[Rubico] is so old fashioned... Here is my [Redeemer] build for eidolon [Hunt].

Basically, it's a heavy attack oriented build. You look at their synovias, you shoot, BOOM! Next.

Once big boi is down calling for little bros vomvalyst, you start stacking your combo counter up to x12 (it grows quite fast with [Redeemer]), and when he's vulnerable... BOOM! Next.

This build can also be used to tear down some high level enemies as it deals a ton of damages. I personally use it on liches, sortie bosses, long duration runs... With a pretty satisfying result.

If you manage to get your hands on a riven, you can remove [Gladiator Might], and aim for a crit chance, initial combo, and either crit damage or damages as a 3rd stat, and, if possible, a negative that doesn't harm much.

Post Helminth update: [Redeemer] is back! Check out my ripdolon Zephyr build for a counter measure to the fall off nerf that went live during Scarlet Spear.
