One Umbra Forma Support [Oberon]

Howdy welcome to my Oobooroo guide.
Right off the bat I play Oobooroo for the Renewal (Iron Renewal) and Perma Armour striping.

Things to Note

Allies who enter your Hallowed Ground with Renewal on Gain an addition effect called

Iron renewal

. These allies are healed but also gain additional armour based on Oobooroo's power strength
(with this build the allies are healed for 82/tick and gain 412 additional armour)
(if you choose to not use [Power Donation] you will have a true 236 Power strength so those numbers will go up.)

Additionally
Oobooroo and his allies will gain status immunity when standing in Hallowed ground.

Reckoning

Anyone who plays [Oberon] should know that his ultimate Reckoning Applies a Radiation Proc as well as a knock down, but did you know:

Reckoning deals additional damaged to targets already effected by a radiation proc

Hallowed Ground Deals radiation damage but with a status chance to proc radiation proc
ALSO
When enemies who are standing on your Hallowed Ground are then hit with Reckoning they get a percentage of armour (based on Power strength) stripped from them indefinitely.

Helminth

Currently still working this one out, honestly at the this point you could easily go for Roar or Warcry because both are goo support skills, and this build will have the Strength and some duration to help with those but I am also thinking maybe Condemn or even Empower
I think that one is really up to you and your play style if you like this build as is chances are you will like my play style and those are the four skills I think would benefit this frame and your Party the Most.

[Power Donation]

My thoughts on [Power Donation]

First off this is how it works

you lose 30 Power strength but the other 3 members of your group gain 30.

I like running this because I like making those around me stronger, however if you play with a group of friends (min 3) I recommend everyone running Power donation.
Here's the math and the reason why:

1 Player -30 strength to self +30 everyone else

2 Players -30 to self +30 to everyone else
So in a duo the aura would cancel
.....but a group with 4 (the 2 randoms not running power donation) the 2 random players gain +60

3 Players -30 to self +30 to everyone else
So in a trio you're group is gross +90 strength, however it's net +60 strength,
.....but in a group of 4 players (the one random player not running Power donation) 3 of you are getting +60 and the 4th random player is getting +90

4 players -30 to self +30 to everyone else
now all players have -30 strength to them selves but are grossing+120 netting +90 strength

So now everyone has +90 power strength
and also this is V(Madurai) polarity that gives +18 mod cap like [Steel Charge]. Giving you just enough mod cap to only have to umbra Forma once.

Note: the mod [Coaction Drift] Does not effect this Aura at all.
