Herald of Blood Wont Activate

I have 140 spirit, definitely have herald of blood toggled and it lets me toggle it, but it never appears in my auras and for sure is not actually working and is not just a visual bug. WHy???? All requirements for sure met have strength, have tried lower level spirit gems just to see if the one was bugged I am stumped. Had herald of plague active first but tried turning off all other auras and there was no difference. Am playing Pathfinder. No second weapon set even equipped but tried equipping one and toggling for other weapon set too and no change.

Switched to my Druid and he cant activate herald of blood either

Help please it won't work on any of my characters and I feel like a gimp on my Pathfinder.
