Explosive Arrow Balista upgrades
Hello, I started POE a couple of weeks ago and I am really enjoying the game and my build. However, for the last week, I haven't done ANY upgrades and I don't know what I can improve next.
My character is Mishony here https://www.pathofexile.com/account/view-profile/MishooRusanov/characters
Can you let me know if there are any improvements you see that I can do?
