Is Shriek of Milos still bugged?

I'm a returning player and according to Fextralife (yeah yeah I know the drama surrounding the website) one of my go-to weapons, Sword of Milos, is apparently bugged. Its roar only applies a 5% debuff instead of 15% even in PvE, does anyone if this is still the case? And is there a way I could test in game?

Patch 1.12.3 was last July, surely it has to be fixed by now, right?
