I would like to include a dead magic area in the adventure I am running that takes place in Faerûn. I have a couple of questions I would like to have clarified.
Most of your questions seem to be answered under the "Effects of Dead Magic" on page 56 of the FRCS.
What happens to spells, for instance a fireball, that is cast outside a dead magic area and passes into a dead magic area? Does it dissipate right as it crosses the boundary of the dead magic area?
For the most part, a dead magic zone is like an
antimagic field. A
fireball that has its center designated at any point within the dead magic zone will simply not go off. Likewise, if the
fireball had its point of explosion set outside of the antimagic zone, any part of the radius of flames that would be in the dead magic zone simply don't appear.
Can creatures of the magical beast exist in dead magic areas? How about golems (as they are created with magic)?
Yes to both.
Antimagic field's fourth paragraph talks about this.
Do psionics work in dead magic areas?
This is covered in
Player's Guide to Faerun, page 172, second paragraph under the "Psionics and the Weave" header:
While psionics does not require the Weave to function, psionic powers are magical in nature. Spells such as detect magic can also detect psionic abilities at work, and spells such as dispell magic or antimagic shell can negate, suppress, or completely cancel psionic manifestations. In Faerun, psionics and magic are not transparent to each other; they interact exactly as magic interacts with other magic
Any other important points I should consider before introducing a dead magic area into my game?
A few specific things to remember about dead magic zones:
A spellcaster or creature with spell-like or supernatural abilities (Shadow Weave user notwithstanding) immediately knows when it enters (and probably exits) a dead magic zone. They can take a move action to note the exact boundary of it.
When outside one, a Weave user (as defined above) can use
detect magic to "delineate the extent" of a dead magic zone.
Divinations can't detect subjects within such a zone.
You can't teleport into or out of a dead magic zone.
A
wish or
miracle permanently repairs all dead magic zones within a 30 ft. radius of the caster (or that much of a larger zone).
Unlike an
antimagic field, a dead magic zone doesn't stop the spells, spell-like abilities, and supernatural abilities of a being with the Shadow Weave Magic feat (nor would it stop the psionic powers, psi-like abilities, and supernatural abilities of a psionic creature with the
Conjunctive Mind feat), because dead magic zones are Weave-specific. There could be Shadow Weave dead (or wild) magic zones, which wouldn't affect Weave users, but so far no such things exist.
