The daylight-tolerant trolls are referred to as "Hill Trolls from Gorgoroth" in "The Black Gate Opens."

Question:

Are there daylight-tolerant trolls running around in the wilderlands?

Do all trolls turn to stone in the sunlight or just stone trolls?

According to the Olag-hai description in Decipher's "Lord of the rings" RPG they don't turn to stone when sunlight touches them, but they don't like it either so suffer modifiers while in sunlight condition, unles the Dark Lord is in direct control of them, then they suffer no ill-effects what-so-ever.

Now, that being said, I am not sure how they are/will be set up in TOR. Our Comapny fought a Troll in one of our early games, and it just about killed two of the party...I shudder to think about facing off against an Olag-hai.

That pretty much covers things as I recall them.

Operating on their own recognizance, rather than being infused with Sauron's will, any of the former "Denizen of the Dark" sunlight-modified creatures operate at a reduced capability while in direct sunlight. In gloomy conditions (bad weather or within forests) the penalty is removed and they operate at full capability.

When Sauron's will drives them, they are in a kind of battle frenzy where they ignore natural lighting conditions entirely and operate at full capability. They are still susceptible to magical lighting affects per the Lantern of Balthi, Gandalf's Ray of Sun, etc and probably act and re-act from such attacks as though suddenly illuminated while in the dark.
