Q25: Is there any way to allow a Lawful Incarnate to take an Evil meld?
A25I guess if you can somehow get ahold of the evil subtype (Savage Species ritualts, horizon walker, maybe some other PrCs...). Alternatively, make a pact with a devil (I believe you don't have to qualify for bonus feats gained that way; so just take shape souldmeld: evil meld).
...Ninja'd.
Q26Which undead can both be created via spell (so that corpsecrafter etc apply to it) and are playable (i.e. have a listed LA)? I've been going through
this list and only found the Curst (UE). They're LA +3, though, and have abysmal stats.
EditInfinity: I just found the
update for 3.0 FR Monsters; and found others that qualify:
LA+2: Cryptspawn (MoF)
[LA+4: Zin-Carla (F&P)] not a spell, but a (Su) ... hmm
LA+6: Spectral Mage (MoF)
LA+8: Silveraith (City of the Spider Queen)
Necropolitan and other ritual-based thingies don't count. Bone/Corpse Creatures would be perfect (one again...), but they're unplayable as is.
