Rabit's page

I've been running a group through one of the adventure paths, and the PCs are about to encounter a villain weilding a rod of lightning and thunder. (Leaving it vague to avoid spoiling anyone - it doesn't really matter for the question, anyway. :-) I hadn't looked closely at that rod in the past, and noticed something when I did.

Thunderclap: Once per day as a standard action, the wielder can cause the rod to give out a deafening noise, just as a shout spell (Fortitude DC 16 partial, 2d6 points of sonic damage, target deafened for 2d6 rounds).

On one hand, it's "as a shout spell", but the shout spell explicitly does 5d6 damage (not 2d6 as listed for the rod of lightning and thunder). So is that a change specific for this item or a typo? If it's a change, how much damage do crystal objects/creatures take? For the spell, it is based on caster's level. The rod's CL is 9th so I'd assume 9d6, but if the base damage is reduced, is this, also?

(And I'm assuming the answer applies to the Thunder and Lightning ability, as well?)

Any assistance is greatly appreciated!

Need a rules interpretation, and searching hasn't shown anything, so I'm probably missing something obvious. :-\

Corrupting Touch says "Multiple touches do not stack, but they do add to the duration", but it doesn't say what happens if a subject of the ability was already shaken by another effect.

Grave Touch is specific on this, saying, "If you touch a shaken creature with this ability, it becomes frightened (see page 567)", but it is also slightly different in effect so that might be something it has in place of radiating evil.

Anyone know the official ruling on this: Does Corrupting Touch escalate an existing shaken condition to frightened?

Thanks!
