Introduction

The term “rate-up” shows up often in social games with a chance-based gacha system, and Girls’ Frontline is no exception; in this game, a production rate-up refers to a period of time during which craft rates are noticeably increased, usually affecting a specific type of production or set of units.

Official GFL announcements often advertise the in-game rate-up events. At the time of writing, GFL EN’s next rate-up according to the Monthly Roadmap is just around the corner, with maintenance notes confirming that the event will run between Sep. 24th - Oct. 1st, 2019.

Exactly what rate goes up, anyway?

There are two types of production rate-up events: one that involves all four types of factory production (including heavy) on a rotating schedule, and one that is tied specifically to newly-released T-Dolls. 

For simplicity’s sake, this article will refer to them as general rate-up and targeted rate-up respectively.

General Rate-Up

Since GFL EN’s release, general rate-up has occurred roughly three times a year. The previous rate-up at the time of writing took place on the game’s 1st anniversary; the promotional image for the September Rate-Up is included below for reference:

September Rate-Up Schedule

General rate-up events run for 8 consecutive days, broken up into 48-hour focus periods that run in the following order: 

  • Day 1-2: Standard T-Doll Production Rate-Up

  • Day 3-4: Standard Equipment Production Rate-Up

  • Day 5-6: Heavy T-Doll Production Rate-Up

  • Day 7-8: Heavy Equipment Production Rate-Up

In other words, this will be the crafting schedule for the September 2019 rate up:

Event Day Rate-Up Types What to Craft
Sep. 24-Sep. 25 Standard T-Doll Production AR, SMG, RF, HG, MG
Sep. 26-Sep. 27 Standard Equipment Production Equipment
Sep. 28-Sep. 29 Heavy T-Doll Production SG
Sep. 30-Oct. 1 Heavy Equipment Production Fairies

During the event period, only the matching type of production will have increased rates. For example, only standard T-Doll production rates are increased during the first two days; Heavy T-Doll Production rates are not affected. Commanders who wish to craft SG T-Dolls should wait until the fifth/sixth day.

Targeted Rate-Up

When a new batch of T-Dolls is added to the game, a 2-day targeted rate-up (also known as banner rate-up) usually accompanies their release to help players “target” craft them. Here is the promotion image for EN’s most recent targeted rate-up at the time of writing:

rateuprecent

The Girls’ Frontline EN server typically holds targeted rate-up events on the weekend following maintenance, during which the pull rates of the newly-added T-Dolls are significantly increased. As maintenance typically occurs on Tuesday, this leaves a 4-5 day gap for players to save up resources and contracts.

Does Rate-Up actually work?

The short answer: yes.

Unlike certain other games that will go unnamed here, GFL rate-ups are significant and actually provide a very noticeable boost to high-rarity doll drops. 

Targeted rate-up events seem to have an undocumented mechanic wherein the first craft during rate-up is almost guaranteed to give a banner unit, added very recently to both EN and the foreign servers. Many players were pleasantly surprised to have crafted P90 or ADS on their first pull, only to find out that it happened to everyone else. 

While exact rate-up mechanics for non-guaranteed crafts have not been disclosed by the developers, the GFDB database provides a fairly comprehensive dataset for EN server production that can be analyzed to find out exactly how large the boost is. The following table is a summary of how rate-up affected the most popular recipes during the May 2019 anniversary general rate-up, which can be assumed to be similar to other general rate-ups:

5★ 1.6% 3.7% 2.3x
Note: Recipes are in Manpower-Ammunition-Ration-Parts. Rates for MG recipes only count the MG T-Dolls and ignore off-class drops.

As the data clearly shows, general standard T-Doll production rate-up is at least a 2x boost to crafting rates, with some recipes getting up to a 150% bonus. Commanders who saved their contracts and resources for this rate-up event will generally derive a lot of value out of it.

Standard Equipment Production

5★ Equipment crafting rates are also highly improved, by a similarly astounding ratio of 100-150% higher craft rates during rate-up. 

As there are so many recipes that it’s impossible to fit all the data into this guide, a table of recommended equipment production recipes will be included here instead. 

These recipes are far more effective than in-game recommended recipes, according to data from GFDB. The same recipes are optimal outside of rate-up, although at about half the listed 5★ rate. 

(“Scopes” includes VFL 6-24x56, EOT 518, ITI Mars in roughly equal proportions)

Recipe Total 5★ Rate Best For
210-80-150-80 15% Scopes, PEQ, Suppressor
270-40-270-190 13% Camouflage Cape
120-92-60-152 11% Exoskeleton, Armor
50-50-50-250 12% Ammo Box
240-240-40-130 9% Hollow Point Ammo
50-250-150-150 13% AP Ammo, HV Ammo, Buckshot, Slug

The 150-150-150-150 recipe for all random equipment also works, but is not recommended due to its high cost and the RNG nature of its crafting results.

What about Heavy Production?

Heavy Production is extremely expensive and unfortunately is barely improved by rate-up, with measured 5★ rate improvement falling anywhere between 0% to 25% depending on the recipe used. 

No, that 0% is not a typo - redditor /u/thatguyinthebox measured the effect of general rate-ups on Heavy Production with GFDB’s crafting statistics and found that they are barely affected compared to baseline values, with some recipes such as the standard 500x4 fairy craft not even showing any improvement at all!

The silver lining of this finding is that players don’t have to feel bad about spending all of their resources on standard T-Doll and standard Equipment production rate-ups; because heavy production is not improved much by rate-up, it is far more optimal to go for the standard rate-ups (in terms of pure resource efficiency) as long as there are still some desirable production results. 

Is there an in-game indicator for rate-up?

If for any reason you are not 100% sure which rate-up is in effect, the factory screen will work for confirmation in-game. A red “EVENT” badge will displayed next to either T-Doll Production or Equipment Production, depending on which rate-up is in effect. If there is no “EVENT” badge displayed, rate-up is not currently ongoing. 

rateupindicator

To know whether standard or heavy production is affected by rate-up, check the factory machinery icon to see if an upwards arrow is present in the standard or heavy production slots. The type affected by rate-up will have the arrow indicator. 

Should I start saving resources?

Generally, rate-ups are announced at least a week in advance. Players who still need a lot of things from production are advised to save as many contracts as possible, as well as enough resources to consume all contracts.

softcaps

Veteran players with a high softcap and plenty of contracts may instead opt to walk into rate-up with softcap resources, choosing to take advantage of the daily resource regeneration for maximized fairy crafts. 

Which Logistics missions should I run?

While a logistics chart/spreadsheet can give general guidelines on which missions are good, it is a disservice to include one and not mention the very nice community-maintained Logistics Calculator that can be accessed here

By inputting data relevant to your own unlocked chapters, resource needs, logistics cycle duration (how often you can check the game), and Great Success odds, this calculator can output the optimal set of logistics to run, fine-tuned specifically for your situation.

Should I craft T-Dolls or Equipment?

Low-rarity units with 5★ equipment will outperform high-rarity units with 4★ equipment, assuming similar skill types.

For newer players who have more than enough T-Dolls with decent skillsets to form some basic echelons of each type, crafting enough 5★ equipment to fully outfit two ARSMG teams, one RFHG team, and one MGSG team is a higher priority than crafting more T-Dolls. This means: 

  • 0 to 2 PEQ-16A (4★ PEQ is good enough)

  • 0 to 4 AC4 Suppressor (4★ Suppressor is good enough)

  • 4 to 8 VFL 6-24x56

  • 2 to 4 EOT 518

  • 1 to 2 ITI Mars

  • 1 to 2 Type 3 Armor Plate

  • 1 to 2 IOP X4 Exoskeleton

  • 4 to 5 IOP T4 Exoskeleton

  • 2 to 4 ILM Hollow Point Ammo

  • 0 SABOT Slug

  • 0 to 1 #000 Buckshot (5★ buckshot is not important but can be nice to have)

  • 2 to 4 Mk211 High-Explosive Armor-Piercing Ammo

  • 2 Thermoptic Camouflage Cape

  • 2 to 3 IOP Maximum Ammo Box

  • 4 to 6 APCR High-Velocity Ammo

Obtaining at least the bare minimum recommended number of equipment is a good idea before spending resources trying for rare T-Dolls that may not be immediately helpful. 

Should I craft SGs or Fairies?

In general, fairies offer a much higher return on investment than SGs. While some SGs do perform better than others, the difference is often not worth the massive investment needed to craft a specific 5★ SG.

Fairies, on the other hand, can be used in any echelon unlike SGs who have a very niche role. Having good, high rarity fairies can often unlock possibilities that are not otherwise available, while having good SGs typically only means a lowered repair bill every once in a while.
