Commander, remember when you told IOP to help build a new battle drill site and help G&K undergo strenuous training every single day when it's done? Kalin has some very exciting news to tell you!
Eh? You don't remember that at all?
I-It's okay! I'm sure it'll be a piece of cake for you. Here's a letter I wrote to help you out; you can click on it for more information!
Note from Kalina, made by Ysas of GFLCorner. Theater System Introduction by GFC

In totally unrelated news, G&K is opening its first casino! We'll be betting on the Theater scouting results this time with exclusive guests including FuryTomic, Ceia, Kirahuang from GFLCorner, as well as Dusk and Kyazuki from!

The stakes are apparently so high that some of them ran away after hearing about it... I wonder what they could be. 

Well, no matter! More famous EN commanders will be joining us in the upcoming days for a 21-day journey through Theater, so stay tuned!

Thanks to Ysas for this cute AT4 animation!

How can I prepare for Theater?

As mentioned in the guide linked above, there will be bonus dolls you can field for additional stats.

Bonus T-Dolls grant a minimum of 5% bonus each, scaling up to 8% at level 100. The total bonus cannot exceed 24% (so 3x Lv. 100 bonus T-Dolls caps it out).

For the last Theater event in CN, the doll list was as follows: 

Basic 1-4 Springfield Thompson P7 Skorpion Tokarev
Basic 5-8 Type 97 Shotgun Type 95 Type 97 NZ75 9A-91
Intermediate 1-4 M99 Thunder 100 Shiki Ameli GSh-18
Intermediate 5-8 HK21 USAS-12 DSR-50 Ribeyrolles KSVK
Advanced 1-4 Type 79 Carcano M1891 SPAS-12 ADS Super Shorty
Advanced 5-8 K2 Suomi Kar98k NTW-20 QBU-88
Core 1-3 Type 97 Shotgun Type 95 Type 97 NZ75 9A-91
Core 4-6 HK21 USAS-12 DSR-50 Ribeyrolles KSVK
Core 7-8 Type 79 Carcano M1891 SPAS-12 ADS Super Shorty

Note that this list is not necessarily going to reflect EN's bonus doll list for Theatre #1 (especially since KSVK is not out on EN yet); besides this list, players are recommended to level any non-duplicate dolls they have in their armory that they may find useful in the future.

I have the dolls, what kind of teams do I need?

The teams you need are pretty straightforward for everything except Core 8; for more information, check out the Theater Team Building Guide by Yuko!


Can I get AT4 to ★★★★★ if I place high enough?

In a single run of Theater, there isn't enough Central Data to max out its reward HOC. (Top 5% gets you 4★)

The fastest possible pace at which players can earn enough points to 5★ AT4 is by placing Top 15% in two separate runs of Theater. 

So Theater isn't a one-time thing? How often does it happen?

Theater is a relatively new feature even in CN. It's expected to happen 3-4 times per year, though EN's schedule may change. 

Do I need 5-star HOCs to do Core 8?

Not at all! You can clear Core 8 even with 2★ HOCs if you bring the right team

Do I need to CE stack to do well? 

You don't! The point difference from CE stacking is negligible compared to factors outside of your control like Scouting multipliers. (Make sure you bring as many bonus units as you can though!)

Top 100 is at the mercy of guessing correctly and percentile cutoffs depend more on your ability to do the daily checklist (seen in Kalina's letter above) than anything else. If you can clear Core 8 consistently then top 15% is pretty much guaranteed, if not top 5%.

What are some essential fairies for Theater?

  • Taunt Fairy is extremely good, perhaps even mandatory (at relatively high Skill Level, 8-10; SL10 highly recommended). 
  • Because you cannot use duplicates, Twin Fairy can be a good fallback if you need to give an HP sponge to multiple teams. 
  • Combat Fairies with meaningful skills (Airstrike, Warrior, Anna, etc.) will usually be more useful than strategy fairies, with the exception of strong stat sticks.
