Well, I'd rule (or at least, house rule) that immunity only blocks detrimental effects. Whatever is considered "detrimental" would be up to the character/creature with the immunity at any given time.hong said:
Including bless and aid? How ridiculous.
Perhaps the intention is that the paladin is immune to such effects but can switch it off _as if_ it were SR. Not that there would be any reason to do so in the paladin's case, but for the HL it's useful.
