That actually explains a lot..
When you use su war axe/whirpool combo, you will not get as many tornados as youd want. I remember one ladder i played treewarden, and just from feaerie fire the stream of nados was endless.
I was wondering whats up with that. It is hard to tell because whirpool duration is short. So when you hit with it, before you ww, it still releases huge wave of tornadoes in all directions, but when you ww, they stop coming out. Ofc they would have stopped anyway because whirpool disappears, but still. And that is on striking proc.
What is weird though, tornadoes still carry the poison, despite fact they were triggered before you went into ww.
