I would like clarification on some points, if possible with rule sources, regarding Magic Dead Zones (and, maybe, Anti-Magic Fields):

• Do potions work at all? In an MDZ, there is no conduit for magical Energy. It's clear to me that a potion is used up, but what about the (clearly magical) effect? as I do it now: potions work.
• It is clear to me that if the weave is not existent, wands/dorjes¹ won't work. Do they still lose charges? I am tempted to have these things ignore/"miss" their triggers altogether
• In an AMF, incorporeal undead cannot exist (winking out). Does that work the same way in MDZ? I am doing the same as for AMF: Incorporeal undead do not work
• What about corporeal undead, animated by magic? These "work" (read: continue to be animated) inside AMF; what about MDZ? I also let corporeal undead work along with any (Ex) they might have

¹psionics-is-magic rule is in effect in my games.

I do have my own adjudications of the matter, but I am asking for rules backup (possibly with sources).

As for the system question: I am using 3.5 and Pathfinder (a mix) with PF taking precedence wherever it contradicts 3.5 rules. Both rulings would be of interest though. The setting I run is Forgotten Realms.

Edit: clarified title.
