Iss Boss Jewels Selections

Hi friends, please enlighten me what kind of enhanced boss jewels should an Iss Enchanter use. Not to mention those high end epic boss jewels. I'm just talking about those affordable ones like Istina, Octavis etc...

Istina Earring
Enhanced Octavis Earring Warrior VS Enhanced Octavis Earring Wizard?

Enhanced Octavis Necklace Warrior VS Enhanced Istina Necklace Wizard?

Enhanced Istina Ring Wizard
Enhanced Octavis Ring Warrior VS Enhanced Octavis Ring Wizard?

I know there are better earrings from COC but currently please give me some advice. Thanks.

Enhanced Octavis Necklace Warrior. (Cooldown for BR and other skills with long cooldown)

Enhanced Octavis Ring Warrior. (Physical crit dmg, no need for magic crit dmg of Istina Ring).

Istinea earring without Enhancement (stun resist).

Normal ones: Istina Earring and Necklace, Octavis Earring.

Enhanced (warrior version): Otavis Ring.

For cheap set, a mix with CoC new jewels would be good. In some cases, some enhanced version of Istina earring/ring for mage-type would be good too, but only in particular situations, mostly oly related.

clean Istina neck >Octavis neck Orfen soul + Istina or Octavis or Zaken clean Octavis ring+Octavis ring warrior (this two stack together)
