Archaon re-roll 6s and core rules confusion

[Zanzou]

Let me first state that I realize that warscroll rules take precedence over core rules, but hear me out. Archaon forces hit rolls of 6 against him to be re-rolled: "Re-roll hit rolls of 6 for attacks made by enemy units that target this model."

 AoS put in a rule to ensure that no matter how debuffed a unit is, it always has a chance to hit: "A hit roll of 1 before modification always fails to hit the target, and a hit roll of 6 before modification always hits the target." 

 

Two questions. Firstly, since Archaon's ability does not specify whether the hit rolls of 6 are specifically natural or not - but the core rules state that natural 6s go through "always" - does that mean that Archaon's ability may only work against a modified 6 roll, or would natural 6s still fail to go through?

Second question is to do with re-rolls. The re-roll section of the core rules limits you to only 1 re-roll of a dice, period. However, these rule limitations are in context of phrases as if "getting" to do a re-roll is beneficial:

"RE-ROLLS Some rules allow you to re-roll a dice roll, which means you get to roll some or all of the dice again."

So if Archaon re-rolls your 6 to a failed dice roll, does that still count as your 1 allowed re-roll? 

If the answer to both questions is yes, does that mean it is okay that there are circumstances in which some units will literally never be able to land a successful hit against Archaon?

First question: Archaon's ability is a re-roll, not a modifier so it can only ever affect natural sixes and if a reroll ends up as a fail - it's a fail, no "6-always-hits" applied.

Second question: it does count as a single reroll allowed per die.

Conclusion: it is okay and probably within the intentions of rule writers.

Re-rolls are always done before applying modifiers.  You're right in that you may only re-roll a dice once, regardless of the source of the re-roll.

So against Archaon, this could well mean that some units you could well be needing to roll double six in order to hit him

That makes sense now. Thanks!
