I'll tell you a secret,
And you'll call me a liar.
I'm deleting Steel Path mobs,
With a freaking Grimoire!
Was the poem any good? Seriously though, I've been hearing complaints about how bad it's damage is without armor stripping, and realized people are falling for the same trap everyone fell for with the Arca Plasmor. Yes, it's status chance is higher than it's critical chance. No, it's not worth the pain and effort investing status mods into a weapon with pure electric damage. Save yourself from a massive headache and pursue Grimoire's crit potential.
If you're curious about my build, I'm running it with a Secondary Kinship arcane on my Wisp along with Thermal Sunder and the Thermal Transfer augment. By buffing the squad I can easily push the Grimoire into orange crit territory. There's other ways to squeeze out big crits of course (Harrow comes to mind), but this is the build I'm having the most fun with right now.
Hope this post helps you have fun slinging spells!
