.. did you know that a Nephandus takes damage when the opposing vampire plays Catatonic Fear even though damage against strikes or damaging effect made against him inflicts 1 less damage? The reason that Catatonic Fear deals damage against a Nephandus is that the damage of Catatonic Fear us delivered after combat whereas the damage reduction effect of the Nephandus is only applied to damage dealt in combat.
REVERSAL: I think, I read LSJ's answer in the above reference not correctly in the first place. He's arguing that the strike was done in combat and the Nephandus' special effect is therefore applied. Thus the Nephandus does not take damage at all by the Catatonic Fear.
