I know I was memeing on the dps a little doing it in ideal conditions.
But for those that want to enjoy a 1370 artillerist on a budget, get 3x3 engravings with max firepower and barrage with either keen blunt weapon or grudge or hitmaster.
Don't neglect tripods, use the transfer tripod inventory trick to get 6 cheap guaranteed lvl 4 tripods (+3 on gear).
Your most important tripods are.
Also you will need your 2 best wealth runes for forward barrage and flamethrower.
Now enjoy the dps of an average 1415 char on a budget 1370 arti.
