FrostBorn: Helheim Rift -Oricalcum Farm 1m30s

Enter sneakly into Helheim Rifts and farm your Oricalcum in 1m30s. Do and repeat.
Just enter at the very start, this not working if Helheim Rift opened +30 secs/1min.
If you are not going to pvp and you don't find a vein in 15 secs from the entering, just leave the zone!
If not, search for it and hope they will not find you! Bad Boyz around ready for you!
