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 are unaffected by Primary Stats, such as % Damage, Life Steal, Attack Speed, Crit Chance. But is affected by Engineering & Range.

Turrets are affected by Secondary Stats such as piercing and bouncing granted by the items Bandana & Ricochet (with a 50% damage falloff). Explosive Turret benefits from Explosion Damage and Size granted by Dynamite & Plastic Explosive. Turrets can inflict burning with Scared Sausage, and Snake helps Incendiary Turret inflict burn to more targets.

Ugly Tooth lets your turrets slow enemies on hit. Boxing Glove adds knockback to your turrets. Which might not be something you want.

Landmines are affected by Engineering, Explosive Damage, and Explosive Size.

Having negative Engineering instead decreases damage and healing of these structures and weapons down to a minimum of 1.

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 fire rate of the turrets with the Improved Tools item which makes the turrets scale with 50% of your attack speed.

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.
