Big strength, fat roar with default range. All in all, a good [Rhino] for many things, including gratuitous ultraviolence and, to a limited extent, Eidolon hunting. Most importantly, no ridiculous Strength gimmicks with Conversion mods, so it's appropriate to bring anywhere and use to mindlessly slaughter your enemies while being mostly invincible.
This build has [Augur Secrets] for an incredibly large and girthy Roar. If you prefer a bit more comfort on your [Rhino], swap it out for [Iron Shrapnel]; honestly I don't really think it's necessary, if your Iron Skin runs out to bullet jump away, in any super endgame content I'd rather bring [Revenant], who doesn't have this problem.
