Idea of this build is to use bloodletter artifacts' bonus to change healing into shield healing. With this and phalanx doctorine we have already "infinite shield" but how do we get shield regen? Well moze have this grenade hit 20% max health heal (vampyr) which most builds use but with cloning maddening tracker and bloodletter you can use this for shields. When we combine our shield heal with doctorine and force feedback we actually can get +21% max shield increase per kill (with my class mod giving the skill +2). And force feedback gives extra 10% of max shields per critical kill.
!Maybe the most important thing to take into account is to get atleast +2 on thin redline so your hp value is always "1" proccing always desperate measures skills' full potential and you gain +100% shields so it works like deathless artifact!
Only thing you "need" here is redistribution to get "infinite" mags and rest of the skills are optional although I've picked what I think would give you the best dps . You combine this with the before told grenade mod and you can usually sustain you mags without having to get class mod to boost the skill. The only weapon we use on moze is usually plasma coil you can use launchers or res or some other gimmicky weapons for movement speed etc. Plasma coil shreds through every boss in the game with this build without having to worry about ammo
This tree gives moze great splash damage with incendiary bonus which is great because we only have electricity and radiation in plasma coil. The idea of this tree in this build is to get vampyr as first priority torgue cross-promotion to boost means of destruction which is must have to get infinite grenades to heal mozes' shield and give ammo to your plasma coil. Action skill cooldown skills are 100% optional since this build doesn't use action skill for anything else than triggering anointments so that's why I decided to use some points on those.
We actually use iron cub as our action skill because it doesn't interfere with our gameplay, you can use iron bear if you want to immedietly proc some anoints. As guns I've picked nuke because I have a feeling that it's good for mobbing but use whatever you feel most comfortable to use.
Weapon: Plasma Coil/non dlc: backburners,m preferably with consecutive hits anoint (radiation variant works the best with atom balm) Shield: Infernal Wish/non dlc: the transformer or front loader Grenade mod: Cloning Maddening Tracker Class mod: Bloodletter (honor guard enhanced variant feels good for me) Artifact: The Pearl of Ineffable knowledge/non dlc: atom balm deathless
