It’s good because people don’t like casting Wind Devil every 5 seconds. See
I’ve already made a guide but for another game 
However I’m not sure whether these settings should be set just like on those pictures
but I’m sure you have to mess around with
- Outer Ring Binding
- Outer Ring Radius
- Outer Ring Binding Invert
Too lazy right know to confirm these are just like in the guide above but you should be able to figure it out.
Obviously don’t bind Left Click but some Gamepad Button responsible for some skill
Btw Chronicon is such a cool and developed ARPG… If it weren’t for Grim Dawn I would be playing it instead most probably. It also has Double Skill Tree system like Grim Dawn but there every class has 5 trees and you choose 2 of them. Made by a single guy.
