Psychic-type weakness
Psychic-type defenders take ×1.6 from Bug, Ghost, Dark — those are the moves you bring when a Psychic raid boss or Psychic-type gym defender is in front of you. Below is the full chart of what hits Psychic hard, what resists Psychic, the inverse (where Psychic attacks shine and where they fall flat), dual-type matchups for the most common Psychic-pair defenders in the game, and the top 5 attackers per super-effective type pulled from the live tier list.
Single-type Psychic defenders take ×1.6 from any move of the listed weak-to types. Dual-type Psychic defenders stack multiplicatively — a second weakness from their partner type can push the multiplier all the way to ×2.56. Resisted attacks deal only ×0.625, and doubly resisted attacks (a stack of two ×0.625) drop damage to roughly ×0.39 — never bring those into a Psychic fight.
Use Psychic attackers when the boss in front of you is one of the listed types. Stack STAB (×1.2) on top by picking a Psychic-type mons that knows a Psychic fast and Psychic charged move. The combined multiplier is ×1.92 before weather.
Avoid Psychic attackers when the defender is one of the listed types. Resisted damage cuts your DPS by 37.5%; doubly-resisted damage cuts it by 61%. In raids this is the difference between a 3-account clear and a relobby.
Most Psychic-type bosses in the game are dual-type. Combined effectiveness multiplies through both types, so a Psychic/X defender may be ×2.56 weak to a single attacker type, or fully neutral if the partner type cancels the Psychic weakness. Pick the attacker type that maxes the multiplier.
| Dual-type | Examples | Top weakness | Mult |
|---|---|---|---|
| Psychic / Fairy | Gardevoir, Mr. Mime | Poison | ×1.60 |
| Psychic / Steel | Metagross, Solgaleo | Fire | ×1.60 |
| Psychic / Flying | Lugia, Latios, Latias | Electric | ×1.60 |
| Psychic / Fighting | Medicham, Gallade | Flying | ×1.60 |
| Psychic / Grass | Exeggutor, Celebi | Bug | ×2.56 |
| Psychic / Dark | Malamar | Bug | ×2.56 |
| Psychic / Ghost | Hoopa, Lunala | Ghost | ×2.56 |
Leagues: Great / Ultra / Master.
Mewtwo / Mega Mewtwo Y top raid attackers; Cresselia / Mew in Ultra ladder.
Knowing the Psychic weakness chart matters as much in PvP as in raids — a Psychic lead into one of the listed weak-to types loses the matchup before shields even come into play. Always check the dual-typing of the opposing lead: a single Psychic mons is harder to counter than a Psychic/Y where Y stacks a second weakness.
