Get Armorsmith lvl400 > lvl 500?
http://www.gw2crafts.net/armorcraft_400.html
The guide updates itself based on TP prices to ensure the cheapest leveling straight to 500, so make sure it’s refreshed right before you start and don’t refresh it again until you’re finished (or it will keep changing and be inconsistent). Meant to be used in one sitting.
1. refine until you get to 425.
2. discover exotics from anything you are not going to need later (cleric, valkyrie, knight, carrion) till you get to level 450. Whatever you create salvage with BLSK to get Dark matter orbs and ectos.
3. refine ectoplasms and obsidian as long as you are able to wait… this gives very little experience. OTOH you are going to need a lot of the obsidian / ecto stuff later, so if you are not lazy…
4. finally return to discovering (and salvaging) exotics.
Remember – you can get experience even from discovering lowbie stuff. When you are out of stuff and money, you can do the rest of the last level discovering even masterwork lvl 400 stuff, and the mats are very cheap and you will likely have a lots of these.
You can get ~10 lvls by discovering lv80 rares,greens and blues. That is pretty cheap.
