Not a flashy build, but is more than enough to survive 99% of content in the game and to flex on all your squad members with your big red number.

You can still fit all the mods you need (some utility included) without spending an Umbral Forma. This build assumes you have maxed out your umbral mods.

Two things of note:

• The aura slot is polarized for Steel Charge to take advantage of the bigger capacity.
• [Adaptation] can be kept at r0 since [Inaros]' EHP will give you plenty of a buffer to stack the damage resistance.

If you decide to spend an Umbral Forma you can additionally rank up Adaptation to r10 and/or change aura+exilus to your preference.
