Honestly hard to ditch anything from his kit since it’s all really good. This is a blessing and a curse. He’s always going to struggle with Noxes and Infested. I guess you could build heavy Efficiency and ditch Thurible (and Tribunal) for Silence for an anti-Infested build, but I feel dirty even thinking that. VS Grineer, Unairu helps compensate for getting ganked by Noxes.

Anyway, since he has 2400 Overshield you don’t need to build for shields at all. Once you get Adaptation, the shield generation off Condemn will let you tank basically anything, especially on top of shield gate + Covenant. If you want an infinite scaling build, Rolling Guard gives you an extra invulnerability buffer, or you can just run Vazarin and keep Adaptation so you never have to swap around.

If you have Primed Vigor, I would use that mod (Redirection if you don’t), it gives you a bit of a health buffer to survive Toxin damage, other than that shields give him the most survivability. I also play around his 4 augment, which works well with Arcane Pistoleer, since both of those aim for landing headshot kills.

Depending on what abilities you use you Min/Max around your Duration or Range. (His 2 is an additive cap, you have the same upper bound for all builds and can add more time to it by using his 2 multiple times. It is based off of shield sacrificed.)

Condemn Build For this build you want to find a comfortable balance between range for his 1, making it easier to refill shields, and duration so that you aren’t using his 3 as often, and making it easier to maintain his 4.

Pillage Build This build you do not care about range at all, Pillage expands based on duration, and can be collapsed early by activating the ability a second time. The downside is that you do not have a CC ability anymore but you’re now able to armor/shield strip.

Archon Shards: Throw a couple shards into casting speed. The others you can throw into duration.

Other Notes:

• If you want more survivability, you can drop Arcane Pistoleer for Arcane Barrier.
• Try to avoid using Zenurik with Harrow, Inner Might can bug you into a state where you are unable to gain any energy, if you don’t have Inner Might unlocked there is nothing to worry about, but his 3 already generates energy so it’s kind of redundant.
• Madurai has a passive for faster casting speed which you might find useful on Harrow. It also lets you charge your 3 faster.

This is my build.

It doesn’t have any HP nor Shields and instead relies on Overshields, shieldgating, Rolling Guard, and his 4 to survive.

It’s using Molt Efficiency and Arcane Avenger. His 2 was replaced by Tharros Strike for defence stripping.

Absolutely shields because of condemn. Or just run meme harrow and helminth Gauss’ third onto him.
