Engineering

Engineering

Engineering increases the Damage and healing of your Structures, such as Turrets and Landmines. Engineering also increases the attack damage of the Weapons Plank and Screwdriver.

Turrets and Landmines do not scale with Primary Primary Stats except Engineering, but do scale with Secondary Stats and other effects provided by Items.

See Structures for a comprehensive list.

Characters that have synergy with Engineering include:

• Cyborg - Gains a large amount of Engineering in the middle of the wave.
• Engineer - Gains addtional Engineering and turrets spawn in a cluster.
• Entrepreneur - Turrets ignores the -50% Damage modification penalty.
• Multitasker - Turrets ignore the -% Damage penalty.
• Old - The smaller map helps turrets be in range of enemies.
• Streamer - Gains 2 Armor per Structure.

Turrets Fire Rate

The base Fire rates of the different turrets are listed below.

You can increase the attack speed / Spawn rate of Structures by increasing your Structure Attack Speed. You can gain 10% Structure Attack Speed with the Clockwork Wasp, or you can convert 50% of your Attack Speed into Structure Attack Speed with the Improved Tools item

Turrets spawned by Wrench are the same as the turrets spawns by their respective items.

The attack speed of turrets is slightly randomised between each shot to between 70% and 130% of the attack speed. So the Attack Speeds shown here are just the averages.

Turret	Atk. Speed
Turret	0.73s
Incendiary Turret	0.28s
Medical Turret	2.2s
Laser Turret	0.87s
Explosive Turret	0.87s
Tyler	2.2s

Trivia

• In an earlier version of the game, Range would affect your turrets despite the Tooltip of Engineering Stating otherwise. This was fixed as bug in Patch 0.8.0.03
