Shoot, why didn't I think of that?

The problem wih just not having them is that the concept I'm thinking of
is one where always- items are very apppropriate, if rare (eg, Macbeth,
who could not be slain by any man born of woman -- so he got knocked off
by a guy ripped forth from his mother's womb who was not technically
"born"). On the fourth hand, it might be best just to handle these few
items as special cases; it's entirely possible for  mountains to tremble
and the seas to boil when the Invincible Warrior Karnak battles Dargba the
always-victiorious.

Hmm, I guess. I can see for cases where you transform a slug into a dog,
it would be easiest just to spoof it.  (Well, actually, I'd swap the
slug's mind into another body and put the old body into storage, but there
you are).  On the other hand, for stuff like the elven forest scenario, I
would personally give everything in castle krak a permanent affect that
alters their "draw magic" or "use magic" skills.  The sort of affects I'm
visualizing can have functions attached to determine their effects, so
it's no problem to give them something like "if the scepter is in the
forest, set draw_magic skill to -999, else don't change it". I dunno. This
way seems more sensible to me .. but perhaps I'm not clear on how you plan
to actually implement the spoofs?

It's pretty obvious there's months and months of serious debate on this
stuff that I've missed. I have the vague idea this list is archived .. how
can I get at the archives?
