How to unlock the Heart of a Dragon achievement in Remnant: From the Ashes - Definitive Guide
--->Apparently making a new character wont fix this so if you have already started the game you are screwed and this is still UNOBTAINABLE however if you are new and have just started you should be able to get it
8/30/2019 EDIT: It seems that they have fixed this achievement and the scrap achievements for the most part but seems others are still having issues, Mine as well as others got it to pop just by signing into out players.
To get this achievement you need to acquire an item called a simulacrum that are randomly across your world on the floor as all worlds are randomly generated. However in your first play through you should find around 3 or 4 of them if your looking around good enough.
You also need 10 lumenite crystals which are obtained by killing any big enemy who has a bigger health bar, they should drop pretty often but not always.
Once you have 1 simulacrum and 10 lumenite crystals, return to ward 13. You need to give the materials too the tree lady you must save in the campaign who will now look like a hunchback she is located in the same room south of reggie the guy who gave you the dragon heart. now just talk to her a few times and she will upgrade your dragon heart.
- 10 Lumenite Crystal, which can be obtained from special enemies, which you can identify by them being larger than normal
- 1 Simulacrum. This is harder to find, as they only occur once per world and can be hard to spot. If you do not spot any on a different world (unknown if they occur on Earth, most likely not), you can re roll the campaign to get another chance to spawn one, although this is ill advised and you would have to go through the game until you reach another world. They are similar looking to Lumenite Crystals, except larger and are yellow with a blue glow.
The Dragon Heart is this games main healing item and you will start off with three of them once you are given them early on in the game by Reggie. To upgrade you will first need to find 'The Root Mother' who is an NPC that you find during the story on Earth and is a mandatory NPC that you cannot miss. Once she is found she will go to Ward 13 and become a merchant that allows you to upgrade your Dragon Heart.
To upgrade the Dragon Heart you will need to find a 'Simulacrum', which is a very rare upgrade material, used for upgrading your Dragon Heart as well as the final upgrade for weapons and armor. There are said to be only one of these upgrade materials in each world, with 4 worlds that means there are only 4 per playthrough. Once you find one of these, return it to The Root Mother and along with 10 Lumenite Crystals pay her to upgrade your Dragon Heart.
Each upgrade will give you +1 to the amount of uses you have with the Dragon Heart up to a maximum of 10. However I would recommend not using your Simulacrums immediately for this purpose as you will need one for the "Push It to the Limit" achievement.
