I have no idea how practical this build is overall - all I know is that it's a lot of fun just messing around with.
Relic of the Daredevil gives you a guaranteed crit after every dodge. So:
Solar Focusing Lens, Vent Exhaust on Holosmith
Adrenal Implant on Tools
Energy Rune in second slot of weapon.
Roll, crit, roll, crit, activate forge, endurance spikes back up, fight for a while to build heat, roll, crit, roll, crit, drop from forge, endurance spikes back up, roll, crit, roll, crit, activate forge, endurance spikes back up...
I have no idea if this is an effective way of fighting or if it will actually increase damage overall but it is hilarious. You can't keep it going forever but you can do it for a pretty long time...
