Question about Great Weapon Fighting in D&D

[DarklordKyo]

My Paladin took the Oath of Vengeance, and he's a greatsword wielding arbiter of justice. Naturally, I got him the Great Weapon Fighting style when he ding'd the right level to get it.

According to the description, it allows me to reroll a damage die if I get a 1 or 2. Since it doesn't specifically limit it to one per roll (assuming I'm reading it correctly), would it allow me to reroll both if I were to get snake eyes? (or all, if Smite, Hunter's Mark, and, eventually, Improved Smite are taken into account), or do I have to just limit it to only one?

1. Yes, you can re-roll any number of dice for your weapon once. It was written with the 2D6 weapons in mind.
2. It's only the weapon damage. No smite or hunter's mark re-rolling. I can't remember if that's text or errata, but it's the case.

Not even the static 1d8 from Improved Smite huh?, gotcha.

No, but Improved Divine Smite's bad wording hides the fact that in addition to adding 1D8 to all attacks, (Including smites) it adds a second D8 to smites, making a first level Divine Smite against a regular opponent W+Mod+4D8, and a fourth level slot (Fifth level slots don't smite harder than 4th) against something unholy W+Mod+8D8.

Does this mean it's added on to Hunter's Mark too? If so, I really need to get some more d8s.

No, just +1D8 to Melee attacks, and a further 1D8 to smites. If you smite a hunter's marked target, hunter's mark only proc's for the usual D6 on top of everything else.
