As skill information leaked (prior to me joining the beta), I made what I thought was going to be an epic build as a sorcerer wearing medium armor and using a two-handed sword. I carefully balanced magicka and stamina usage, as well as balanced out the skills on my weapon swaps. I stuck to this build as long as I could, and eventually figured out that it was going nowhere. After seeking out the advice of others on how my class could beat boss Mannimarco (who has since been nerfed) I realized I had gone in such a direction that my character could be much, much better. After some tweaking, adopting as much advice into my build as I could, I was able to beat Mannimarco. While this seems to have nothing to do with the game economy or making gold, there is a lesson to this story. The lessen is that the wisdom of the experienced can prove to be invaluable. All you have to do is listen.
(This was my character a few hours after fighting Mannimarco and had time for a breather, and the time to take a selfie evidently)
Time is a precious thing. We here at Tamriel Gold Goblin have been saying for ages how time is money. Truth is, money is money. Time is just another currency that we take to the bank and exchange for money (gold). Saving time doesn't always mean saving money. First, you need to spend time learning and understanding before you get the best exchange rate of time for money (gold). Not everything can be read online, some things need to be experienced.
Between level 1 and level 10 I found I was mismatching gear because that is just what I was picking up. If you know what kind of gear you want (light, medium, heavy, or a combination), ask your guildmates and party members to keep an eye out. The same goes for weapons, and this advice isn't limited to levels 1 through 10. If you can get gear for free, perfect. If you can get gear without you or a friend paying a guild store fee, awesome. It's a win-win. Plus, come launch and pre-launch, how many guild stores will you even have access to? Not many.
"Vendor Trash" is typically considered common gear that isn't worth taking the time to sell to players. This is such a dirty word on new servers and for new characters. On the last character I created, I was still using level 4 gear on a level 10 character. Why? Because I hadn't come across anything better. Loot tables may not always be balanced, and nothing is guaranteed. Everyone needs better gear, even what others may consider to be trash. Find something you think is useless to your build? Post it in party and guild chat. If someone wants it, sell it to them for a bit more than the vendor would offer. They get gear, you get gold.
There are also a number of items you will NOT want to vendor. Some of the immediate ones I can think of are Racial Motif Books, Soul Gems, Green, Blue, Purple, and Yellow crafting materials, Blue, Purple, and Yellow Provisioning recipes, Racial Style crafting materials, and treasure maps. Each have their own value, even if its only that you'll end up buying them at some point. Racial Motif Books and their crafting materials are super important to anyone crafting weapons or armor. The books unlock styles, and the materials are used for that respective style. The rarer the style, the rarer the material. The colored crafting materials and recipes are also harder to come by, and are essential for top of the line gear. Soul Gems go like hotcakes in PvP. If you haven't heard, these are needed to resurrect yourself and others in both PvP and PvE. Most bosses in group dungeons prevent you from resurrecting yourself, so it would be nice if your group mates had a few to spare.
So, you think you know what craft you want to do (or have decided not to craft anything). Well, you're wrong. Even if you're already in a guild that has all the crafts covered by various players, you're going to want to gather materials for a craft you're not doing. Namely Alchemy and Provisioning materials. These are consumables that restore resources and temporarily enhance your character. While potions and food drop and can be bought from NPCs, the crafted quality is superior to any drop or vendor item. Some Alchemy and Provisioning materials are rarer than others, and all recipes call for specific ingredients. Anyone crafting these items will always have a shortage of certain ingredients. By picking these up from level 1, you will (eventually) find someone who wants to buy them, or find a crafter that can use them to make you something you want.
In terms of which armor to use, or to craft, there are a few things you should consider (or reconsider). Light armor is designed for magic users, medium designed for stealth, and heavy for tanks. Be sure of which you want to use. Making the crafting switch could cost you months of time in researching traits, and tons of gold in new crafting materials. If you aren't 100% sure (pretty much anyone who wasn't playing PTS in my opinion) then keep your crafts available by researching some of everything. Eventually you may want to respec your skill points towards a different craft. And so if you research some other gear, the time sink will be lessened. There is the trade off of wasting time and energy in performing the research. In my opinion though, it is worth it, even if you think you are 100% sure of what craft you want to focus on. In terms of using armor though, I recommend going all in on what you think is best. Switching what armor you use is a relatively painful process.
Prioritize your expenses. The main things you will need to save gold for are bag/inventory upgrades, and buying a horse. At some point you may also want to re-spec your character. These are the three big sinks of gold. Start saving your septims, and decide which you are saving for. If you have the Imperial Edition, you start with a basic horse. There are even better horses though, and you are allowed to have more than one. I myself would save that even better horse for late game. A budget would also help to manage things like wayshrine fees and vendor purchases. Setting a budget on things like these will help reduce your spending and help you save for those major purchases.
And finally, the most important tip I can give you for your first character: Loot Everything. Especially in the tutorial areas of Cold Harbour. Cold Harbour can leave your character fully equipped and enough gold to upgrade further as soon as you leave. You'll also learn which types of containers provide which kinds of loot, and begin to recognize them from a distance.
Now if you'll excuse me, I need to head over to the convenience store to stock up on supplies, attend a guild meeting, finish upgrading my computer, then take a nap before I hop on ESO tomorrow. I hope to see you all in game.
