Hello, im new in game my first character. I tried read guides and got a build

problem is i die a lot :( cant even do lvl 70 heist.

what do you suggest? i could save more than 6 exalted orb by farming maps. i can buy gears vs.

seeking for your help :)

First thing I see is that this POB is in version 3.11 lol. Outdated tree if you are building off of this.

I'd just recommend following Kays Spectre guide which can be found here
