Guild Wars 2

What do you mean level 0 armor, if you’re talking about the starter armors from when you create a new character, it’s easier and slightly cheaper than upgrading your account like that (you can’t btw), just get a new character slot (or delete a character you don’t like) and go through all of the human character creation choices – it took me about an hour to get all the masks – there aren’t any full starter armors that can’t be found by salvaging/unlocking your loot. In fact I didn’t get any new skins aside from the starter headpieces and the engineer? backpack skin.

Maybe you mean the Krytan/Profane/Primeval sets that you get a choice of with the upgrade? They’re available for gems in the gem shop, I believe for less than the cost of an upgrade.

Do you mean the new set that comes with the revised Heroic/Deluxe edition?

The one tagged as “Suit of Legacy Armor”

You would have to buy GW2 again to get the armor and it only applies to one character (becomes soulbound, I think).

Edit: And to be clear, the “Suit of Legacy Armor” is a full set (head, chest, boots, gloves, shoulders, legs) but it’s only available for new purchases of Heroic/Deluxe editions.

There’s 6 armor slots:
chest
legs
boots
gloves
head
shoulders

When you start the game, you get chest, legs, boots. Then you choose something for either the head or shoulder slot. I don’t think there’s a class that gives you gloves at start. So your starter gear would consist of:
-chest
-leg
-boots
-head or shoulder

You can buy full set of lvl-0 armor from armor vendors when you have enough money. They sell all 3 grades – heavy, medium, light. As you level up, they change what they sell you every 5 lvls. So the next set of armor they sell will be lvl-5.

At lvl-0, they won’t be selling armor for head or shoulder slot. They start selling head armor at lvl-10. And shoulder armor at lvl-15. Other than your starting gear, there’s no way I know of to get lvl-0 armor for head or shoulder slots.

So at lvl-0, they will sell you:
chest
legs
boots
gloves

When you start the game, you can immediately start crafting. You will be able to choose 2 crafts at a time for free. To change a craft, you have to pay. But you can choose a craft that will allow you to craft full sets of armor starting at lvl-5 and continuing every 5 levels with few exceptions.

It’s the same for the head and shoulder though. You you can only craft head armor starting at lvl-10 and shoulder armor starting at lvl-15.

Each piece of armor also contains an upgrade slot for runes. You can also craft runes. However, the ingredients to craft a rune can usually sell on the BLT auction for far more than it would cost you to just buy one off of there.
