Detailed Mechanical Explanation

For Discord/reference use

SWIFT SWIM is a weather-dependent ability that provides a significant speed boost under rain conditions.

Activation Mechanics:

• Trigger: Passive - Speed calculation hook (onStat)
• Condition: Rain weather must be active AND affecting the battler
• Multiplier: 1.5x (50% boost) to Speed stat
• Weather Types: All rain variants (WEATHER_RAIN_ANY)

Rain Weather Coverage:

Swift Swim activates under any of the following rain conditions:

1. Temporary Rain: Standard rain from Drizzle, Rain Dance (8 turns, 12 with Damp Rock)
2. Heavy Rain/Downpour: Currently unused in Elite Redux
3. Permanent Rain: Legacy permanent rain (very rare)
4. Primordial Sea: Kyogre's primal weather form

Speed Calculation:

constexpr Ability SwiftSwim = {
    .onStat =
        +[](ON_STAT) {
            if (statId == STAT_SPEED && IsBattlerWeatherAffected(battler, WEATHER_RAIN_ANY)) *stat *= 1.5;
        },
};

Interaction Rules:

• Stacking: Multiplicative with other speed modifiers (Choice Scarf, paralysis, etc.)
• Weather Immunity: Does NOT activate if the Pokémon is immune to weather effects
• Turn Order: Speed boost applies during stat calculation, affecting turn order immediately
• Switch In: Takes effect immediately upon entering battle if rain is already active

Calculation Examples:

• Base 100 Speed → 150 Speed in rain
• Base 100 Speed + Choice Scarf (1.5x) in rain → 225 Speed (100 × 1.5 × 1.5)
• Base 100 Speed paralyzed (0.25x) in rain → 37.5 Speed (100 × 0.25 × 1.5)

Synergistic Abilities and Effects:

• Rain Setters: Drizzle, Primordial Sea
• Compound Abilities: Seaborne (Drizzle + Swift Swim), Way of Swiftness (Pretentious + Swift Swim), Breakwater (Stall + Swift Swim), Atlantic Ruler (Aquatic Dweller + Swift Swim)
• Rain Support: Rain Dish (healing), Hydration (status cure), Thunder (100% accuracy)

Strategic Applications:

1. Rain Sweeper: High-powered offensive Pokémon using the speed boost to outpace threats
2. Rain Support: Fast pivoting and utility moves in rain teams
3. Choice Item Synergy: Scarf users become nearly unstoppable under rain
4. Priority Bypass: Outspeeding priority move users with the speed boost

Competitive Notes:

• Essential ability for rain team offensive cores
• Pairs excellently with water-type attackers benefiting from rain's 1.5x water move boost
• Vulnerable to weather changing (opposing weather setters)
• Completely nullified in other weather conditions
• Thunder becomes 100% accurate in rain, creating powerful special sweeper combinations

• In Elite Redux: Various Pokémon including hybrid abilities that incorporate Swift Swim

Version History:

• Gen 3+: Consistent 1.5x speed boost in rain
