Jeweling 3/4 Mr Post-nerf

So we all already know about the frozen ghostly essence nerf which now no longer gives mana regen.
This leaves, for as far as I know, only the eye of the beast as a potential mana regen ingredient.
Thing is, it gives -100% ingredient effictiveness to things above and below it. So you can't really stack 'em well.

Also, whilst writing this I found out durability flipping no longer exists, so rip the durability on this thing.

[E] = eye of the beast
[T] = bobs tear
[F] = borange fluff

Spoiler: pictures of items used

[F][T]
[F][E]
[E][E]

This gives the two eyes of the beast above eachother -100% effectiveness from eachother and + 59% from bob's tear as well as the two fluffs. Giving it a solid >50%, meaning that the eye of the beast keeps it's 1/4 MR.
Since durability is no longer effected by ingredient effectiveness, the total stats should be:

3/4 mana regen
-37% spell damage

with -288 durability

-37% spell damage is very harsh for the spell based build that wants to use it, but let's not forget about things like The Specialist barely being effected by negative spell damage or the fact that 3/4 mage spells are not really there for dealing damage, so this is good for melee mage. Things like that.

Moon pool circlet is better in 4/5 scenarios but hey, it's here and it's possible.

 

I always assumed that effectiveness was applied to each item as they had it, then IDs were added, and THEN it was rounded. Under this assumption this only adds up to 2.18/4 MR, which rounds down to 2/4 MR.

 

Someone did testing. Effectiveness is calculated over each individual slot, and (if I remember correctly) is rounded prior to summation.
