Disclosure has a specific list of enemies, stated by IF in exchange for 9 Reward Dice. I highly doubt that's incorrect given the price. The actual list is a bunch of Foemen (based on Infusions), a Pursuer, and all draugr, trolls, and giants within a certain radius (based on Realm). Plus other monsters if the local spirits dislike you.
So no, it's not just Draugr and I never said it was. I was saying that because of Horra's Draugr Army, it would have been more lethal than usual if done when we originally considered it, since it attracts all nearby Draugr among other things. After Horra's death...we have no idea how many trolls or giants there are nearby, which makes it a bit dicey to say the least even sans Foemen. Especially with Drysalt around and likely recruiting a bunch of Trolls (Drysalt himself would likely be immune, but just the number of trolls involved is probably wild). We need to worry a lot less about trolls now than we did then, but have other concerns.
Basically, I see no need for Disclosure to have extra secret conditions that make the huge Reward Die expenditure meaningless to be as dangerous as it has been presented.
