You appear to be describing Divine Protection. We do not need
anymore additions to pacifism or protection or other such
means of opting out of combat. The protection already
available does have spin-offs for others, as mentioned
by Proteus earlier. Unfortunately I wont be here for
what promises to be a very interesting debate, but I'll
be eager to hear the comments passed and any conclusions
carried when I return.
