To be honest, most of the responses here are just dumbbbbbbbb. lolz I'm not gonna address anyone directly or refute your arguments, but I'll answer your questions and concerns, Mikal.

If you're actually trying to build armor sets around a single sword, naturally you're gonna want to get both Wolver lines, since those best complement your sword. Except that's sorta dumb. :D Generally, most people will have 5-10 5* weapons before achieving 'game over', so I'd first off suggest you get more weapons and experiment.

Rock Jelly is a decent, standard set, but I'd suggest you don't make that 5* (except the helm as a costume). It's really hard to say what you should get, since really, I don't know what you like. Faust is awesome for dealing with slime levels because of the great knockback and the damage bonus, but Avenger is great for zombie/construct levels, pretty much for the same reason.

Ultimately you want to have at least one shadow weapon, one elemental weapon, and one piercing, so that you cover all the damage types. And after you decide which weapons you like most, that's when you should decide what armor sets to get. I really can't tell you what to do with your SS, since that was a hell of a battle for myself. DA is great for Vanaduke, but GF is great for any and all slimes (gremlins too I guess). As for Antigua, if you end up crafting it, make it an AP, since Sentenza is useless and awful. But Needle Shot is just as good for FSC (and better on Vanaduke/trojans). I wouldn't recommend you get both, but just one since they serve the same purpose.

So you've got your piercing weapon covered (unless you want a flourish too), which means you need elemental and shadow now. Get a brandish and decide which one (brandish or SS) you want as your shadow/elemental weapon--or get 2 brandishes or 2 sealed swords, idk. If you want to take the gunslinging route, grab a Polaris for the elemental weapon and Shadowtech for the shadow imo. As for bombs, well those are pretty easy.

The hard part is just deciding what you like, so if you have about 10k and some time to waste, pick up the weak versions of pretty much every decent weapon (cutter, alchemer, pulsar, flourish, freezing/fiery atomizer, blast bomb) and do T1, and see what you like from that point on. I myself have been meaning to do that with Cutter/bombs for a while, but haven't actually gotten around to it, so I stick with gun/sword.

Anyway, once you determine what weapon TYPE (gun/sword/bomb) you like, THAT'S when you decide on what armor set to get. If you want to just stick with swords go ahead and grab Vog, it's a lifesaver in T3 (literally), or else go experiment and maybe pick something up from there. Ofc, you have time to experiment once you're endgame anyway, so w/e.

TL;DR get Vog if you're boring, or else experiment with different weapon types and choose armor based on what you like.
