So I just completed the achievement “Chronicler of the Haranir”, which also completed “That’s All Folks!” and then “Light up the Night” also. So, I got 3 achievements at once. So, I was wondering what is the number of achievements you all have gotten to pop at one time? I think 3 is the largest for me. I remember 2 achievements at once, but never 3.
I think I just got 5 for a Tier 5 Ritual Site with all the extras (Tier 5, 8 challenges, Tier 5 + 8 challenges, Tier 5 + 8 challenges solo, and Tier 5 plus at least one ember).
That last one killed me twice until I realized it only required one ember, not all four. The end boss of the Broken Throne (Zul’Aman) ritual site was unbeatable at +60% damage and health, but manageable at just +15%.
Ritual sites or logging in on patch day and getting barraged.

I’ve gotten way more than three at once, but I think the UI only shows pop-up toasts for up to three.
Did every achievement for Daggerspoine Point Ritual Site plus general ritual site achivements in one go think it popped like 10 to 15.

You can get a good half a dozen if you do the first boss in Ulduar while leaving all towers up and going straight for the kill with a catapult.
Something similar happens if you do Yogg-saron with no keepers after having killed 9 adds at once on phase 1.

Yeah, Tier 5 of a ritual site you haven’t touched in a group of at least 3 with every challenge active and killing no obelisks will result in somewhere between 11 and 15ish achievements. I did this with a couple friends early last reset with Broken Throne and the chat spam was crazy.
