Detailed Mechanical Explanation

For Discord/reference use

Vengeful Spirit is a powerful combination ability that merges two distinct effects:

Haunted Spirit Component (.onDefender)

• Trigger: When the Pokémon is KO'd by a contact move
• Effect: Applies Curse status to the attacker (STATUS2_CURSED)
• Damage: Cursed Pokémon lose 1/4 of their max HP each turn
• Immunities:
  • Ghost-type attackers are immune
  • Attackers already cursed are immune
• Contact Requirement: Only works against moves that make contact

Vengeance Component (.onOffensiveMultiplier)

• Trigger: When using Ghost-type moves at low HP
• Condition: Pokémon must be at 1/3 HP or less
• Effect: 1.5x damage multiplier for Ghost-type moves
• Implementation: Uses SWARM_MULTIPLIER(TYPE_GHOST) macro

Technical Implementation

constexpr Ability VengefulSpirit = {
    .onDefender = HauntedSpirit.onDefender,
    .onOffensiveMultiplier = Vengeance.onOffensiveMultiplier,
};

The HauntedSpirit.onDefender function:

.onDefender = +[](ON_DEFENDER) -> int {
    CHECK(ShouldApplyOnHitAffect(attacker))
    CHECK_NOT(IsBattlerAlive(battler))
    CHECK_NOT(IS_BATTLER_OF_TYPE(attacker, TYPE_GHOST))
    CHECK_NOT(gBattleMons[attacker].status2 & STATUS2_CURSED)
    CHECK(IsMoveMakingContact(move, attacker))

    gBattleMons[attacker].status2 |= STATUS2_CURSED;
    BattleScriptCall(BattleScript_HauntedSpiritActivated);
    return TRUE;
},

The Vengeance.onOffensiveMultiplier uses SWARM_MULTIPLIER:

#define SWARM_MULTIPLIER(type)                                               \
    +[](ON_OFFENSIVE_MULTIPLIER) {                                           \
        if (moveType == type) {                                              \
            if (gBattleMons[battler].hp <= (gBattleMons[battler].maxHP / 3)) \
                MUL(1.5);                                                    \
        }                                                                    \
    }

Competitive Applications

1. Defensive Punishment: Deters physical attackers from making contact
2. Revenge Kills: Low HP Ghost moves become extremely powerful
3. Pivot Potential: Forces opponents to choose between curse damage or switching
4. Ghost-type Synergy: Pairs excellently with Ghost-type movesets
5. Anti-Physical: Specifically counters contact-based physical attackers

Strategic Usage

• Setup Sweepers: Can threaten curse while setting up
• Revenge Killers: Becomes dangerous when brought in at low HP
• Pivot Pokémon: Forces difficult decisions for opponents
• Wall Breakers: Low HP Ghost moves can break through defensive cores
• End Game: Curse damage can secure late-game victories

Notable Interactions

• Magic Guard: Prevents curse damage to Magic Guard users
• Ghost-types: Immune to the curse effect but not the damage boost
• Non-contact moves: Bypass the curse effect entirely
• Status moves: Don't trigger the offensive multiplier
