Your sword selection is wonderful. You still might want to read the end my sword guide for the parts about sidearms and armor. There is no question that BTS is preferable to Royal Jelly Shield for a sworder.

Yes, Snarbolax is preferable to Dread Skelly for a sworder. It will be hard to make it through the Shadow Gloaming Wildwoods in Vog Cub. I recommend that you get one piece of Vog Cub and one piece of Skolver. This is enough for FSC. Then get Crest of Almire. Then, that armor setup could get you through SGWW, if you have a good team. But it might be pretty tough. One piece of Dread Skelly or Valkyrie or Fallen would help a lot. (It's a devious feature of this game, that boss reward items tend to help you with their own bosses --- but you have to beat the bosses without the reward items, to get the reward items.)

For a sidearm gun, really any elemental gun will work. I vote for Nova Driver or Storm Driver, because (A) they will serve you well if you ever switch to gunning, and (B) they are less popular with sworders. Argent Peacemaker is easy to use. Polaris is very effective only in certain situations.

I plan on getting DV to replace Vog Cap and Snarby Cap/Skelly Cap.

Divine Veil offers really good miscellaneous defense. It's for people who want one armor suit+helmet for all occasions. I use it on my secondary character, who has only one loadout. But if you're going to get multiple specialized armor sets, then I don't really recommend Divine Veil. My main character rarely, rarely wears his.

And Bopp, I do hope that I can get snarby eventually, but should I get it straight away? Or become 5*, get a good income from FSC, then get snarby?

Well, Shadow Gloaming Wildwoods is harder than FSC, so you should probably master FSC first. And SGWW really benefits from a shadow shield, which you can get very well from FSC. And even with five-star armor SGWW is pretty hard, so I don't recommend that you try it until you have full 5-star equipment. (Yes, people do Shadow Lairs with suboptimal equipment. They have fast computers, low network latency, and lots of skill and experience. Maybe this describes you; I don't know you.) So I definitely recommend doing a bunch of FSC before trying SGWW. Really, only do Shadow Lairs when you're finally bored with the rest of the game.

In case you're asking about buying Snarbolax from the Auction House: Don't. It's expensive, and it robs you of your feeling of accomplishment.

I was aiming for DV because I can use it with Vog, Dread/Snarby coat, or skolver

Oh, I didn't understand that you were trying to use a single helmet with various suits. The problem here is that DV doesn't have any normal protection. So it's (almost) impossible to work into a perfect loadout.

So so far you are telling me: Get Vog, then Skolver, then dread, then snarby?

You might be able to skip the Dread Skelly step; it depends on how good you and your team are.

Here is the cheap way to do things: Divine Veil, Skolver Coat, and Grey Owlite Shield or Barbarous Thorn Shield. This is all you need to do the entire game except for Shadow Lairs. Then farm FSC to increase your skill and money. Maybe get Crest of Almire. Then wear Divine Veil, Skolver Coat, and Crest of Almire or Barbarous Thorn Shield into SGWW, and get Snarbolax. Depending on how good you and your friends are, this is either "no problem!" or "wow, we had to spend a lot of CE reviving".

Eventually, as you play the game more and more (with swords), you will form entire outfits out of Skolver, Vog Cub, and Snarbolax. You'll have nearly perfect loadouts, and Divine will rarely be part of them. But that day is a long way off.

Based on what you just said, Argent Peacemaker is certainly the (elemental) gun for you.

Storm, you have no respect from the members of arsenal community right now due to your "elite gun guide."

And there's another way of doing puppy room in fsc, no gun required.
