❓Why synthesize?
Hero NFTs in EXTOCIUM have "base stats." These "base stats" determine mining efficiency, combat efficiency, succession conditions, and more. When a hero is first summoned, their base stat is at the lowest grade of 15.
You can use Hero NFTs with the same base stats as materials to increase the stat grade by 1 step at a time. Check out how to do it on this page!
❓Go to synthesis
You can find the synthesis NPC by going to Rotten Hill > Magic Shop > Ashurbanipal Library.

👉Talk to 'Chavakiah', one of the four NPCs in the Ashurbanipal Library.

👉Tap the synthesis button.
❓How to synthesize

👉This is the screen where you can proceed with synthesis.
1️⃣ Select the NFT to be the "synthesis subject" in slot 1. 2️⃣ Select the NFT to be the "synthesis material" in slot 2.

👉 First, tap slot 1️⃣ to display a list of synthesizable NFTs. Tap the 'select' button to choose the "synthesis subject."

👉 Then, tap slot 2️⃣ to select the material NFT.
👉 If all the necessary gold for synthesis is prepared, tap the 'synthesize' button to proceed.

👉 Here is the synthesis result for hero #2184. The base stat has increased from 15 to 16.
