- Neutral Damage: 1.0x Damage
- Not Very Effective: 0.5x Damage (0.25x on dual-type double resistances)

Dual-Type Calculation Examples
When a Pokémon has two typings, multiply both single-type modifiers:
- Bug/Steel (e.g., Scizor): Fire hits Bug for 2x and Steel for 2x = 4x Quad Weakness.
- Water/Ground (e.g., Swampert): Grass hits Water for 2x and Ground for 2x = 4x Quad Weakness; Electric deals 0x (immune due to Ground).
- Steel/Fairy (e.g., Tinkaton): Combines the defensive profile of Fairy and Steel to yield 9 total resistances and 2 immunities (Poison, Dragon).
