Hello fellow rule lawyers!
Brother Corbulo's ability "The Red Grail" states that friendly Blood Angels Infantry and Biker units get +1S while within 6" of
any Sanguinary Priests.
The Sanguinary Priests themselves have
another rule, named "Blood Chalice", that says the same.
Since the rules are not the same (different names, and The Red Grail has some more stuff), are they cumulative?
If yes, are multiple instances of Blood Chalice (running several Priests) also cumulative?
Pretty sure
RAI is not cumulative at all, but
RAW suggest otherwise.
