help with katabasis duelist build

first time with frost blades of katabasis and mageblood. can someone tell me if i'm doing it all wrong? do i have my flasks set up right? also, if i were to try to upgrade something at this point, should i do the claw or try to do a cluster jewel set up?

Your gear is really good but I have some comments:

- Your hits can't be evaded so those accuracy passives can be dropped. Precision can be dropped until you get your Watcher's Eye.
- Your charges are always max and you aren't using brutal charges. Charge duration passives can be dropped. You also don't need the mark mastery which helps you to gain frenzy charges.
- Spell suppression chance is too low. Temporarily take the suppression mastery which gives you lucky chance to suppress until you complete your gear.
- Understood you are using warcries to gain rage, but maybe, just maybe, spending 10 points and inducing socket pressure for the whole setup may not be worth it. Those points can go to your cluster jewels.
- If you can take the risk, drop your life flask and equip a tincture. Find a prismatic tincture with good roll and self-craft it with increased effect and penetrate elemental resistances. Your Steelskin makes you nearly immune to bleed. Corrupted Blood immunity can get from jewels. Or perhaps the ruby flask shouldn't be there. I'm not sure. You can get creative with Purity of Fire or other stopgap measures until you can balance your resistances.
