Hello,
I recorded this to show someone the build, I hope it can help someone decide to play it because it's really fun.
Showcase : https://www.youtube.com/watch?v=KFanPLiOYKQ
Budget : Headhunter + 40 div (HH bought for 26div)
POB : https://pobb.in/JGKLZQNNY8wh
The build is extremely tanky and great at legion even without HH, in fact I did legion for ~30 maps before I bought one and had no problem at all.
You need to be aware that single target DPS is low but in a mapping context it's no problem.
