Astral Ore is a Legendary upgrade item in Manhwa Legends, the Roblox tower defense game from Blackcat Studios. You spend it to advance a unit’s attributes, pushing a hero’s stats higher than base leveling allows. Because it sits at the top of the item rarity ladder, it is not something you stockpile casually, and each use is a gamble rather than a guarantee.
Quick answer: Get Astral Ore from Challenges, code redemption, the Workshop (craft one with 5 Sunfire Ore), the Battlepass, or Gyoteng’s Shop for 2,000 Gold, then use it to advance a unit’s attribute with a 50 percent success chance per attempt.
Every way to get Astral Ore
Astral Ore comes from five separate paths. You can earn it through gameplay, buy it outright, or build it in the Workshop. The table below lays out each source and what it involves.
| Source | How it works |
|---|---|
| Challenges | Earned as a reward for completing challenge objectives. |
| Code redemption | Handed out through codes when they include it as a reward. |
| Crafting (Workshop) | Built from 5 Sunfire Ore. |
| Battlepass | Granted as a Battlepass reward. |
| Gyoteng’s Shop | Bought directly for 2,000 Gold. |
The Gyoteng’s Shop purchase is the most predictable option because it costs a flat 2,000 Gold with no randomness attached. Challenges and the Battlepass reward it on a schedule tied to your progress, while codes only supply it when an active code lists it.
Crafting Astral Ore in the Workshop
Crafting is the route to take when you have Sunfire Ore to spare but no Gold or rewards lined up. In the Workshop, one Astral Ore requires 5 Sunfire Ore.
| Craft | Cost |
|---|---|
| 1 Astral Ore | 5 Sunfire Ore |
The conversion also runs the other direction. You can turn Astral Ore back into Sunfire Ore, but that trade is a poor deal and is not worth doing. Keep your Astral Ore for its intended job rather than breaking it down.
Using Astral Ore to advance a unit’s attribute
The whole point of Astral Ore is advancing a unit’s attribute, which raises that hero’s power beyond ordinary upgrades. The catch is the outcome is not certain.
Each attempt to advance an attribute with Astral Ore has a 50 percent chance of success. That means half of your attempts, on average, will fail and consume the ore without advancing the attribute. Plan for the possibility of burning through several ores before an advancement lands, and hold a buffer rather than spending your last one on a single roll.
Note: Because the odds are a coin flip, prioritize your strongest and most-used units when you spend Astral Ore. Sinking a rare, hard-to-farm item into a bench unit rarely pays off.
How to know it worked
A successful use advances the unit’s attribute and consumes one Astral Ore. A failed roll still consumes the ore but leaves the attribute where it was, so the visible attribute value is the clearest signal of whether the attempt succeeded. If the value did not move after you spent an ore, the 50 percent roll failed and you will need to try again with another one.
Between the flat 2,000 Gold price at Gyoteng’s Shop, the 5 Sunfire Ore crafting recipe, and reward drops from Challenges, codes, and the Battlepass, you have steady ways to keep a small reserve on hand. Build that reserve first, then spend it on the units you actually field so a run of bad luck on the 50 percent roll does not leave you empty-handed.
