Niffelheim

This should be one of the last trophies you earn. As you adventure along, make sure you don't sell anything until all of your constructions, weapons and armor are all fully upgraded. You also want to make sure you have a handful of your favorite potions crafted so you don’t accidentally sell anything you need for those. It's even better if you wait until you have reopened the Portal to Asgard before working on this trophy as the Bosses drop some top quality items that sell for a pretty penny in the shop. Trading in all the items before you awaken the Dragon will guarantee you have the 1,000 Gold required to actually awaken the Dragon.

Once you’ve basically finished the main part of the game, start lugging all of the materials and items you've collected to Temple City to trade them in the shop. You are limited to how many items you can sell at one time! Once the store’s inventory is full, you'll need to wait until it resets before you can sell anything else (it takes about 4-5 in-game days before it resets). Due to this, you want to make sure you sell the higher quality items first, then make your way down to the materials that give you the least amount of gold in exchange for them.

As long as you’ve saved everything you can, you should come pretty close to 10,000 Gold after a few trips to the shop. If you've sold everything you can and are still short, you can do one of two things:

• Go down into the Mines and collect valuable order and stones
• Kill the Dungeon/Cave Bosses

The Boss method is the recommended of the two as the scrolls they drop are worth far more than the ore you'll find down in the caves.

Once you've traded 10,000 gold worth of items to the shop, the trophy will unlock.
