# Fusion ## Fusion logic The Legend Isla is where users can get high rarity NFT items by merging NFT items together. The fusion progression costs Elixir and MSTR. Fusion progression requires 4 **"Unlocked"** items with rarity from Uncommon to Epic: * **1 Main target item:** That will be upgraded to higher rarity rank item. Item type and race (if have) will be kept same as the Main target item. The Main target item require a certain level requirement: * **Mongens:** level 20+ * **Plots:** 50% max level (round up) * **3 Sacrifice items:** same item type and rarity level with the Main target. As a quick refresh, each Mongen consists of 6 different body parts, including Form, Head, Eyes, Horns, Tail and Back. The fused Mongen will be born based on gene of the Main Mongen and 3 Sacrifice Mongens. Each Mongen gene contains: * Main Trait: Body parts of Main-Mongen * Sacrifice Trait: Body parts of Sacrifice-Mongen * Up Trait: Higher rarity body parts of Mongen race The traits define the personality of each Mongen and these are randomly created. In other words, each trait has different probabilities of appearing in the next Breed. You can check table of the probabilities that have to appear the traits below:
