Drop Rate Disclosure
Under Article 33(2) of Korea's Game Industry Promotion Act and its Enforcement Decree, the types and probabilities of paid randomized items in Core Breaker are disclosed below. The grade probabilities are also shown in the game under Odds on the Gear tab.
1. Products covered
The only item with randomized contents is the Supply Crate (called a Supply Order in the game). Opening one crate gives one piece of gear. Four things are decided at random for each crate: its grade, level, slot, and bonus stat. The probabilities and rules for each are in sections 2 and 3 below.
The gear goes into your inventory (49 spaces). If the inventory overflows, the excess is returned automatically. Gear that is no better than what you have equipped is returned first, starting with the lowest effective level.
Supply Crates are not sold for cash. From version 0.1.38 they are not sold for bills (the paid currency) either. In earlier versions you can order them with bills in the in-game trading post or on the Gear tab. You exchange gold for crates in the in-game trading post or receive them as in-game rewards (tasks, attendance, mail, the Prize Cart, excavation, and so on). Because gold and the pickaxe durability used for excavation can be obtained or restored with bills, the crate rates are disclosed below.
Every crate uses the same probability table, however you got it.
2. Grade probabilities
There are six grades: D, C, B, A, S, and SS. D, C, B, and A are available from the start. S and SS appear only after they open under the conditions below. The share of any grade that is not open yet is added to the highest grade available at that time.
- Grade S is available from Supply Grade 10. Supply Grade rises with the XP you earn each time you open a Supply Crate and receive gear.
- Grade SS is available after you buy "SS Gear Unlock" in the Retrofit tab. "SS Gear Unlock" appears in the Retrofit tab from Supply Grade 14 and is bought with core shards.
- Before grade S opens, the S and SS shares (0.4% in total) are added to A, so A is 5.4%. D, C, and B are the same as in the table below.
The table below shows the rates once grade S is open. The rates that apply to your account right now are shown in the game under Odds.
| Grade | S open, before SS unlock | After SS unlock |
|---|---|---|
| D | 52.6% | 52.6% |
| C | 30% | 30% |
| B | 12% | 12% |
| A | 5% | 5% |
| S | 0.4% | 0.3% |
| SS | - | 0.1% |
Each column sums to 100%.
3. Level, slot, and bonus stat
Separately from the grade, the following three things are decided at random for each crate.
| Item | Rule |
|---|---|
| Level | With R as your Supply Grade when the crate is opened, one of R, R+1, R+2, R+3, or R+4 (20% each). If your Supply Grade is 0, R counts as 1. The level is decided independently of the grade. |
| Slot | One of the slots you have unlocked, out of 8 in total (equal probability). With all 8 unlocked, 12.5% each. |
| Bonus stat | Grade D gear has no bonus stat. Gear of grade C or higher gets one of the 8 bonus stat types with equal probability, excluding the one type that overlaps with that slot's main stat. Helmet and Necklace have no overlapping type, so they get one of 8 (12.5% each); the other six slots get one of 7 (about 14.3% each). |
Gear of the same grade can differ in level, slot, and bonus stat from crate to crate. Gear with the same slot, grade, level, and bonus stat type has the same stats, and nothing else is randomized. The value of a bonus stat is set by the grade.
Each order is an independent draw from the probability table. There is no guaranteed grade based on the number of orders.
4. What is not randomized
Products sold for cash (bill packs, paychecks, bonus envelopes, the welcome kit, the ad-free pass, breakthrough supplies) grant exactly what the purchase screen shows. Boxes found during excavation, card draws inside a run, and the Prize Cart are rewards that come up while you play or watch an ad; the boxes and draws themselves are not bought with bills. Note that pickaxe durability, which excavation uses, can be restored instantly or have its maximum raised with bills.
