Jeweling Concept: Eye Of The Beast + Obelisk Core = Mass Inversion

I've been looking at a few ingredients lately, and I noticed some sort of interesting synergy between two ingredients: Eye of the Beast and Obelisk Core.

If you position ingredients this way:
Eye of the Beast 1: middle right
Obelisk Core: top right
Eye of the Beast 2: bottom left

...you end up with this:
2/4 Mana Regen
-202 Durability
+80 Intelligence Minimum
Middle left and bottom right slots have -160 effectiveness(ingredient inverted and multiplied by .6)
Top left slot has -280 effectiveness(ingredient inverted and multiplied by 1.8)

This format warrants experimentation with Jeweling and making some pretty broken 2/4 Mana Regen rings.

Example:
Top left: Pristine Claw
Top right: Obelisk Core
Middle left: Pristine Claw
Middle right: Eye of the Beast
Bottom left: Eye of the Beast
Bottom right: Pristine Claw

Result:
2/4 Mana Regen
120 to 150 Raw Spell Damage
-90 to -120 Raw Melee Damage
-112 Durability
80 Intelligence Minimum
Getting called OP by @Stycore

Feel free to experiment, and let me know if I messed up and this idea is really just stupid.

EDIT: Eye of the Beast got nerfed and it has -90 durability and +40 Intelligence Minimum. Double Eye of the Beast may not work out well but using just one could make some fun stuff.

EDIT 2:
Made another example.
Top left: Naval Stone
Top right: Obelisk Core
Middle left: Naval Stone
Middle right: Eye of the Beast
Bottom left: Eye of the Beast
Bottom right: Pristine Claw

Result(could be good with spellspam builds that don't use water damage)
2/4 Mana Regen
24 to 30 Spell Damage
-18 to -24 Melee Damage
-20% to -32% Water Damage
-77 Durability
65 Intelligence Requirement
(these numbers are fucked up and I'm gonna fix when I have the values right)

EDIT 3: Fixed some calculations

EDIT 4: Fuck this doesn't work anymore

 

this one looks pretty OP

 

Yeah, but -120 durability and 80 intelligence required. This could probably only fit on a necklace, but then again, you don't see 2/4 mana regen OR 100+ raw spell very often on an accessory.

 

true, but 80 int is no problem at all if you're going full water
also is -120 a lot? do you know what the base value on this would be?

why only on necklaces?

 

I really don't know how much durability an item has with base materials. I'm guessing that it should be enough when using 3-star Voidstone Gems and 3-star Starfish Oil though. Pretty sure at lower levels you can get up to 200 durability with 3-star materials, but then again I could be quite wrong here.

 

yeah thought so
