PvE Analysis

Recommended moves

Poison Attacker:Poison Jab Sludge Bomb

Grimer's stats are too low for it to benefit from the Shadow boost in Raids. And Gym defense is anyway out of question, given the lowered DEF due to the Shadow nerf.

PvP Analysis

Recommended moves

Great League:Poison Jab Sludge Mud Bomb

🔵 Great League

Shadow Grimer has its issues. Not only is the lack of a second typing a disadvantage, Shadow Grimer can't even reliably beat Pokémon a Poison type is supposed to beat. Seeing all this from a level 50 Pokémon is tragic.

However, unlike the regular form, Shadow Grimer beats Gourgeist Super, Lickilicky, Talonflame, and Guzzlord. This doesn't mean that Shadow Grimer is meta-relevant, as it also loses to Feraligatr, Seaking (both beaten by the regular variant) and also loses to most of the Great League meta.

With a max CP of only 1553, Shadow Grimer isn't functional in the other PvP Leagues.

Catch probability with multiple throws

In order to help Trainers understand their overall odds when catching Shadow Grimer, we enable the functionality to showing the total chance to catch it depending on the number of available throws. We calculate this chance as if you repeated the same throw N-number of times.

To activate this functionality, change the number of Number of throws to a value greater than 1. The Number of throws option is available in the configuration options above the chart

Catch rate formula

Pokémon GO catch rate formula can be expressed as follows:

CATCH_MULTIPLIERS = ball * curve * berry * throwType * (type1Medal + type2Medal / 2)
CATCH_RATE = 1 - Math.pow(1 - baseCatchRate / (2 * cpm), CATCH_MULTIPLIERS)

There are different multipliers that come into play when calculating catch rate.

Curved throws are more effective than regular throws, stronger types of Poké Ball have a higher catch rate, and using a Razz Berry or a Golden Razz Berry also improves your chances.
