Ear-Shattering Rage (No Daze)

[Thani]

[Human, Barbarian 5-7]
I've been using this furor for well over a week now exclusively and even though the sonic damage works as expected and the DC works off Intimidate aswell it applies no daze (and presumably no deafness) even on a failed save. Both in PvP and PvE against various enemies I've used it, seen multiple failures and yet see no results past the sonic damage. At first I thought it did daze but didn't show the effect but enemies who fail the save still continue to attack right after.

Thanks in advance.
