Invincible's Reins

Hi all,

Not sure this is the right spot, but there is an achievement attached to the item.

During the Timewalking Event, I received Invincible’s Reins from a cache reward. I was told this is a really rare mount from the Lich King. I noticed several others in Dornogal with it and I checked their Feat of Strength achievement, and they, too, received the item during the same Timewalking period.

Is this something common? Rare rewards that have an increased odds of achievement during special events?

Thanks!

It’s normal, it’s an extremely rare mount so it’s tied to a Feat of Strength.
Similarly, the Reins of the Raven Lord from Heroic Sethekk Halls has the same type of FoS achievement tied to it.
