Weak
The defending type takes increased damage from the attacking type.
Four outcomes to record
Resistant
The defending type reduces the incoming damage before dual-type multiplication.
Immune or neutral
An immunity can override the hit; neutral results often come from one weakness and one resistance.
Why this matters for guides
A guide that only lists weaknesses can miss key defensive context. Resistances and immunities are often the reason a counter is safe, not just the reason it deals damage. For species-level checks, connect the note to pages like Charizard-style dual types or Blastoise-style chart checks.
