Yamask (#562) is a Ghost-type Pokémon from the Unova region (Generation 5) in Pokémon GO. With a maximum CP of 1,123 at Level 50 with perfect 15/15/15 IVs, Yamask has its niche uses in certain battle scenarios. This complete guide covers the best moveset, PvP analysis, raid counters, evolution, and shiny availability for Yamask in 2026.
Yamask's Attack stat is 95 (Below Average). The lower Attack stat means Yamask may compensate with bulk or utility.
With 141 Defense (Good) and 116 Stamina (Average), the total stat product is 352. Trainers should be mindful of Yamask's limited bulk. Compared to other Ghost-type Pokémon, Yamask's stat distribution favors defense.
The best moveset for Yamask depends on whether you use it for raids, gyms, or PvP. For raids, use Astonish (Fast) with Shadow Ball (Charged) for maximum DPS. This takes advantage of STAB (Same Type Attack Bonus) which provides a 20% damage boost for matching-type moves.
For PvP (GO Battle League), energy generation and coverage matter more than raw DPS. Yamask has 2 Fast Attacks and 3 Charged Attacks to choose from.
In Great League, Yamask can be a viable pick. For Great League, lower Attack IVs (like 0/15/15) are preferred to maximize stat product under 1500 CP. The Ghost typing provides useful matchups against Normal, Fighting, Poison-type threats while being weak to Ghost, Dark types.
In Master League, Yamask faces tough competition from Pokémon with higher CP caps. It is better suited for capped leagues.
As a raid attacker, Yamask's effectiveness depends on its typing and 95 Attack stat. It may not be the top raid choice but contributes in the right conditions. Best counters against Yamask use Ghost, Dark-type moves.
Yamask can be found in the wild, hatched from Eggs, obtained through Research tasks, and during events. In Foggy weather, it receives a spawn boost. The buddy distance is 3km per candy — use Pinap Berries for double candy when catching.
Yamask is part of a 2-stage evolution family:
Tip: For PvP, check IV spreads before evolving (low Attack, high Defense/Stamina). For raids, aim for 15/15/15 perfect IVs.

Yamask gets a weather boost in Foggy weather, increasing wild spawn CP (up to Level 35) and raid catch CP to Level 25 (646 - 701 CP). The buddy distance is 3km per candy. Use Poffins to halve the distance.
