What Is Type Effectiveness?

Type effectiveness is a system that determines how much damage is done by a move of a particular type on a Pokemon with a particular type. It operates like a complex game of Rock-Paper-Scissors, where the 18 types have Pokemon they're strong against and Pokemon they're weak against.

Knowing about these type match-ups and using this system effectively could be the key to your success in the different mystery dungeons, so please read on!

How Does Type Effectiveness Work?

Type Effectiveness comes into play whenever you or the enemy Pokemon uses an attacking move. The game considers the attacking move's type and the target's type combination to determine what kind of damage the move will do.

In most cases, the move will be normally effective and deal a normal amount of damage. However, based on the type match-up, the move can be super effective, not very effective, or ineffective.

Super Effective Moves

If Cyndaquil uses Ember, a Fire-type move, on a Bug-type Pokemon like Wurmple, the move will be super effective! This means that the move will deal 1.4x more damage than it normally would.

While it feels great to deal super effective damage, remember that enemy Pokemon can also deal this kind of damage, so be careful!

Not Very Effective Moves

If Sunkern uses Absorb, a Grass-type move, on a Fire-type Pokemon like Cyndaquil, the move will be not very effective. This means that the move will only deal 0.7x the damage it normally would.

Try not to catch yourself using not very effective moves!

Ineffective Moves

If Cubone uses Bone Club, a Ground-type move, on a Flying-type Pokemon like Pidgey, the move will be ineffective. This means that the move will only deal 0.5x damage, so try not to use ineffective moves if you can help it.

What Is STAB?

STAB is an acronym that stands for Same-Type Attack Bonus and is a powerful buff similar to super effective moves. This bonus applies when a Pokemon like Cyndaquil (a Fire-type) uses a move it shares a type with like Ember (a Fire-type move).

With STAB, the Pokemon will deal 1.5x damage on top of any modifiers that come with the type match-up! Try using STAB moves as much as possible!
