There are a number of Resources to be found in Eiyuden Chronicle: Rising. Some of these Resources are dropped from monsters. This page will detail the location of the Ancient Crystal resource.
- Occasionally found in the Runebarrows, these crystals are highly sought after, and thus highly valuable.
Each main dungeon area of the game has a specific resource associated with it that only drops in that specific dungeon. These resources are a rare drop from any enemy in that dungeon, which means you will have to keep killing enemies and hopefully get lucky to have it drop. The Ancient Crystal is one such resource, with it being a rare drop from any of the monsters inside of the Runebarrows. You will be visiting this often enough, that you should be able to get a few of these just running through the dungeon and killing monsters.
You’ll know the rare resource dropped whenever you see a blue sparkly coming out of a defeated enemy. At first, there isn’t really much you can do to increase the chances of getting the rare item to drop, other than just praying to the RNG gods. However, as you unlock the facilities, one of them will be the Accessories Shop, headed by Squash. He will allow you to craft accessories that do a number of things, such as increase your stats or let you get more resources. Of particular note, especially for the rare resources dropped from enemies, is the Rarity Pendant. As the name suggests, equipping this will allow you to increase the chance a rare item drops from an enemy.
Note that this only seems to count when it’s equipped to the character delivering the killing blow. Also, they do stack, so you can equip two Rarity Pendants, if you happen to find/craft them. You might also find one or two of these pendants inside of chests while exploring, so it’s a good idea to open all of the chests you find. Note that you cannot trade for these at the Trading Post normally, so you will have to solely rely on getting them from drops.
