Quote:

Great Despair (aura, divine, emotion, enchantment, fear, incapacitation, mental) 30 feet. Living creatures are frightened 1 while in a mummy guardian’s despair aura. They can’t naturally recover from this fear while in the area but recover instantly once they leave the area. When a creature first enters the area, it must succeed at a DC 26 Will save (after taking the penalty from being frightened) or be paralyzed for 1d4 rounds. The creature is then temporarily immune for 24 hours.

My inquiry has three parts here. First, does the 24 hour immunity apply only to the paralyze, or to the entire aura?

Second, if the immunity applies only to the paralyze, is there any save to the fear or is that just a gimmie for the pharaoh? I ask because each other fear causing aura I've encountered (plus 1e mummy) provided a save of some sort for the fear portion.

Third, does the immunity apply only to the one source, or immunity to the ability, regardless of the source?

Please also let me know how you interpret it RAW, as well as RAI.

It does seem like two distinct effects with the immunity only applying to the latter, the paralyzation w/ save.

Fear's a gimme, much like Dirge of Doom. This is part of the reason I think the immunity doesn't apply to it. It gets odd otherwise.

It's immunity to the ability regardless of source, so Mummy Pharaohs don't work well in multiples (and it'd be too powerful if they did). This is an intentional change from the playtest where immunity only worked for the one source. That took a lot of bookwork and tracking in large combats. Now if it's immunity to only the one source the ability will say so.
