Core Rates
Cores are nice to have, so maps that give lots of cores must be nice. It takes something like 2000-3000 cores to craft a 5★ Para, so there's always a use for them - PR could happen this decade, and maybe even Singularity+ if we're lucky.
General rates#
Here's a list of popular core-farming maps and their estimated core rates (average cores obtained per run):
| Map | Core Rate | Source |
|---|---|---|
| 4-3E | 0.22 | Limited personal data (17 cores/79 runs) |
| 0-2 | 0.4 | Common claim |
| 0.40 | Personal data (267 cores/672 runs) | |
| 10-4E | 0.88 | Personal data (826 cores/936 runs) |
| 0.83 | Link | |
| 11-5 | 0.38 | Personal data (554 cores/1469 runs) |
| 11-6 | 1.24 | Personal data (359 cores/290 runs) |
| 12-4E | 0.90 | Personal data (8484 cores/9465 runs) |
| 0.85 | Link | |
| 0.88±0.08 | Link | |
| 13-4 | 0.86 | 9Tailed's data (5645 runs) |
| 0.85 | Personal data (1488 cores/1757 runs) | |
| 0.86±0.03 | Link | |
| 0.85 | /u/elgatoroid's data (244 runs) | |
| 0.87 | Minhthao's data (3298 cores/3810 runs) | |
| 0.852 | Zeseling's data (6372 cores/7476 runs) | |
| 0.868 | Ervhie's data (2450 cores/2823 runs) | |
| 0.859 | RevenantXIII's data (5756 cores/6704 runs) |
8-1N obviously gives no cores, but may be nice if you only want XP and want it fast. Heliport-spawned enemies generally don't drop dolls so 8-2 (SF dragging) doesn't give anything significant.
10-4E and 12-4E are decent sources of their non-limited 5-star drop. Personally, my SR-3MP rate is ~0.6% and my MDR rate is ~1.0% per run.
Cores per run isn't the only metric you should use. XP is also valuable, and each run will have different costs/requirements/time per run. Notably, 11-6 has a good core rate per run but involves more fights, isn't draggable, and uses a less accessible setup.
Rescue#
Some people have collected data with a SL10 rescue fairy active:
| Map | Core Rate | Source |
|---|---|---|
| 10-4E | 1.17 (+~40%) | Link |
| 11-6 | 1.62 (+~30%) | /u/UnironicWeeaboo - 281 cores/173 runs |
| 12-4E | 1.16 (+~30%) | Link |
| 1.12±0.07 (+~25%) | Link | |
| 13-4 | 1.15±0.04 (+~35%) | Link | ~1.09 | Limited personal data (204 cores/187 runs) | ~1.14 (+~35%) | LRP's data (771 cores/677 runs) |
Events and other maps#
Some maps aren't part of your usual farming regimen, but it may still be interesting to know their stats. These tending to be time-limited makes it hard to collect good data and thus the numbers will be a bit rougher.
| Map | Limited rate/check | Limited rate/run | Core Rate | Source |
|---|---|---|---|---|
| Jashin-chan normal ∞ | 2.1% | 6.3% | 0.79 | Personal data (620 runs) |
| 1.8% | 0.79 | 9Tailed's data | ||
| 3.3% | 1.1 | Limited personal data (80 runs, SL5 Rescue) | ||
| Jashin-chan EX ∞ | 2.6% | - | Pyrastrasza's data | |
| 1.62% | 1.13 | Limited personal data (154 runs) | ||
| DR 3.1 Ghost Sisters ∞ (straight line/3 checks) | ~0.44% | ~1.3% | 0.36 | Limited personal data (225 runs) |
| DR 3.1 Ghost Sisters ∞ (full clear/6 checks) | ~0.8% | ~4.8% | 0.69 | Limited personal data (207 runs) |
| Photo Studio Mystery ∞ (Webley route) | ~1.1% | ~4.3% | ~0.86 | Limited personal data (94 runs) |
| Valhalla: Chicken Breast EX | 1.3% | 7.8% | 1.25 | Personal data (184 runs) |
| Valhalla: Last Rain in the World EX | 0.8% | 4% | ~0.84 | /u/WhistleOfDeath's data |
| MS: The Symbolic ∞ - EX (Ch3) | 2.2% | 6.7% | 0.82 | RevenantXIII's data (1283 runs) |
| MS: Gaze ∞ - EX (Ch4) | 1.8% | 7.0% | 1.2 | Personal data (228 runs) |
| Lycan Sanctuary: Afterwinds EX | 1.0% | 5.9% | 0.88 | SkyClear's data (~200 runs) |
| Lycan Sanctuary: Afterwinds EX (SL10 Rescue) | 1.0% | 6.3% | 1.10 | Personal data (127 runs) |
Autobattles & Crafting#
Compared to corpse dragging, autobattles are horrendously resource-inefficient. If your time is limited and you've already got a 5-star parachute or two, they can be nice as a lazy way to level up the remainder of your armory. For general information including XP and resource efficiency, this excellent spreadsheet should be all you need. For core data, here are my observations:
| Map | Cores/run | Cores/kWRSC | Cores/hour | Sample size |
|---|---|---|---|---|
| 0-4 | 0.50 | 0.10 | 0.13 | 60 runs |
| 7-1 | 0.51 | 0.47 | 0.47 | 690 runs |
| 7-4 | 0.84 | 0.39 | 0.37 | 102 runs |
| 11-5 | 1.18 | 0.39 | 0.49 | 203 runs |
| 13-6 | 0.32 | 0.15 | 0.45 | 193 runs |
| Wolf & Owl II EX (Isomer) | 0.19 | 0.07 | 0.08 | 84 runs |
where kWRSC is 1000 weighted resources (parts triple value). 7-1 is the most resource-efficient map for XP, and this seems to also hold for cores. Its only limitation is a level cap of 97, so you'll need to look elsewhere to level mod dolls.
For comparison, here's how a few typical crafting recipes stack up:
| Recipe | Type | 5* rate | 4* rate | 3* rate | Cores/craft | Cores/kWRSC |
|---|---|---|---|---|---|---|
| 91/400/400/30 | AR | 7.7% | 14.8% | 20.7% | 1.03 | 1.06 |
| 400/91/400/30 | RF | 4.9% | 15.0% | 21.6% | 0.91 | 0.93 |
| 400/400/91/30 | SMG | 4.3% | 17.1% | 22.3% | 0.95 | 0.97 |
| 800/800/100/400 | MG | 6.5% | 16.2% | 21.8% | 1.03 | 0.35 |
| 130/130/130/30 | HG | 3.5% | 9.5% | 21.2% | 0.67 | 1.40 |
| 30/30/30/30 | Minimum | 2.2% | 4.2% | 22.9% | 0.47 | 2.59 |
As long as you have the contracts, crafting anything that isn't a MG will be substantially more resource-efficient than even 7-1 autobattles. XP not included, though crafting gets more valuable if you have missing spots in your collection or can use rolled dolls for links.
Other notes#
Have your own rescued_doll.csv and some maps you've farmed more than me? Feel free to message me (alt: BigStupidJellyfish#6974) and I'll add it as long as the data's decent. Many thanks to those who have contributed or otherwise posted their data.
