Description

The Builder was an enemy that appeared in Narratorium as a part of The Final Act Event. It had the highest health out of all enemies that appeared so far, but it was only as fast as the Attendee. It has one ability where it throws a brick at a tower or unit, which upon impact splits into three additional bricks. Any tower hit by them was stunned for 2 seconds while units received 150 damage.

Logbook Description

"The Builder is a creature created specifically to help the Narrator construct his grand visions. It handles all construction work, from laying foundations to adding decoration. The builder is only animated by a soul which Righty and Lefty can steal from a living being."

Appearance

The Builder is a plushie with a yellow head, black legs and arms, and an orange torso. On its torso, it has a zipper while on its head it wears a yellow and blue hard hat. It has two black button eyes and a giant open mouth with a visible tongue.

Strategy

As this enemy only appears through Sandbox mode, no strategy section is made for its current version. Instead, a strategy section for the one that appeared without Sandbox mode in The Narratorium is listed instead.

• Early-game towers like the Crook Boss, Golden Soldier or Golden Crook Boss are pretty useful here.
  • The Toxic Gunner and Electroshocker can be used to kill multiple at once.
• Later on, the Builder becomes rather weak, meaning most towers should be capable of defeating them, including late-game towers like the Accelerator, Turret, Ranger or Pursuit.
