CategoryAbility
StatusPassing
Testtests/test_abilities_passive.py::test_buer_heals_allies_on_exhaust

When Buer exhausts, all other local allied demons have damage

Preconditions​

  • P1 Main Phase

  • Lane 0: P1's Buer (#014) — READIED, base PWR=3, 0 damage

  • Lane 0: P1's Duban (#001) — READIED, 5 damage (ally, same lane)

  • No other demons in lane 0

Action​

  • Fire DEMON_EXHAUSTED event with source=Buer
from engine.events import GameEvent, EventType, fire_event

    state = make_game_state()
    buer = make_demon("014", lane=0, owner=Side.PLAYER_1)
    duban = make_demon("001", lane=0, owner=Side.PLAYER_1, damage=5)
    state = place_demon(state, buer)
    state = place_demon(state, duban)

    buer_on_field = next(d for d in state.demons if d.unit_id == "014")
    duban_on_field = next(d for d in state.demons if d.unit_id == "001")

    # Fire DEMON_EXHAUSTED event with Buer as source
    event = GameEvent(
        event_type=EventType.DEMON_EXHAUSTED,
        source=buer_on_field,
        target=None,
        value=None,
        side=Side.PLAYER_1,
        lane=0,
    )
    new_state = fire_event(state, event)

    duban_after = next(d for d in new_state.demons if d.unit_id == "001")

Expected Postconditions​

  • Duban's damage reduced by 3 (Buer's PWR): was 5, now 2

  • Buer's damage unchanged: 0

Assertions​

assert duban_after.damage == 2, (
        f"Expected Duban damage=2 (5-3 from Buer PWR), got {duban_after.damage}"
    )
