Weakness Best Pokemon Best Gigantamax Counters Dynamax & Support Picks Moveset Weather Effects Size Rewards FAQsOverview
Rillaboom’s Gigantamax form magnifies its Grass potency — expect powerful G-Max Drum turns that hit multiple times or apply amplified status-like effects (in concept). As a Grass-type boss, Rillaboom threatens with strong Grass STABs (e.g., Drum Beating analogues), possible Ground or Fighting coverage in special raids, and sustained physical/special damage. In both GO and SWSH contexts you should prioritize Fire, Flying and Ice counters, but also plan for hybrid coverage by checking the charged move preview before locking in.
Pro tip: Rillaboom’s access to coverage moves (like Low Sweep / Superpower / Drum Beating) can punish Pokémon that are poor against Fighting coverage — keep one flexible slot in your party.

Battle Tips
- Lead with Fire or Flying Pokémon for maximum effectiveness.
- Avoid Grass and Water Pokémon—they take heavy damage.
- eam coordination and dodging charged moves speed up the takedown.
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 Grass attacker, shiny chance, and XL Candy farming.
Rewards & Catch Tips
- Rewards typically include Rare Candy, Dynamax resources, and a chance to catch Rillaboom (shiny availability depends on event).
