The latest Subterra codes grant various important resources, boosts, and items. If you have just begun your mining adventure, the codes can help you level up quickly as well as unlock abilities and upgrades. The two main resources in this experience inspired by Minecraft and Terraria are Gold and Chrono Shards. Although several quests offer these as rewards, a more instant and time-efficient way of obtaining them is to use codes.

  • Approach the NPC named Chrysos and stay on the highlighted light blue area.
  • When the code box opens, copy an active code from this guide and paste it into the "Enter Code" text box.

Roblox Subterra promo codes provide several useful resources, items, and boosts. Among the free rewards is Gold, which you can use to upgrade your Pickaxe by speaking to the blacksmith, and increase your inventory space by interacting with Emilia. Also, the resource can be used to purchase items from the "Buy" area.

Another important resource in Subterra is Chrono Shards. With the crystals, you can buy Abilities after utilizing the Card Summoning system. If you are struggling to access the feature, follow these steps:

  • From the spawn area, head left and follow the pathway.
  • Once your progress is blocked by a building, head right to find a large, revolving crystal.
  • If you stand close to the crystal, a drop-down menu will appear with the options "Draw Cards" and "Manage Deck."
  • Choose "Draw Cards." Each Summon costs 140 Shards, and you choose one of the three cards on the screen.

Both Gold and Chrono Shards can be obtained by finishing daily quests, looting chests, and completing achievements. On the other hand, Keys are rare items that unlock chests.

Given that Roblox promo codes for Subterra are case-sensitive, you should ideally copy-paste them into the redemption box. Typos and incorrect letter casing when manually inputting them will result in an error. Moreover, remember that each code can be claimed once in an account. The notification "Already redeemed" appears during a case of double-redemption.
