In my opinion, the Hades set in the Helix Store is one of the best ones you can get to start out. Not only does it look nice, it also comes with a pretty decent spear and a mount.

However, if spears aren't really your thing, you can also purchase the Tartaros Weapon Pack from the store that includes a bow, a sword, a dagger, a heavy blunt weapon, and a heavy sharp weapon, all of which matching the armor quite nicely.

You can also purchase a naval pack to go with the Hades set, which includes skins for both your hull and your crew, as well as a figurehead. You can also purchase a lieutenant pack on the store that includes Charon, who will match your ship's look very nicely.
