How do dual types work??

Question

What im asking is like when a pokemon is grass and fire and its opponent uses a water move super effective against the fire but not very effective on the grass what does it make ??? super effective plus normal??

Comments

I was wondering the same thing.

Answer 1

As Speedy said, but if you want details:
Without effect: x0
Not very effective: x0.5
Regulary effective: x1
Super effective: x2

So, Water attack on Fire/Grass should have NOT VERY - SUPER EFFECTIVITY (1x0.5x2=1) which is same as regular effectivity

How do you know if it's not very effective, regularly effective and super effective?

---

It's not very effective when the type resists it, and usually in games they show it's not very effective with a sound or indication after the move hits. When it's regularly effective, it means the Pokémon doesn't resist the move, and neither is hit super-effectively. Or, the Pokémon has two types, and one of those types are hit super-effectively by a type, but the other type of the Pokémon resists that type. A Pokemon is hit super-effectively when the move it is hit by gets 2x of the normal power.

Answer 2

No it makes neutral damage, like rock/ground adds the water and grass weakness to make 4x weakness. Posion and flying makes 4x fighting resistance so they cancel or strengthen weaknesses and resistances. also immunities stay immunities
