Swap [Primed Sure Footed] with whatever exilus mod you want like [Power Drift]. I like this one since it opens up all the high damage aoe weapons for close quarter usage. You can go whatever exilus mod you want though - which is why I left this slot unpolarized.

Swap out [Augur Message] for any specific mod or augment you need, more tank go for [Adaptation], want another augment you can use that here too. This mod will give you a little wiggle room for getting creative on config slots alternatives.

You are free to pull [Vitality] and [Intensify] for the umbral versions, but to pull this build off you are going to have to use Umbral formas to maximize it to this level (if you wanna use [Primed Sure Footed] I mean) there is no way around it. It is al;o why I left that [Intensify] slot unpolarized so the option remains a possibility in the future to put in a [Umbral Intensify] without having to forma over it and waste more time so then all you need to do is drop an umbral forma on top one of the default D slot and swap out [Vitality] for in [Umbral Vitality].

I think [Mirage Prime] is worthy enough to validate umbral formas, but there are other frames that justify it more before this one. Only consider doing that if this is your main frame or you have a backlog of umbral formas for use on lots of projects.

Helminths
4th skill slot you can leave default prism or consider other helminths. I would advise you pick a helminth that helps assist your playstyle and need. Good notables would be Roar (this affects both abilities and weapons while eclipse only affects weapons while in light), Breach Surge it will require fitting in some range mods but compliments her well, Vex Armor (you got eclipse, but this is more of a reliable tanking helminth and you're already a high duration build so it will work well), Dispensary is always a solid skill to be more self sufficient in emergencies. Or just leave it as is. It's up to you.

Arcanes
It never hurts to have energize on any frames that need energy and never hurts to have grace that any frames that don't have high armor or other damage mitigating skills (it just helps survivability). You are free to swap these out for damage focused arcanes though if you just wanna up your damage (arcane avenger and acceleration are solid picks) for non-steel path content especially. Higher level stuff though consider reducing some of those damage focused arcanes for more sustainability and survivability instead.
