no vampires so %b and %B are pointless (can & should be removed from helps)
%S is non functional, it's intent is to display what style you are in. (should be fixed) probably just by moving the style func's display over to it in the prompt substitution.

have not checked ALL %tags but those are the probs I've seen sofar.
&w[&R%h&w/&r%H &B%m&w/&b%M &C%v&w/&c%V&w] [&O%S &w(&W%A&w)]

long but a good prompt :D

Also note that the %A invis/hide/stealth indicator should probably show a none when no effects are active.

%s works just shows the first letter only.. my bad.. thought it was striping the % and not displaying cause I was in standard style
