(pretend there’s a 4th forma there and power drift in the Exilus slot since that’s what I’m planning to do for it just for a smidge more power strength)
Range is useless in fighting Eidolons since you can’t use thurible or condemn to chain enemies or get energy. And Covenant goes by affinity range by default anyway.
When timed right when an eidolon unleshes it’s proc wave upon a limb being destroyed, covenant will last long enough for you to get his shields back to and wail on his limbs again.
I pair my Harrow with a euphona prime built for crit and use mainly that for the fight.
It’s been pretty effective thus far in the hunts I’ve used it in. Though I hope to try it out with a chroma on my team with the updated vex armor. I’m curious to see what kind of damage numbers the covenent crit multipliers and the furybuff together will yield.
