Drought: Ability Breakdown

Ability Effects
☀️

Sets Harsh Sunlight on entry (5 turns)

No Sun move required. Under Sun: Fire moves ×1.5, Water moves ×0.5, Chlorophyll / Solar Power / Protosynthesis abilities activate. Unlike Koraidon, Drought is a standard ability — 5-turn timer applies.

💥

Precipice Blades: 120 BP Ground Spread

Precipice Blades hits both opponents in doubles at 95% accuracy. With 150 base Attack, this is one of the most powerful spread moves in Regulation F — only the accuracy prevents it from being universally dominant.

🔥

Sun enables Fire-type teammates

Groudon’s own Fire Punch becomes devastating in Sun; Drought simultaneously powers Flutter Mane’s Fire coverage and any Solar-Power or Protosynthesis allies.

Team Building Partners

Flutter Mane
Sun Special Core

Solar Power under Drought boosts Flutter Mane’s Special Attack to an effective ~303 — combined with Focus Sash, this OHKOs most opponents. Groudon sets Sun, Flutter Mane executes.

Incineroar
Intimidate Support

Intimidate protects Groudon allowing it to stay in and continue using Precipice Blades. Fake Out creates a free Drought activation turn.

Amoonguss
Redirection + Spore

Rage Powder redirects attacks away from Groudon; Spore under Sun with Safety Goggles Incineroar supporting creates a disruption-heavy defensive shell around Groudon’s spread damage.

Tornadus
Speed Control

Groudon’s 90 base Speed is slow for the current format. Tailwind doubles it to 312 for 4 turns — outspeeding the entire unboosted field and enabling Groudon to move first.

How to Counter Groudon

Water Spread Moves (Kyogre Origin Pulse)

Groudon has a ×2 Water weakness. Kyogre Origin Pulse in Rain is almost guaranteed OHKO. The weather war is Groudon’s primary structural weakness — Kyogre teams are natural counters.

Grass-type Coverage

Rillaboom Wood Hammer and Grass Knot exploit Groudon’s ×2 Grass weakness. Grass-type coverage is commonly used in doubles specifically to counter Ground spread damage.

Weather Override

Kyogre or Politoed’s Drizzle overwrites Drought — switching weather removes Groudon’s Sun boost and enables Water moves to threaten it simultaneously.

Levitate and Ground Immunity

Levitate Pokémon and Electric Terrain immunity completely negate Precipice Blades. Positioning Ground-immune partners is the primary way to neutralize Groudon spread damage.
