In Mae-Var guild house on the last floor where Edwin stays - there is a door behind him (up-left) what is locked. do you know how to unlock it ?
I asked this before, but things may have changed - in the Planar sphere where it is the cowled wizard (or may be in the room where is the necromancer) again up-left there is a door what I can not unlock. Can it be opened ?

many of these doors are just there for look, not usable.

IIRC the door in Mae'Var's guild cannot be opened. It's a fake door - quite typical for thieves, isn't it?
I am not sure about the other door you mentioned, as I do not remember it. The necromancer I assume is Lavok (Valygar's forefather and owner of the sphere), but the only door up left I know leads to a room with

a group of lizard men and should not be a problem.

Aha...ok.

No, no the door what leads to the lizard men. There is a door what says 'locked' and because the previous answers for it were like the Tyrion's one it seems that it is another fake door.

Wat I would do is cheeting!
just get a "knock" wisard spell scroll and learn it! this spell will just open all locks!!! Good luck!

...or can't be opened by magical means...

The BG1 problem of unpickable locks seems to have disappeared in BG2. I haven't met a non-magical lock in BG2 that couldn't be forced, Knocked, or picked with a Master Thievery/Perception potion. There is a way to open everything, and some are puzzles. [img]smile.gif[/img]
