Hitting on abilities and abilities to re-roll success's

[Maddpainting]

I swore it was in a faq but couldn't find.  

If you have a rule to have a rule take effect on a hit that stops the attack (Example, Scourgerunner Lay the Beast Low; hitting on a 6 stops the attack and instead deals X MW's) but your opponent has a rule that yes re-roll successful hits (like Archaon's The Eye of Sheerian; hits of a 6 needs to be re-rolled). 

Does the attack still need to be re-rolled?

The answer is actually on page one of the Core-Rules. Re-Rolls, last sentence:

Quote

Rules that refer to the result of an 'unmodified' dice roll are referring to the result after any re-rolls but before any modifiers are applied.

So re-rolls have priority over other abilites.
