You can replace the umbra's with normale, thats also still pretty viable if you don't want to forma that much,
It greatly reduce's the forma count with 2-3 and will save you time

The following stats will change if you will go for this approach:

You can replace the umbra's with: These stats will change:

Umbral Intensify for Intensify -47% Strength
Umbral Fiber for Steel Fiber -248 Armor
Umbral Vitality for Vitality -330 Health

My two cents:

[Stretch] could be replaced with [Blind Rage] which will change your strength 247% to 346% (but you will have to forma the frame 1 more time and use Madurai on the stretch slot for blind rage)
This will make your globe stronger but it will also make your efficieny drop by -55% which makes your spells cost more its totally up to you what u prefer to use
(Removing [Stretch] also makes your globe smaller which in some occasions is not a big deal, but sometimes a bigger globe does the favour)

If you really don't give that much about spell cost you could remove [Streamline] for a [Augur Secrets] to add 24% ability power topping your Strength to a wopping 370%! so you will have an even stronger globe at the price of more cost obviously

Im not that familiar with arcane's yet that's why i havent added them but i would say add according what suits with your playstyle or does work with this build! :)

• This build has been mainly made with the focus on Globe (the other Ability's are still viable with this build only minus is the freeze duration)
