It needs a build for auto axe and reflect damage but once the build is on it takes around a minute to get him down, sometimes a bit longer so all in around 2 minutes from point to point.
I'll be on tonight, probably on Private doing it later, if you want to join and die in the room you still get the same rewards. It's better if you die if you dont have the right build because he will focus on you and it takes a lot longer. With the right build you basically stand there and let him shoot you, the damge he is meant to do to you reflects on him and he takes his own shield down, after the shield is down he just sits there for a while so you get the auto axe out and chop him up.
Pretty boring but right now the best way to get mod boxes up to 4*, legendary modules, scrip, caps, weapons to scrap or keep, new armour plans and parts.
On another subject I have jetpack and calibrated shocks (hens teeth plan) for the ultracite armour, I can easily craft you a set with all the good stuff on it....no legendary just the rare plans. I could drop a few mod boxes if you say what you need, I may have some or can craft around 55 different ones now.
