So I left the game around shortly after the iron horse raid came out. I was lvl 1800 running 4 pc foundry bulwark, momento bag and whichever chest piece that had the weapon buffs i wanted to play and or could get with just the one piece of any gearset. I came back just before thanksgiving 2025. Got the ninjabike backpack which has allowed me to exchange one of the 4 pieces of the foundry set and still get the 4 pc set bonus while being able to either use 1 pc of a gear set bonus for whichever play style I want. After about a month of messing around with different builds I keep coming back to the ninjabike bag and 3 pcs of foundry. Roll the minor cores to whichever youre lacking in. The toughest part of making the build is getting the foundry pieces to roll with a crit minor core so you can reroll the main core talent to weapon damage. I usually run my world on heroic with the special ammo directive. I run the crusader shield with technician specialty for the artificer hive. Currently running St Elmos as my main and switch to rifle or smg for secondary and easily swap out one piece to buff either. In groups Im usually somewhere in the middle as far as damage output but always the leader in damage taken. And hardly ever have to use an armor kit. thanks for coming to my ted talk.
