There are a few nodes like that throw an axe when you’re hit but one tree or one skill could have more of that.
Similar to Titan Quest where you had a chance to double hit and stuff in the Warrior tree which I know you’ve took inspiration from. Those kind of effects were cool to stack so you ran around and had a fireworks of stuff going on from a single hit.
Another cool build in Grim Dawn was the cannoner where you could place different canons, sorta like traps but not really. That’s a tree for something in the future perhaps.
Anyways, only suggestions and ideas. you’re doing a great job with this game so im optimistic that you can pick ideas from past great games too.
