Steam Engine - Ability ID 243

In-Game Description

"Maximizes Speed if hit by a Fire-type or Water-type attack."

Extended In-Game Description

For use in Elite Redux extended ability UI (IMPORTANT: exactly 280-300 chars counted WITH spaces)

Steam Engine maximizes the Speed stat to +6 stages when hit by any Fire-type or Water-type move. The boost occurs immediately after taking damage, allowing for potential revenge kills or escapes. Works with both direct attacks and indirect damage like entry hazards.

Character count: 286

Detailed Mechanical Explanation

For Discord/reference use

Steam Engine is a powerful defensive ability that converts incoming Fire or Water-type attacks into a massive Speed advantage. Here's how it works:

Trigger Conditions

• Must be hit by a Fire-type or Water-type move
• The move must connect and deal damage (accuracy/hit confirmation required)
• Works regardless of damage amount - even 1 HP triggers the effect
• Activates after damage calculation but before the turn ends

Stat Boost Mechanics

• Raises Speed by 12 stages (the maximum possible boost)
• This equals a +6 Speed stage boost, which is a 4x multiplier to base Speed
• The boost occurs immediately after taking damage
• Uses the same system as abilities like Anger Point (for Attack) and Justified (for Attack)

Activation Requirements

• The ability holder must survive the attack
• ShouldApplyOnHitAffect() check must pass (no substitutes, etc.)
• CanRaiseStat() check must pass (Speed not already maxed)
• Works against both physical and special Fire/Water moves

Strategic Applications

• Excellent for defensive pivots and revenge sweeping
• Turns common attacking types (Fire/Water) into setup opportunities
• Pairs well with bulky Pokemon that can survive strong hits
• Counters popular offensive types in the metagame

Interactions and Edge Cases

• Does NOT activate on:
  • Moves that miss
  • Damage through Substitute
  • Status moves (even Fire/Water-type ones)
  • Indirect damage from items or other abilities
• DOES activate on:
  • Multi-hit moves (each hit can trigger if the first doesn't max Speed)
  • Recoil moves
  • Contact and non-contact moves equally
  • Moves boosted by weather, abilities, or items

Code Implementation

constexpr Ability SteamEngine = {
    .onDefender = +[](ON_DEFENDER) -> int {
        CHECK(ShouldApplyOnHitAffect(battler))
        CHECK(CanRaiseStat(battler, STAT_SPEED))
        CHECK(moveType == TYPE_FIRE || moveType == TYPE_WATER)

        SetStatChanger(STAT_SPEED, 12);
        BattleScriptCall(BattleScript_TargetAbilityStatRaiseOnMoveEnd);
        return TRUE;
    },
};

The ability uses the onDefender hook to trigger when the Pokemon takes damage, checks for Fire or Water move types, and then maximizes the Speed stat using SetStatChanger(STAT_SPEED, 12) where 12 represents the maximum stat stage boost.
