Ok. I'm going to pull up the EXACT text from the High Elf Faq with respect to the Pendant vs the Kraggi Reroll for Thorek which should be enough precedent to make it that you essentially reroll ALL dice for Armor of Damnation vs Hatred exactly once. IE the hatred makes you reroll all the misses and those misses that become hits stay hits, and rerolls caused by AoD that become misses stay misses.
Q: How do the Pendant of Vengeance and Thorek Ironbrow's Kraggi re-rolls interact?
A: Remember, a dice can only be re-rolled once, so the two never interact at all.
In other words, the Pendant forces you to re-roll successfull rolls and Kraggi allows you to re-roll a failed roll, but in both cases you cannot then re-roll the second result.
So effectively Hatred/Hammer of Sigmar and the Armor of Damnation do truly effectively just cancel each other out and you're effectively just rolling to hit normally without the re-rolls.
