail to follow me)? I just don't get this

Well that's the list (for now) of doubts and request some pointers of help

The map seller is Brahim. He isn't one of the regular merchants. You'll find him near the tavern. Refer to this map. The rest of the Gothic 2 Database is also very useful. Magic is bound to 4-0 in whatever order you assigned them, so to rearrange them you must deselect and reselect them to get the order you want. 3 equips whatever the last used magic was. I'm not sure if you can drop stacked items selectively, but you should be able to move them into chests selectively. The thieves guild don't care what faction you're in. All chests, dropped items, etc. are persistent and never reset or disappear. Corpses do disappear so of course you'll want to loot them before this happens. This is normal. From memory you need to wait a day or so for him to go back to normal. Once that amount of time has passed you can talk to him in the tavern. You should be able to get this to work using a bow or magic. Stand in the far corner of the outer room and you should be able to just see him through the cell door. Target him and hit him once. He should then start fighting with the guard. Save before you do this because sometimes Canthar will win the duel.

After the guard beats him up he'll return to his cell. Get in there ahead of him and stand in a corner where you can't see the guard's usual spot (otherwise he occasionally notices the murder). Knock Canthar down as soon as he stops moving and finish him off otherwise he'll start healing himself by eating apples and such. You'll finish the killing animation in full view of the guard but initiating it from an unseen location seems to be enough for it to go unnoticed.

Oh, and don't try looting Canthar's corpse. The guard doesn't mind murder, but theft is unacceptable. ;)

Thanks a ton Arkose. The Trick to Canthar was very helpful too :)

So that's how it works. I shot him/cast the spell from the far corner of the cell where I was unseen then ran for my life and the guard just sat there. Wondering why that never worked for me.

Title seems fitting enough and I do not want to make a new thread.

What is the switch combination in Chapter 6 for the both rooms UP on either side? I have tried :
L,M,R
L,R,M
M,R,L
M,L,R
R,M,L
R,L,M

all failures... one side spawns annoying smoke, the other side always two Skeleton Lords... A guide sais the combo is M,L,R.. I have tested this extensively enough to call bulls. on that walkthrough. Anyone help me here?

Not sure what the abbreviations mean but I think I know of where you mean. Unfortunately, I don't know. I have a terrible memory so I just keep trying things until something works. If we are thinking the same place, that smoke is more then annoying as it causes health damage.

it means L = Left R= Right M= Middle as the upper staircases have 3x Switches and I tried ALL combinations that would allow only one switch to be pressed... If i am allowed to push one more than once... well, then we have 3^3 combinations. which is 27 afaik.

Yes we are thinking of the same place... glitched myself threw the doors by morphing in to some monster, standing next to the door and morphing back (this spawns you on the other side). I think my game was just bugged (not triggering the middle (floor) switch for some reason and only triggering the bad stuff. Oh well. If anyone can remember the correct combination, please let me know. Also how to open that final Black Dragon eye gate... thanks.

I have some thoughts to share and may help you. Actually there is a potion called Embarla Firgasto requiring some 10 Dragon eggs. I have searched some online forums and even at gamefaqs where they mention that the gate or the room won't open unless you equip this potion or have drank it. I can't confirm this since currently playing through Chapter 4 but soon will inform whether this is true or just a minor glitch. Just try it if you have previous saves where the potion receipe is available from Neoras.
