Rillaboom

Rillaboom has a lot of raw potential, and could very well end up the apex of the Grass Type starters down the road. It has high raw power, and really only lacks access to Frenzy Plant to make its mark. It's not quite up to par with the royalty of the type, but it's still great.

Max Battles

Best PvE Offensive Moveset

• Razor Leaf pairs with Grass Knot for the best Grass Type damage that Rillaboom can muster until it gains access to Frenzy Plant.
• Scratch, Energy Ball, and Earth Power all fall behind in traditional DPS sense. However, as Scratch is a 0.5s move, it is useful in higher tier Max Battles to charge the Max Meter more quickly. Keep in mind that it will result in Max Strike instead of Max Overgrowth during the Dynamax phase.

Best PvE Defensive Moveset

• Razor Leaf sports good Defensive performance, while Earth Power grants counter-coverage against most Fire Types.
• Scratch, Grass Knot, and Energy Ball all fall behind.

Razor Leaf is primarily damage-oriented and has low energy gains, but it's superior to the competition. Grass Knot provides the lowest cost move at Rillaboom's disposal, while Earth Power provides reasonable coverage.
