Quick answer: The Island 4 update introduces ores across two main locations: the Bamboo Cave (including the 10x multiplier Onyx) and the Holy Tree (featuring the Lucky Cat ore). Confirmed traits for the new materials currently focus on Swiftness (movement speed) and Vitality (health).

The Crimson Sakura Isles expansion for The Forge on Roblox adds a significant collection of new ores to mine, distributed between the Bamboo Cave and the area surrounding the Holy Tree. These materials are essential for crafting the latest tier of weapons and armor, with some offering passive traits that boost character stats when used in sufficient quantities.
Mining these resources requires accessing Island 4 and using a pickaxe capable of breaking the local geology, such as the Bamboo Pickaxe. Below is the complete breakdown of drop chances, multipliers, and known traits for the new ores.

Understanding Ore Traits
Some ores in the Crimson Sakura Isles possess passive traits that activate when forged into equipment. To achieve the maximum stat bonus listed (such as the full +10% Vitality from Earthite), the specific ore must typically make up at least 30% of the crafting recipe. Using a smaller percentage (down to 10%) may still trigger the trait but will result in reduced values.
Currently, the identified traits for Island 4 ores are focused on mobility and survivability:
- Swiftness: Increases movement speed. Found on Bamboo, Water Stone, and Rock Seed.
- Vitality: Increases maximum health. Found on Earthite.
As players experiment further with the Holy Tree ores, additional traits may be discovered for high-rarity items like the Lucky Cat or Heavenly Orb.
