Requires single umbral forma.If you use an unranked [Umbral Intensify] you will receive bonus to armor and health without requiring this.

Strength not particularly required as it does not affect amount of armor received from #4. #1 is used to stunlock as many enemies as possible.

UPDATE FOR HELMINTH:

Replace Sandstorm with [Chroma]'s Elemental ward. Watch and laugh as your actual health goes to the moon and back. Strength will actually apply with Ward and will increase your health!

Using [Chroma]'s Ward calculations, this should bring your EHP somewhere north of 90K. I haven't even factored in Scarab Armor's bonus - if someone wants to do that calculation please comment. Will test and update with results once I have a spare slot to subsume [Chroma] in.
