Heal Scrapper
A Minstrel's heal Scrapper on double Shortbow — protection that cleanses, 
Barrier from wells, and 
Monk boon duration.
The gyros here are wells. 
Bulwark Gyro and 
Purge Gyro pulse where you drop them and stay there, so you cast them into where the squad is going, not where you are standing. That is the skill in this build: guessing the push one beat early.
Why these traits
Your cleanse runs through 
Protection. 
Reconstruction Enclosure grants it to nearby allies every time you use your heal skill, 
Expert Examination adds it on your 
Function Gyro and on 
Bandage Self, and 
Anticorrosion Plating cleanses conditions from every ally you hand it to — so protection is not mitigation here, it is the cleanse engine. The second engine is finishers: 
Blast Zone drops a blast finisher when you press Bandage Self, 
Kinetic Accelerators turns your function gyro into a blast finisher and pays boons to allies for every combo you close, and 
Chain Reactivity gives you Barrier for each finish and a shared one every third. 
Soothing Detonation heals nearby allies on any tool belt skill, and 
Health Insurance raises your healing to others while you are in 
Med Kit — which is where you will spend the fight. 
Autodefense Bomb Dispenser is the one selfish pick: a smoke bomb when you get disabled.
Gear reasoning
Full Minstrel's with Monk — healing power, plus boon duration that lengthens every protection you hand out, and your protection is your cleanse. Both 
Transference raise healing to other allies by 10%, and 
Karakosa heals nearby allies whenever you close a field with a blast finisher, which is exactly what Blast Zone and the function gyro produce. Double Shortbow means the swap never changes your skills: 
Essence of Living Shadows heals and cleanses, 
Essence of Animated Sand grants Barrier and might, 
Essence of Borrowed Time stuns while giving allies 
Superspeed. 
Frenzy and 
Life only trigger on kills, which on a build with no offensive stat is rare — those are the two slots to change first.
When not to run it
Zerg only. You have no offensive stat, no damage traitline and 
Supply Crate for an elite; away from a squad there is nothing here that kills anything. Inside one, if the group already has cleanse and Barrier covered and what it lacks is pressure, bring one of our power Engineers instead — Holosmith or Amalgam.
