Large Soran'ruk Fragment Drop Chance? (Quest for Tank Rune Warlocks)

Hey, I am super hyped to get that tank rune but was wondering when Wowhead says the “Large Soran’ruk Fragment”'s drop chance is 0,83% is that accurate? Or is that based on old Wow Classic 2007 data?

Thanks in advance. Really hoping for the latter. It would be a big bummer if that actually was the drop chance… :confused:

EDIT: I can confirm it is a 100% drop! YAY!

just to make sure you need the Warlock quest for it to drop.
as the mobs are usually killed by all sort of people it is not tracking reliable.

It is not a 100% droprate. Just ran an SFK and we had to double back and grab extra mobs that are on the right hand side of the staircase.
