When you cast Revelation of Script and Storm of Spirits, can you use the +3 bonus to Lore checks that RoS provides to further increase your combat check? I'm guessing no, since RoS only provides a bonus to Lore checks and you use a combat check with SoS.
I think your guess is correct. Using Storm of Spirits is a Combat check, not a Lore check. Even though you use your Lore stat instead of your Fight stat when fighting, it is not technically a Lore check. I hope what I'm saying makes sense. 
I concur with both your assessment and that of Mi Go Hunter, as it's a Lore Check which drives the Revelation Script, whereas you're using the Lore stat in lieu of the Fight Stat to determine Combat Checks.
Revelation of the Script doesn't buff your Lore stat; it only gives a bonus to Lore checks.
Had RoS said: gain "+3 to Lore until the end of this phase", then yes, the combo would've been valid.
Thanks everyone! Dam, I should really check out BGG more often. Not that that thread resolved anything.
Heh, I guess this is pretty much the same issue as the Sledgehammer's bonus to "Fight" vs bonus to "Fight checks." Of course, that one's ambiguous too.
I'm going to say that it's allowable.
In most instances, you're making a Combat check, which is a special type of Fight check. Very specifically when using this spell, you're still making a Combat check, but in this case instead of being a special type of Fight check, it's a special type of Lore check. Which means it's still a Lore check. So anything that bolsters Lore should boost the effectiveness of this spell.
Take note that since the "attack" portion of the spell is not a "Spell" check, you can't use things that add to spell checks (Like the Glass of Mortlan) to make this spell more powerful.
I'd allow it, even going so far as saying that you can use RoS against the Dark Pharaoh monster without SoS. It seems like Lore replaces the Fight for the combat check, making it seem like instead of thee COmbat Check being a subset of fight, for this combat only, the Combat check is a subset of a Lore check (maybe even allowing a usage of skills like Library Use and Lore).
Or...something like that. Either way, I hope it doesn't come up in any game I play :-x

Well Tibs, I think you convinced me otherwise. It makes sense: anything that adds, for example, +1 to Fight checks would add to combat checks as well. So using Relevation to give +3 to Lore checks would increase the Combat check for SoS. Thanks for clearing that up. 
No problem. The confusion occurs because we're used to associating Combat only with Fight. When against the Dark Pharaoh or when using Storm of Spirits, just pretend that Combat is normally a subset of Lore.
So then, to modify or boost such an attack, you could use things like:
But not:
That ruling seems to imply that the Sledgehammer gives you a total of a +4 bonus to Combat checks. Since bonuses to Lore checks also affect Combat checks for RoS+SoS, then bonuses to Fight checks also affect Combat checks for the Sledgehammer, right?
Ordinarily avec, you'd be right. But this was just an oversight. In the particular case of the Sledgehammer, the combat and fight bonuses are independent. If you're using it for a non-combat fight check, it gives you +1. If you're using it for a combat check, it gives you +3. It never gives you +4.
Thanks Tibs

Ha, and here I thought you had special posting rights, or something.
Nope, I just learned a trick or two 
NICE!
When you roll lore, its a lore check.

I prefer sarcasm, personally
