FT Build for Open World/Dungeons/Fractal ?
Flamethrower, Vuln stacking AND goggles? Let me see…
Best I could come up with. You’re not going to do much vulnerability without spending most of your time with either bomb or grenade kit, and I’m thinking that is kinda what you are trying to find an alternative to.
The real appeal of Flamethrower is self might stacking with Juggernaut, hence the Strength runes (which can be replaced with Hoelbrak if you worry about conditions, or Flame Legion if money’s tight) You might also decide to drop Tool Kit for Elixir B (Fury from B means more crits from the FT AA, which means more chances for vuln) If you feel really lucky, you can also take Elixir X as your elite and hope you get the tornado transform, which is now a constant lightning field with whirl finisher, which can apply vuln if the bolts hit.
Of course, I could have been a real smartkitten and posted the latest ’nade build meta instead, which IIRC does use flamethrower, but only long enough to drop napalm and blast it with Flame Blast, before going swapping to something else. Just take Utility goggles as your Stun break and it will fit all three points (that is, a vuln-stacking build that uses FT and Utility Goggles.)
