Howling wind works fine for me, i was solo lvling all day today and managed to get 2.5bars on average per elix with the help of howling wing. I have 405 defence and howling wind at 34/30 reducing attacks by around 1440. I get hit 10% of the time which is really good. I have been killing the blackstones and boggans but with blackstones slightly higher hit ratio compared to boggans.
Seems to be working fine for me
My hw reduces attacks by 1600+
Yet I could not evade a glimmerwing faerie.
Pleased yours is working fine. Hoping mine starts working again soon.
