Detailed Mechanical Explanation

Snow Warning automatically creates a hailstorm when the Pokémon enters battle, providing the same effect as the move Hail without consuming a turn.

Trigger Conditions

• Activates upon entering battle (switch-in, battle start, or after fainting an opponent)
• Uses the onEntry hook to trigger weather change
• Blocked if primal weather is already active

Weather Duration

• Base Duration: 8 turns (standard WEATHER_DURATION)
• Extended Duration: 12 turns with Icy Rock held item
• Duration counts down at the end of each turn

Hail Effects

1. Damage Per Turn:

   • Deals 1/16 max HP damage to all non-Ice-type Pokémon
   • Pokémon immune to hail damage:
     • Ice-type Pokémon
     • Pokémon with Ice Body, Snow Cloak, Overcoat abilities
     • Pokémon holding Safety Goggles

2. Move Changes:

   • Blizzard: 100% accuracy (normally 70%)
   • Weather Ball: Becomes Ice-type and doubles in power
   • Solar Beam/Solar Blade: Power reduced to 50%
   • Moonlight/Morning Sun/Synthesis: Restore 1/4 HP instead of 1/2
   • Aurora Veil: Can only be used during hail

3. Ability Interactions:

   • Ice Body: Restores 1/16 HP per turn instead of taking damage
   • Snow Cloak: +25% evasion
   • Slush Rush: Doubles Speed
   • Forecast: Castform becomes Ice-type

Special Interactions

• Primal Weather: If Desolate Land, Primordial Sea, or Delta Stream is active, Snow Warning fails and shows "blocked by primal weather" message
• Weather Override: Can replace other non-primal weather effects
• Simultaneous Activation: If multiple weather setters enter together, Speed determines order (fastest overwrites)
• Cloud Nine/Air Lock: These abilities suppress hail damage and effects

Implementation Details

• Uses TryChangeBattleWeather(battler, ENUM_WEATHER_HAIL, TRUE)
• Executes BattleScript_SnowWarningActivates for message/animation
• Returns NO_ANNOUNCE if blocked by primal weather
• Standard weather mechanics apply through the weather system
