Quick facts
Overview
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.

Moves & Threats
Rillaboom common fast moves are Razor Leaf or Scratch. Charged moves include Earth Power or Grass Knot and Energy Ball.G-Max Drum Solo 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.
Weather Effects
Sunny weather boosts Grass and Fire damage. Snow weather boosts Ice attackers.
Battle flow tip: Bring strong Fire and Flying attackers, especially if Sunny or Windy weather is active, for the fastest clears. Use top Fire and Flying attackers for maximum efficiency. Ice Pokémon can also help, particularly in Snowy weather conditions.
Battle Tips
- Bring a mix of high DPS (Fire/Bug/Flying/Ice) and at least one tank for large lobbies.
- Lead with your strongest DPS to shrink the boss fast — G-Max bosses have huge HP pools, so early damage matters.
- Quick-dodge only very heavy G-Max hits; too much dodging reduces total DPS in long fights.
- Star and favorite raid teams before joining to minimize relobby time.
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).
- Use Golden Razz for high-IV or shiny attempts, Pinap when farming candy en masse.
- Weather-boosted catches (Sunny, etc.) yield higher CP; plan catch attempts accordingly.
Raid Strategy & Catch Tips
Keep shields for heavy Grass charged moves like Solar Beam. Rotate attackers if your Fire or Flying types faint quickly. Golden Razz Berries give the highest catch success, while Silver Pinaps help farm Rillaboom Candy.
