Demonstration/Test run with 3 piece safi 2 piece Ranging brachy (GS-AT Velk)

Doing a challenge that is not really challenge cause most people had to do this before and equally like me.
Basically to do non end game builds against arch tempered velkhana, im using a 3 piece safi and 2 piece ranging, i did the build and it worked quite well but its quite risky as well.
