The Rose Cross is another
more advanced form of
blessing an area for ritual
as well as making oneself
psychically invisible so that
others are not aware of their
presence.  This is not to be
used for any malicious intent
but merely to avoid conflict
with those present (humans
or spirits) who would be
disturbed by the magical
operation the magician is
wishing to "cloak".  Used in
conjunction with the LBRP
and the BRH, the Rose Cross
can be a very potent and
effective banishing ritual.
