Detailed Mechanical Explanation

For Discord/reference use

Core Mechanics

Furnace is a reactive ability that converts Rock-type damage into Speed boosts. It provides immediate Speed increases through two distinct triggers, making it a powerful momentum ability for Pokémon that can survive Rock-type attacks.

Activation Conditions

The ability has two separate activation mechanisms:

1. Switch-In Activation (.onEntry)

• Trigger: When switching in with Rock-type Stealth Rock present on the field
• Requirements:
  • SIDE_STATUS_STEALTH_ROCK must be active on the battler's side
  • stealthRockType must be TYPE_ROCK (not Grass-type Creeping Thorns)
  • Battler must be alive after switching in
• Effect: Grants +2 Speed stages immediately upon entry
• Script: Uses BattleScript_AttackerAbilityStatRaiseEnd3

2. Hit Reaction (.onDefender)

• Trigger: When hit by Rock-type moves during battle
• Requirements:
  • ShouldApplyOnHitAffect(battler) - move must hit and deal damage
  • moveType == TYPE_ROCK - attacking move must be Rock-type
  • CanRaiseStat(battler, STAT_SPEED) - Speed must be raisable
• Effect: Grants +2 Speed stages after taking Rock-type damage
• Script: Uses BattleScript_TargetAbilityStatRaiseOnMoveEnd

Technical Implementation

constexpr Ability Furnace = {
    .onEntry = +[](ON_ENTRY) -> int {
        CHECK(gSideStatuses[GetBattlerSide(battler)] & SIDE_STATUS_STEALTH_ROCK)
        CHECK(gSideTimers[GetBattlerSide(battler)].stealthRockType == TYPE_ROCK)
        CHECK(IsBattlerAlive(battler))
        CHECK(ChangeStatBuffs(battler, 2, STAT_SPEED, MOVE_EFFECT_AFFECTS_USER, NULL))

        BattleScriptPushCursorAndCallback(BattleScript_AttackerAbilityStatRaiseEnd3);
        return TRUE;
    },
    .onDefender = +[](ON_DEFENDER) -> int {
        CHECK(ShouldApplyOnHitAffect(battler))
        CHECK(moveType == TYPE_ROCK)
        CHECK(CanRaiseStat(battler, STAT_SPEED))

        SetStatChanger(STAT_SPEED, 2);
        BattleScriptCall(BattleScript_TargetAbilityStatRaiseOnMoveEnd);
        return TRUE;
    },
};

Important Interactions

Stealth Rock Synergy

• Activation requirement: Only works with Rock-type Stealth Rock, not Grass-type Creeping Thorns
• Entry hazards: Triggers immediately when switching in if Rock Stealth Rock is present
• Damage timing: Speed boost occurs after taking Stealth Rock damage on switch-in
• Multiple activations: Can trigger on both switch-in and during battle with Rock moves

Battle Mechanics

• Hit requirement: Must take actual damage from Rock moves to trigger during battle
• Multi-hit moves: Can potentially trigger on each hit of multi-hit Rock moves
• Status protection: Ability functions normally even if Pokémon has status conditions
• Stat boost caps: Cannot raise Speed beyond +6 stages maximum

Ability Interactions

• Mold Breaker: Furnace can be suppressed by Mold Breaker and similar abilities
• Simple: If paired with Simple ability, Speed boosts become +4 instead of +2
• Contrary: Would reverse the Speed boost into a Speed drop if somehow combined
• Magic Guard: Protects from Stealth Rock damage but still allows the Speed boost

Strategic Applications

Team Building Synergy

• Rock-weak Pokémon: Transforms Rock weakness into Speed advantage
• Offensive sweepers: Provides immediate setup opportunity after taking Rock damage
• Stealth Rock punishment: Punishes common entry hazard with Speed boosts
• Momentum building: Creates instant sweeping potential from defensive switches

Competitive Usage

• Entry hazard meta: Excellent in metagames with heavy Stealth Rock usage
• Rock-type counters: Can safely switch into Rock moves for Speed boosts
• Speed control: Provides immediate Speed tier advantage after activation
• Surprise factor: Opponents may not expect Speed boosts from Rock attacks

Common Scenarios

• Stealth Rock switch-in: Gain +2 Speed when switching into Stealth Rock
• Rock move survival: Tank Rock moves for Speed boosts and counterattack
• Edge Quake response: Turn common EdgeQuake strategies against opponents
• Hazard stacking: Benefit from opponent's Stealth Rock setup

Counters and Limitations

Direct Counters

• Ability suppression: Mold Breaker, Neutralizing Gas, and similar abilities
• Speed control: Trick Room reverses the Speed advantage
• Status conditions: Paralysis can negate Speed boosts
• Choice items: Speed boosts don't help if locked into the wrong move

Situational Limitations

• Rock immunity: Flying types with Air Balloon avoid Rock Stealth Rock
• Heavy Duty Boots: Prevents Stealth Rock damage and thus the entry boost
• Type changes: Becoming Rock-resistant removes the hit activation
• Magic Bounce: Can reflect Rock moves before they trigger Furnace

Strategic Limitations

• Setup requirement: Needs Rock moves or Rock Stealth Rock to activate
• Health cost: Takes damage to gain Speed (except potentially with Magic Guard)
• Timing dependency: Opponent controls when Rock moves are used
• Single activation: Each Rock hit only gives one boost, not cumulative
