You don’t need Kraken on Dunefiend setup, believe the whole map needs rethinking.
Taking Basilisk Mark will let you know hardcap Nidalla’s Justifiable Ends for -1.8 s to Shadow Strike and you can still get Path of The Three at 21/12 for 15% CDR and put 1 point at least to Dual Blades for 4% phys res.
i would take Mythical Slithscale Legwraps and sacrificed Merciless Repertoire (keep it at 20/12) and put those points elsewhere.
this is how it was done before, but with more focus on acid damage than poison (as you do here on Nightshade Reach setup with Dervish).
