Hollow Adaptivity Assessment 6 Guide

Hollow Adaptivity Assessment 6
Placement * Removeable
  1. Place Rapid Bangboo (Devilboo) first at the elevated position near the exit.
  2. Ahriman will spawn and place Brave Bangboo (Paperboo) at the exit to stop it.
  3. Acquire Kind Bangboo (Exploreboo) to get more cost to obtain other units faster.
  4. Place Brave Bangboo (Excaliboo) in the middle, which is in front of the Paperboo.
  5. To keep your units alive, put Kind Bangboo (Miss Esme) at the center to heal all the nearby allies.
  6. Place Rapid Bangboo (Boollseye) below Miss Esme.
  7. Put Rapid Bangboo (Snap) in the center of the top row, followed by another Snap in the bottom row.
  8. Another thing to note is that you can remove the Exploreboo to have more Rapid Bangboo at the top row.

The biggest threat during this stage is the Flame Cantor, a dangerous enemy capable of dealing massive AoE damage to all deployed units.

Place Kind Bangboo (Miss Esme) at the center of the field so she can protect your units whenever the boss unleashes its skill.

Hollow Adaptivity Assessment 5 Guide

Hollow Adaptivity Assessment 5
Placement * Removeable
  1. Place Rapid Bangboo (Devilboo) at the elevated position near the exit to attack the Miasma tumor.
  2. Quickly put Brave Bangboo (Paperboo) at the exit after eliminating the miasma.
  3. A new enemy wave will spawn, so put a Brave Bangboo (Excaliboo) at the center near the exit.
  4. Place another Rapid Bangboo (Devilboo) beside the first Devilboo.
  5. Once you have enough cost, get Kind Bangboo (Miss Esme) for the top row to heal the nearby units, especially the Paperboo.
  6. You can add Kind Bangboo (Exploreboo) to the bottom row to gain more cost for upgrading or for acquiring Paperboo for the exits.
  7. Add another Rapid Bangboo (Snap) beside the Exploreboo to slow down the enemies before reaching the Paperboo.

The strategy of this stage is to always keep a Brave Bangboo (Paperboo) at the exit, so it can tank all the damage from the Dullahan while having the Rapid Bangboo units deal long-range attacks to it.

Hollow Adaptivity Assessment 4 Guide

Hollow Adaptivity Assessment 4
Placement * Removeable
  1. Place Kind Bangboo (Exploreboo) first at the top corner.
  2. Then place Rapid Bangboo (Devilboo) at the center.
  3. Get Brave Bangboo (Excaliboo), then place it on the left side and upgrade it immediately so it can target enemies before they get near.
  4. Place another Excaliboo on the opposite side, then upgrade it too.
  5. Add another Rapid Bangboo (Snap) near the entrance on the right side.
  6. Get Kind Bangboo (Miss Esme), then put her at the center to heal the surrounding allies.
  7. You can put another Snap on the left side and add another Brave Bangboo (Paperboo) on the other side.

Immediately upgrade both Excaliboos first before any other units. It will increase their range, allowing them to hit enemies from 2 tiles away. They can also hit enemies over the wall. Then, place Miss Esme to give you AoE healing and Snap to slow down enemies while giving additional damage.

Hollow Adaptivity Assessment 3 Guide

Hollow Adaptivity Assessment 3
Hollow Adaptivity Phase 1
Hollow Adaptivity Phase 2
Placement * Removeable
  1. The focus for the first wave is to remove all the Miasma Tumors in Phase 1
  2. Deploy Devilboo near the entrance where the first wave of enemies will come out.
  3. Then add Snap on the elevated platform near the exit.
  4. Put Boolseye next to the tumor near the third entrance.
  5. After that, put Exploreboo anywhere far from the entrance and upgrade it as soon as possible.
  6. Once all the Miasma Tumors are cleared, create a chokehold in the middle with Paperboo.
  7. After that, add Excaliboo and Avocaboo.
  8. The placement in Phase 2 retains the placement for Exploreboo and Snap. Then, needs to be used when the Arlaune obliterates the chokehold in the middle before.
  9. You need to create a new Chokehold with Excaliboo, Avocaboo, and Mercury to finish off the stage!

There are two phases for this stage due to the Arlaune that can obliterate an entire area. It's important to have the Avocaboo upgraded at all times to counter this as much as possible.

Hollow Adaptivity Assessment 2 Guide

Hollow Adaptivity Assessment 2
Placement * Removeable
  1. Place Devilboo and Boolseye near the Miasma Tumors to eliminate them as soon as possible.
  2. Place Excaliboo near the exit to make sure nothing actually gets in the exit.
  3. Put Exploreboo and upgrade it as soon as possible.
  4. Then place Mercury right in front of the exit.
  5. To make sure that the chokehold in the placement does not fail, place Avocaboo immediately in the elevated platform and upgrade it.
  6. For extra damage add Snap across Avocaboo.
  7. Then simply, upgrade all the remaining Brave Bangboo Types.

The only ones you need to keep an eye on are the Arlaune, so it doesn't explode too close to your bangboos. Other than that, the chokehold in the exit should work to neutralize the Dullahan.

Hollow Adaptivity Assessment 1 Guide

Hollow Adaptivity Assessment 1
Placement * Removeable
  1. Hold off on placing Exploreboo wait to place Mercury, Devilboo, and Excaliboo.
  2. After that, wait until you get 12 Cost or so to place Exploreboo and immediately upgrade it.
  3. Place Avocaboo at the back to sustain the three attackers.
  4. After a while, place Snap for more damage.
  5. Use Exploreboo to your advantage and upgrade all the bangboo.
  6. There are only six bangboos, so if you wish to add more, you can, but this should be enough to complete the stage.

The only big threat is the Arlaune due to their ability to explode upon being defeated, so make sure your Avocaboo at the back is fully upgraded!
