Want a strong frame that can't die?

Whelp. Here ya go, I guess.

The cooldowns aren't really that big of an issue unless you seriously want to spam your abilities, but with the options in [Lavos]' kit, the sheer EHP you can get with this build, and any weapons you're bringing in with you, this build will pretty much cover anything the game can throw at you.

Yeah, I know two Umbral Formas is a lot to ask for, so if you can't afford those, your next best option is to toss out Umbral Fiber and Umbral Vitality for their non-Umbral versions, and change the two Umbral Forma into D polarities for those instead. That way your EHP may suffer, but your damage output won't as much.

Hope you enjoy!
