I was cleaning up Wheloon today to finish my monthly ETR+RR cycle, and the Shadar-Kai Assassins started saving my earthquake. Quite often - maybe 50% of time. Yesterday only certain champions stood up to my earthquake, and as far as I know, they're immune to knockdowns. Reapers and other mobs stayed down as usual.

Alarmed by increase in healing requirements, I looked into my earthquake spell, and I noticed that it shows up as FORT save. Wiki agrees that it is supposed to be REF save.

Has anyone similar experience? Has the tooltip always shown up as FORT save, or is it just me having delusions?
