They can be used to bypass surfaces obstacles or to sneak away from enemy's by teleporting all your group to one location. You can do many things with it...
It's technically always was a bug as it could mean lock picking doors and portals are useless in the game. Portals meant to be open with the amulets and locked doors or locked areas and walls cannot be used with the pyramids.
Edit: If they are interdimensional they only should limit to portals or locked doors or magical locks, because lock picking and amulets will be kind of useless than.
I was only joking with the inter-dimensional schtick.
I guess i just got used to the wrong way too much. I forgot they were meant to have a less gamebreaking purposes. Actually, i dont even use them when im playing, because it seemed so cheap to throw them through doors and various gates. Not to mention kiting enemies with them.
Will be refreshing to play with them properly.
Bug:
Im noticing my dead characters are regenerating health - all on their own.
Maybe a bug:
There is too many rings with completely same stats popping up - mostly a ring that gives loremaster +1 and telekinesis +1.
I think i got at least a six of those.
And several that are magical but just unbreakable.
There is much less magic rings to be found, which is good but... would be nice if they were more diverse.
Not special and super awesome. Just less clones of that one would be good.
Helmets and bracers with stats could be bit more diverse too.
Boots seem ok more or less.
