After so many years of inconsistently trying for this mount, it has finally dropped for me.
I will never have to step foot in ICC again. Yes, I am sorry/not sorry, this is boasting and also a big sigh of relief.
Now if you’ll excuse me. I have some laps to run around Dalaran now.
Big grats 
On to the next mount. Maybe?
Grats though!
Grats!! I was relieved of my 9 year tour of ICC only a month ago. Welcome to pony club.
Thank you, it dropped on my monk and he was the first toon out of about 17 I had planned to run thru ICC… the first one I was like “NO EFFIN WAY”
Ashes next. I couldnt handle farming both at the same time, the travel distance is a big factor, now I can focus on the next one. SL has been very lucky for me with old mount farming
Transmogs?
op is lying because everyone knows you can’t see it that’s why it’s called invincible
its fine. ive had it since 2008 when it was a guaranteed drop
… 
Well, it will be a while before I go back. I have farmed it so long I have all the heroic stuff I want, but I do like all the colors for the paladin and mage sets. But I have everything I want from there by now.
Open up All the Things’ options → General → Check the box “Account-Mode”
Hate me later >:)
Congrats! I obtained Invincible’s Reins several years ago. I cannot recall which expansion. Probably MoP or something. I do not know. I solo’d Ulduar for years later though. I think I only got Mimiron’s Head like on or two years ago? Something like that. Maybe three years. I can sleep well at night now.
It’s a myth! A myth, I say!
MYTH!
Just like that damn baron’s mount.
Myth, lies and poppycock.
hrumph
I was a non-believer for a good long time as well. I actually spent a good hour, hour and a half debating whether to even bother. “I know it isn’t gonna drop and I will have sat through that RP 17 times for no dang reason” is what I was thinking and BOOM first toon.
It’s like the lottery, you gotta play to win. I am not saying that like it’s a good thing! xD
Yay! Grats! 
How can you see when it drops if its Invinsible did you use sonar or echolocation??
Congratz Nui! I hope the mount will drop for me soon!
Mimiron’s Head dropped for me 1/27 and Invincible’s Reins dropped for me 4 days later.
After so many attempts on alts, I was stunned. It was my best week in WoW ever!
Grats!! I got mine a few years ago, and it also dropped for my monk, oddly enough. Hope you have good luck for your next mount drop!
Op you know your gonna play wrath classic again and raid icc again don’t lie.
Grats I also know the feeling of finally never having to farm that unseen mount anymore enjoy it one of the best in game.
