Elements

Every enemy, every module and every attack has a specific element. Elements can be strong or weak against certain other elements.

Strengths & Weaknesses

A list of the elements and their effectiveness against other elements can be found in the following table.

Defender→ Attacker↴	Neutral	Fire	Water	Earth	Air	Light	Darkness	Nature	Electricity	Universal
Neutral	100%	100%	100%	100%	100%	100%	100%	100%	100%	100%

Difficulty Factor

During Tower Testing, higher difficulty modes exaggerate the base strength or weakness by a certain factor. The formula for this interaction is:

(Eff / 100)^Fac × 100

Where:

• Eff is the base effectiveness, as a percentage, found in the table above.
• Fac is the difficulty factor, found in the table below.

For example, Fire enemies would usually take 25% damage from nature attacks. On impossible difficulty, this damage would be reduced to just (25 / 100)⁸ × 100 = ~0.0015% damage.

On the other hand, if using water attacks, the fire enemies on impossible difficulty would instead take (200 / 100)⁸ × 100 = 25,600% damage.

Difficulty	Factor
Easy	1
Medium	1.5
Hard	2
Insane	3
Nightmare	4
Impossible	8
