Detailed Mechanical Explanation

For Discord/reference use

Core Mechanics

Compound Eyes increases the accuracy of all moves used by the Pokémon with this ability by 30% (multiplies accuracy by 1.3). This is implemented in abilities.cc:

constexpr Ability CompoundEyes = {
    .onAccuracy = +[](ON_ACCURACY) -> AccuracyPriority {
        *accuracy *= 1.3;
        return ACCURACY_MULTIPLICATIVE;
    },
};

Battle Effects

The 30% accuracy boost makes inaccurate but powerful moves much more viable:

• Sleep Powder: 75% → 97.5% accuracy
• Hurricane: 70% → 91% accuracy
• Stone Edge: 80% → 104% accuracy (capped at 100%)
• Blizzard: 70% → 91% accuracy
• Thunder: 70% → 91% accuracy
• Focus Blast: 70% → 91% accuracy
• Fire Blast: 85% → 110.5% accuracy (capped at 100%)

Overworld Effect

When the lead Pokémon in your party has Compound Eyes:

• The chance for wild Pokémon to hold their common item increases from 45% to 20%
• The chance for wild Pokémon to hold their rare item increases from 5% to 20%

Note: This appears to be a typo in the code comment - it likely increases both rates TO 60% and 20% respectively, not FROM those values. This is a significant boost to finding held items on wild Pokémon!

Common Users

Bug-type Pokémon that often have access to status moves with imperfect accuracy, turning them into much more reliable options. Butterfree with Compound Eyes + Sleep Powder is a classic combination.

Competitive Usage Notes

• Particularly valuable on Pokémon with access to powerful but inaccurate moves
• Synergizes well with status-inducing strategies
• Can enable mixed attackers to run coverage moves they'd normally avoid
• The overworld effect makes it valuable for item collection runs

Counters

• Abilities that prevent status (Insomnia, Vital Spirit for sleep)
• Substitute blocks status moves even with high accuracy
• Magic Bounce reflects status moves back
• Safety Goggles blocks powder moves entirely

Synergies

• Status moves become reliable setup enablers
• Powerful coverage moves become consistent
• Sleep Powder + setup sweeper cores
• Quiver Dance after landing Sleep Powder

Version History

The ability has maintained its 30% accuracy boost throughout generations. The overworld effect for increased held item rates was added in Generation 5 and continues in Elite Redux.
