It's time [Harrow] stopped suffering for his teammates alone. This, is the selfish [Harrow] build.

Note: because his 2 and 4 are based on affinity range, you still benefit teammates with them. Sorry, you'll still be supporting teammates on the selfish build :(

For this build we're nuking range and efficiency in the name of duration and power strength. Throw on pillage (or dispensary, but this is a selfish build, so don't do that!) and you end up with an immortal, self sufficient priest that can hit deliciously wonderful numbers.

Pennance gives 104% fire rate with this build, 14% life steal, and 208% reload speed. This combination alone allows for some amazing melee synergy, but it doesn't stop there.

With a small investment, thurible allows for upwards of 30 energy back per kill, allowing you to spam pillage and rip off defenses from enemies, making them easier to kill (74% reduction per pillage cast, it's a wonderful synergy that pairs super well with [Adaptation] to keep you immortal with shield gating.

The final touch is covenant hitting 50% crit bonus with something around 500 damage taken (ala, one enemy hits you during your 14 seconds of immunity). This, combined with arcane avenger, can give a 95% crit bonus, taking any weapon to crit city!

-Primed Sure Footed-
you can't cast if you get knocked down. This mod WILL save your life. You won't notice it, but it will. [Handspring] substitute if you don't have primed sure footed, but swap to PSF once you get it. It's too valuable on a frame that needs to cast to survive.

-Helminth-
I use pillage for this. It keeps [Harrow] alive and wrecking things even between covenant invulnerability.

Vs infested, I swap eclipse on for Harrow's pennance. You could also do dispensary.

-Arcanes-
I like energize as it lets Harrow ramp up faster, but this one is relatively optional.

Avenger- as stated, stacks with covenant to work really well at giving solid crits to even non-crit weapons. (Ohmas get to 110% crit chance, for example).

Pistoleer- is an option if you're using a pistol that would benefit. Fire rate can make ammo go away too fast.
Resistance - if you wanna survive toxin procs, this can be a great option. I use this instead of avenger vs infested.
