[Harrow] has two abilities that have their range entirely based on your affinity range rather than mods. This build attempts to abuse that along with a subsumed ability that synergizes with the build stats.

Dispensary is chosen because it fits with Harrow's general playstyle of being a support frame. Quiver and Null Star also work if you're focusing on self-preservation. We replace Condemn because we don't have the range to ever use it.

[Enemy Radar] helps the entire team to find enemies. The playstyle of the build forces us to sometimes chase down stragglers. It can be replaced with other auras to suit your general playstyle or team composition needs.

Augur mods and/or [Brief Respite] allow [Harrow] to spam Penance. The ability isn't able to be cast when you have zero shields so this allows you to loop the ability during enemy downtime until you hit the duration cap.

[Natural Talent] helps us to curb the long casting times on all of your abilities. It isn't suggested to cut this mod because your build won't work anywhere near as fluidly.

Arcane Energize and Arcane Aegis are both flex arcanes. Energize might be redundant if you're constantly able to proc Thurible. Aegis just gives you a small chance to become nearly invincible when it procs. Either can be replaced with arcanes that suit your playstyle.
