Band of Brave Bangboo Event Calendar for Zenless Zone Zero
What is the Band of Brave Bangboo Event About?
The Bangboo combat evaluations in partnership with the military are not really meeting expectations, and they need the help of an experienced Proxy! You have to coach Aster's rescue and help the Bangboo pass their tests.
How do you Participate in Band of Brave Bangboo?
In order to participate you will need to reach Inter-Knot level 15 and complete Agent Story Mole in the Hole.
This event is similar to a previous one! Your goal is to pick and place your Bangboo in order to keep enemies from reaching the goal. However, this time you get even more Bangboo to choose from, with new powers, buffs, and more!
The assessments will also be much more challenging and complex than before. Expect new maps, enemies, ambushes, miasma, and more!
In order to start the event you need to head to Scott's Outpost and talk to coach Asher
It turns out that Seed has been training the Bangboo, but it is not really going as planned, and she is missing a few important steps! It is up to the Proxy to take over and teach the Bangboo how to fight!
Once the discussion over, you get access to the Event menu! On there you can find:
- Student Info: Lists the combat Bangboo you currently own, they stats and skills
- Assessment Level: Showcases your current level, and the next bonuses you can get from leveling up. The more you complete Bangboo Battles, the more you will increase your assessment level and unlock new perks
- Go to Battle: This is where you can start your next Battle
There are 4 days in total, and each day unlocks a total of 6 Battles. During the exams, Ethereals will appear one by one and attempt to break into the base. Your role is to pick up the Bangboo and place them on the field to stop the Ethereals from reaching the base.
The enemies will enter from one side, and progress to the other side. You want to place your Bangboo in between in order to stop them. If enemies make it past the base, it will loose durability. if your base reaches zero, you fail. Once all enemies are dead, the assessment is completed.
In order to place Bangboo on the field you can simply drag and drop them. They auto-attack enemies once in place.
You need a certain amount of assessment points in order to deploy your Bangboo. If you place multiple Bangboo of the same type, the assessment point cost will get gradually higher each time.
If it goes too fast, you can pause or slow down to arrange your lineup.
Most Bangboo can either be place on high grounds, or directly on the ground to block the way. However, one Bangboo can only block two enemies max, and they will take damage when placed on the ground.
You can also level up your Bangboo during battle with Assessment Points. Simply select the Bangboo on the field, and pick upgrade. This will help them deal more damage, or gain various bonuses.
Band of Brave Bangboo Solution
Anti-Infiltration Assessment 01
The first few stages are rather simple. You can start with any Bangboo, but 
Snap is
a good starting choice. As soon as possible place 
Plugboo. You can place a third one
if you want, but 2 are plenty enough for this one.
Anti-Infiltration Assessment 02
During this stage, some Ethereals hide in Illusory Bushes. You have to place 
Mercury strategically as
he is the only one who can intercept those.
Star with Mercury on the ground, and Snap on top.
once you can, add Plugboo at the top, and another Mercury in the Bushes
to help out. You can complete with another Snap or Plugboo
in the middle once it is possible.
Anti-Infiltration Assessment 03
Place Mercury in the bushes first, and an 
Exploreboo right on top of it.
The Exploreboo will most likely die after a while, just replace it. In third
position, place Snap all the way down. he immobilizes, so he is really good
against those fast enemies. After that, place Snap and Plugboo
where needed to help out.
Anti-Infiltration Assessment 04
This stage can be a bit more tricky, as the flying enemies pass bye Mercury.
Start with placing a Mercury and 
Avocaboo to support it.
Then we recommend placing Snap all the way to the left near the entrance, with an
Exploreboo. You will want to place another Mercury to
catch any enemy that would pass by the first one. After that, place Plugboo to
help out Snap. The first Mercury you place might die, replace it
directly with a new one.
Anti-Infiltration Assessment 05
Pick your first buff: Pre-emptive Tactical Chip.
place Mercury top right first with an Exploreboo and
Avocaboo for support. Secure the exit with Snap and
Plugboo. Place another Mercury in the middle left
to block the progression on this side.
Anti-Infiltration Assessment 06
Pick your buff: Pre-emptive Tactical Chip. If you struggle with Assessment Points, you can pick the Cost Reduction one instead.
The first enemies are those flying once that bypass Mercury, so
start by placing a Snap instead. After that, place Mercury
and Avocaboo near the enemy entrance. Add a Mercury on top in the middle,
and some Plugboo (or Snap) near the exit. Once the Big enemy
arrives, you will want to keep an eye on your Mercury and replace them when they die.
Territory Control Assessment 01
Pick your buff: Cost Reduction & Efficiency Resource Chip.
Make sure you do not block enemies on charger tiles, otherwise they get an ATK boost.
Place Mercury on top first, and a second one as soon as possible on the first charger tile down.
Next add Snap down to help out killing enemies, and Avocaboo to
support Mercury. Add another Snap or Plugboo at the top.
Territory Control Assessment 02
Pick your buff: Cost Reduction & Efficiency Resource Chip.
Place down Mercury and Avocaboo at the top first,
before securing the passage down with another one. Add Snap and Plugboo
on top to help out as a lot of enemies will enter from there towards the end.
Territory Control Assessment 03
Pick your buff: Charge Suppression Tactical Chip. It will the Bangboo who are placed on the charger.
Block the passage on top first with Mercury and add an Exploreboo
down left in order to swap the charger tiles and heal Mercury. Add Snap next to Mercury
on top, and right after block the passage down with another Mercury.
Add a Plugboo on top and one down. You might have to replace your Mercury
on top at some point.
Territory Control Assessment 04
Pick your buff: Charge Suppression Tactical Chip.
Place 
Excaliboo first on top. After that put Snap on the first tile down, in order to swap the
charger and heal Excaliboo. As soon as you can, upgrade the Excaliboo so it attacks
all enemies in range. Add Mercury right in front of Excaliboo. Snap easily holds the ground alone down,
so just take care of the top line and replace the Bangboo as needed.
Territory Control Assessment 05
Pick your buff: Charge Suppression Tactical Chip and Cost Reduction & Efficiency Resource Chip.
Place Excaliboo down, and 
Devilboo right next to it.

Avocaboo on the middle, and swap between Mercury and Excaliboo
in order to stop the big guy.
Hollow Adaptivity Assessment 01
Pick your buff: War-Sustaining Charge Chip and Cost Reduction & Efficiency Resource Chip.
You will have to watch out for Miasma. You can not deploy your Bangboo in there. Enemies get an ATK boost when standing in Miasma, so make sure to not block them right on it.
Place down Excaliboo on the right path first, right before the Miasma,
and Mercury on the path left, after the Miasma (but make sure enemies will not
stop ON the miasma, so put it down a couple of tiles after). Add Devilboo in the middle,
and Avocaboo to provide some support. Finish with Snap and
Plugboo for more DPS, and upgrade Mercury and Excaliboo
as soon as possible.

Avocaboo if needed on the left.
