Detailed Mechanical Explanation

For Discord/reference use

Core Mechanics

Toxic Spill is a field control ability that creates a persistent toxic waste environment. When a Pokémon with this ability enters battle, it announces the toxic spill and begins damaging all non-Poison-type Pokémon at the end of each turn.

Activation Conditions

• Entry trigger: Activates immediately when the Pokémon enters battle
• Field persistence: Effect continues while the user is on the field
• Exit cleanup: Toxic waste dissipates when the user switches out or faints
• Poison type immunity: Poison-type Pokémon are completely immune to damage
• Monotype exception: Doesn't activate in Poison-type monotype champion battles

Damage Mechanics

• Damage amount: 1/8 of the target's maximum HP per turn
• Timing: Activates during end-of-turn phase
• Type immunity: Only affects non-Poison-type Pokémon
• Magic Guard bypass: Deals damage even to Pokémon with Magic Guard
• Toxic Boost immunity: Pokémon with Toxic Boost are protected from damage

Technical Implementation

constexpr Ability ToxicSpill = {
    .onEntry = +[](ON_ENTRY) -> int {
        CHECK_NOT(getMonotypeChampType() == TYPE_POISON)
        BattleScriptPushCursorAndCallback(BattleScript_BattlerAnnouncedToxicSpill);
        return TRUE;
    },
    .onEndTurn = +[](ON_END_TURN) -> int {
        // Check for source abilities (Toxic Spill or Trash Heap)
        int any = FALSE;
        for (int target = 0; target < gBattlersCount; target++) {
            FILTER(IsBattlerAlive(target))
            
            // Poison Heal interaction - heal instead of damage
            if (BATTLER_HAS_ABILITY(target, ABILITY_POISON_HEAL)) {
                // Heal the target instead of damaging
                gStackBattler1 = target;
                BattleScriptExecute(BattleScript_ToxicWasteHeal);
                any = TRUE;
                continue;
            }
            
            // Skip Poison types, Magic Guard, and Toxic Boost
            FILTER_NOT(IS_BATTLER_OF_TYPE(target, TYPE_POISON))
            FILTER_NOT(IsMagicGuardProtected(target))
            FILTER_NOT(BATTLER_HAS_ABILITY(battler, ABILITY_TOXIC_BOOST))
            
            // Deal 1/8 damage
            gStackBattler1 = target;
            BattleScriptExecute(BattleScript_ToxicWasteTurnDmg);
            any = TRUE;
        }
        return any;
    },
    .onExit = +[](ON_EXIT) -> int {
        CHECK_NOT(getMonotypeChampType() == TYPE_POISON)
        BattleScriptCall(BattleScript_TheToxicWasHasDissapeared);
        return TRUE;
    },
};

Special Interactions

• Poison Heal synergy: Pokémon with Poison Heal recover HP instead of taking damage
• Magic Guard bypass: Unlike most passive damage, this bypasses Magic Guard protection
• Toxic Boost protection: Pokémon with Toxic Boost are immune to the damage
• Type immunity: Only Poison-type Pokémon are completely immune
• Multi-source stacking: Multiple sources (Toxic Spill + Trash Heap) don't stack damage

Battle Messages

• Entry: "{Pokémon} has spilled Toxic Waste on the field!"
• Damage: "{Pokémon} is hurt by the toxic waste!"
• Healing: "{Pokémon} restored HP using its Poison Heal!"
• Exit: "The Toxic Waste has disappeared!"

Strategic Applications

• Passive damage dealer: Excellent for wearing down opponents over time

Trash Heap Connection

Toxic Spill is also part of the Trash Heap ability (ID varies), which combines:

• Toxic Spill effects: All field control and damage mechanics

• Poison Heal: Turns damage into healing
• Toxic Boost: Provides immunity to the damage
• Switching: User must stay on field to maintain effect

• Rapid KO: Fast elimination prevents prolonged damage

Team Synergies

• Poison teams: Natural immunity allows aggressive switching
• Stall teams: Provides passive damage while stalling
• Pivot Pokémon: Can switch in, cause damage, then pivot out
• Entry hazard stackers: Combines with hazards for multiple damage sources
• Healing support: Pairs with healing to outlast opponents

Competitive Viability

• Doubles format: Affects all opponents simultaneously
• Singles format: Forces opponent switching and creates pressure
