There are lots of resources to find and collect on your travels through Allraan in Eiyuden Chronicle: Hundred Heroes. These are needed to purchase or upgrade facilities for the Headquarters which becomes available during the main quest, Separate Ways. Orichalcum is needed if you wish to unlock the final upgrades for the headquarters, but it’s quite rare and can only be obtained via the Mission Guild or in the Chelonian Goliath, Vilashnu dungeon.
Orichalcum can be found in the Chelonian Goliath, Vilashnu Dungeon
Orichalcum Uses¶
If you want to acquire all of the upgrades for the headquarters, then you’ll need to find Orichalcum, which can be done by interacting with the resource nodes in the Chelonian Goliath, Vilashnu Dungeon. This dungeon will become available when you go to recruit Dijkstra after the events in Norristar. It’s quite tricky to navigate and the enemies pose quite the challenge, so be sure to check out our Dijkstra Recruitment Guide for tips.
Alternatively, you can acquire Orichalcum by sending your troops out on the Beast Busters! task via the Mission Guild, but you need to purchase the “mission task 3” upgrade to make this available. This will bring you back some Orichalcum every 30 minutes. You can increase the quantity of rewards per mission by placing someone with the “Increase Stone” skill in the leader spot, such as Durlan. If you want to maximize the rewards from the Mission Guild, then check out our Mission Guild Explained to learn about the hidden parameters. Once you’ve acquired enough Orichalcum, then you’ll be able to unlock the following upgrades:
| Facility | Use |
|---|---|
| War Troop Boost 1 | Increases the fighting ability of troops and unit captains. |
| Smithy: Weapon Level 2 | Allows you to increase your weapon’s maximum level. |
| Accessory Shop: Merch 2 | Adds more accessories to the store. |
