In Project Slayers 2, Ore is the high-end currency. It lets you get resets and boosts, as well as spin packs, without using Robux. Think of farming it as a chest hunt rather than a mob grind. The quickest approach is to open the most rare chests you can each hour, with world bosses supplying the drops that keep the chests coming.
Quick answer: Defeat world bosses, then loot the World Events Chests they leave behind; every chest has a 5% chance to contain Ore. The Yeti Demon at The White Terror Lair gives three chests when defeated, making one fight your strongest source of rolls.
What Ore is and what it unlocks
Ore sits in your Inventory as a Mythic-rarity item, described as trade tender accepted at special counters when ordinary coins will not do. Do not confuse it with Refinement Ore, a common crafting material that shares the same chests. Only true Ore counts toward your shop budget.
To use Ore, bring up the menu shop and select its Ore tab. There you can get the same paid conveniences otherwise bought with Robux: Clan Spins, Art and Demon Spins, stat resets, and timed boosts. Start a boost just before farming so its duration is not spent travelling.
Spin packs scale in value the more you buy at once. Here is the current spin pricing:
| Spins | Ore cost |
|---|---|
| 1 Spin | 1 Ore |
| 15 Spins | 4 Ore |
| 25 Spins | 6 Ore |
| 50 Spins | 10 Ore |
| 100 Spins | 18 Ore |
| 250 Spins | 40 Ore |
Resets and boosts round out the tab. Reset Breathing, Reset Fighting Style, and Reset Evil Art each cost 7 Ore, Reset Skill Points is 10 Ore, and Reset Reputation is 4 Ore. On the boost side, 2x EXP (30m) and 2x Mastery (30m) run 14 Ore each, 2x Wen (15m) and 2x Souls (30m) cost 7 Ore, 2x Lock (15m) is 20 Ore, and 4x Luck (45m) is the most expensive at 60 Ore.
There is no pity system on spins. High-tier Supreme clans such as Kamado, Rengoku, and Soyama come down to luck no matter how many spins you bank, so treat spin packs as chances rather than a guaranteed path.
Ore drop rates by source
The Archives entry for Ore names all containers that can award it. Since each rare chest type has the same rate, choose the route that lets you open the greatest number of chests per hour.
| Source | Ore chance |
|---|---|
| World Events Chest | 5% |
| Ice Chest | 5% |
| Rare Chest | 5% |
| Ouwigahara Chest | 5% |
| Sealed Cache T1 / T2 / T3 | 5% |
| Common Chest | 2.5% |
| Lost Chest | 2.5% |
| Snow Chest | 2% |
| Fishing | Extremely low |
| Final Selection graduation | Guaranteed |
| Quest: Restock the Infirmary | Guaranteed (one-time) |
| Quest: Supply the Settlement | Guaranteed (one-time) |
Everything else in those chests is filler you will see constantly, including Coin Pouch, Metal Scraps, and Refinement Ore. The 5% chest types are the ones worth building a route around, since the guaranteed sources only pay out once.
World boss rotation around Bamboo Grove and Mistfall Harbor
For Ore farming, build your route around world bosses: defeating one always gives you a World Events Chest, and each chest has a 5% roll. Their respawns follow a steady day-and-night-cycle timer, so a settled route can provide another chest every few minutes. Bamboo Grove and Mistfall Harbor have bosses near enough to chain together without lengthy travel.
The White Terror Lair: three chests from the Yeti Demon
The best place to farm Ore is this lair: one boss yields three individual chests, so a single fight gives you three 5% attempts. That is about three times the odds you get by fighting three standard bosses spread across the map.
Filler stops between boss respawns
While boss timers reset, pick up rare caches that already sit along your route. They carry the same 5% chance as the boss chests, so they cost you almost no extra time.
- At raid camps, Grove Raiders guard a red, glowing chest. Defeat them to get to the container.
- Ice Chests appear in frozen areas and are worthwhile stops on your return from the Yeti Demon.
- Dungeon chests, which drop decent loot but pace out slower than a boss loop for Ore specifically.
Make room in your inventory before beginning a loop. A chest can add several stacks at once; if there is no space for Ore, you lose the chance to collect it.
Guaranteed Ore from Final Selection
Completing Final Selection once as a Slayer awards an Ore package directly, making it quicker than earning your first Ore through 5% rolls. For another Final Selection attempt, use a Race reset from the Ore shop to change your Slayer back into a human. Count the Ore you have saved as your entry cost, and repeat the loop only when the chest rewards exceed the reset price.
Confirming your Ore landed
Check your Inventory after every chest. Ore is shown as a stacked Mythic entry with a special-counters tooltip. The stack total is the dependable way to verify a successful roll, because the loot feed moves too quickly to read after a chest opens.
Next, look up Ore in the Archives and make sure it remains listed for the chest you are targeting. Should that chest’s table stop including Ore, switch to a source whose table still has it. The key is how many chests you open per hour, not your damage output: save a modest reserve, pick the reset or boost you intend to buy, and build up the 5% rolls while clearing content already on your route.
