Type Effectiveness does not generally affect Status attacks; only Physical and Special attacks are affected. For example, Confuse Ray, despite being Ghost-type, is able to confuse Normal-type creatures.
- A creature’s Types can render it immune to certain status categories, such as Fairy-types being immune to Charm. See Status Afflictions section for details.
Moves that deal set damage, such as Sonic Boom or Counter, are affected by Immunity but not by Resistance.
Depending on the Type of the attack and the target, there are 7 kinds of damage modifiers.
- An attack is Neutral if the target doesn’t interact with the type’s attack or if one type’s weakness is canceled out by the resistance of another type they have, dealing normal damage.
- An attack is Super-Effective if the target is weak to the attack’s type, dealing x1.5 as much damage. If both of a target’s types are weak to the attack, it is Doubly Super-Effective and deals x2 as much damage.
- Triply Super-Effective damage only happens through explicit interactions, such as taking falling damage at Speed Tier 3. This deals x3 as much damage and almost never happens from attacks.
- An attack is Not Very Effective if the target resists the attack’s type, dealing x0.5 as much damage. If both of a target’s types resist the attack, it is Doubly Ineffective, dealing x0.25 as much damage.
- An attack has No Effect if the target is immune to the attack’s type, dealing no damage and having no added effects.
Certain Moves can manipulate the effectiveness of specific attacks. For example, Foresight allows the creature’s Normal and Fighting-type attacks to neutrally damage Ghost-type creatures in addition to ignoring the target’s positive Evasion stat changes.
Some creatures (humans, specifically), do not have Types and take neutral damage from all sources unless stated otherwise.
Optional Rule: Inverse Battles – During an Inverse Battle, all combatants have their type effectiveness reversed. Types with Immunities instead take Neutral damage. Abilities and Moves that affect type-effectiveness remain the same; for example a Pokémon with Flash Fire will still Absorb Fire-type attacks.
- When do Inverse Battles happen? No idea. They are quite weird and probably a pain in the ass to actually play, but it’s a cool idea nevertheless.
