ok, but in the case that it is not counted as a form of stun, you also reduce it after the rounds of SNP and stun? Or ignore MP?
RM classic book says:
Effects of Must Parry: Being knocked off
balance or out of position, either physically,
or mentally, results in the target being
unable to execute an attack. They can parry
with half their OB, or perform a movement/
maneuver at -25.
Note: “Must Parry” results are not
stun rounds.
OPTION 14: “MUST PARRY” AS STUN
Some GMs may wish to treat “Must
Parry” results as stun rounds. If so, treat
them as a weaker form of stun than “Stun”
so that they take effect and wear off last.
(Be aware that using this option makes
creatures immune to stun more powerful.)
