🌀 Gigantamax Grimmsnarl Moveset
Grimmsnarl common fast moves are Bite or Sucker Punch or Low Kick. Charged moves include Dark Pulse or Play Rough or Foul Play and Power-Up Punch. G-Max Snooze not only delivers heavy damage but also leaves a damaging area for a short time — timing your swaps and using at least one bulky support reduces wipe risk.
Threat: Play Rough – heavy Fairy damage. Dark Pulse – solid Dark-type damage. Power-Up Punch – can boost Grimmsnarl’s attack
Pro tip: Dodge charged moves where possible, especially Play Rough, to keep your DPS high.
🌦️ Weather Boost
Gigantamax Grimmsnarl gets a weather boost in:
- Foggy weather (boosts Dark)
- Cloudy weather (boosts Fairy)
Your counters get boosted in:
- Snowy → Steel-types
- Cloudy → Fairy-types
- Cloudy → Poison-types
Battle Tips
- Lead with Steel Pokémon for maximum effectiveness.
- Avoid using Fighting or Dark Pokémon—they are resisted.
How the Battle Usually Plays Out?
Opening Phase
Start with your bulkiest Steel type pokemon. This allows your team to survive Grimmsnarl early pressure while building momentum.
Mid Battle
Grimmsnarl will start using stronger charged moves and Max Moves. This is where fragile Poison types may start fainting. Rotate into Steel types if needed to stabilize the fight.
Max Phase
When Dynamax or Gigantamax activates, use your strongest Steel or Poison Max Move. This phase deals massive damage and often removes a huge chunk of Grimmsnarl's HP.
End Phase
Maintain pressure, avoid unnecessary relobbies and keep your strongest attackers on the field until the boss go down.
Size
Recommended: 15–20 trainers for comfortable clears with mixed player levels. With many Gigantamax / Dynamax counters, 10–14 can work. Under 8 trainers should be attempted only if all participants are high-level and coordinated with ideal counters and Dynamax/G-Max boosts.
Rewards
Reasons include Pokédex entry, strong Dark / Fairy attacker, shiny chance, and XL Candy farming.
📌 Is Gigantamax Grimmsnarl Worth Raiding?
Gigantamax Grimmsnarl is mainly worth raiding for its unique Gigantamax form, Pokédex entry, and collection value. It is not a top-tier attacker, but it is a rare and interesting Pokémon to own.
Common Mistakes To Avoid
