CategoryAbility

Testtests/test_abilities_passive.py::test_berith_gains_pwr_on_enemy_action

When an enemy demon resolves an action, Berith gains +1 PWR status.

Preconditions​

  • Lane 0: P1's Berith (#070) — READIED

  • P2's Duban (#001) resolves an action (ABILITY_USED fires, side=P2)

  • No status effects on Berith

Action​

  • Fire ABILITY_USED event with source=Duban, side=PLAYER_2
from engine.events import GameEvent, EventType, fire_event
    from engine.operations import get_effective_pwr

    state = make_game_state()
    berith = make_demon("070", lane=0, owner=Side.PLAYER_1)
    duban = make_demon("001", lane=1, owner=Side.PLAYER_2)
    state = place_demon(state, berith)
    state = place_demon(state, duban)

    berith_on_field = next(d for d in state.demons if d.unit_id == "070")
    duban_on_field = next(d for d in state.demons if d.unit_id == "001")

    # Enemy demon resolves an action
    event = GameEvent(
        event_type=EventType.ABILITY_USED,
        source=duban_on_field,
        target=None,
        value=0,
        side=Side.PLAYER_2,  # enemy side
        lane=1,
    )
    new_state = fire_event(state, event)

    berith_after = next(d for d in new_state.demons if d.unit_id == "070")
    result = get_effective_pwr(new_state, berith_after)

Expected Postconditions​

  • Berith has 1 active status effect: +1 PWR

  • Berith effective PWR = 4 (base) + 1 (status) = 5

Assertions​

assert result == 5, (
        f"Expected Berith PWR=5 (4 base + 1 from enemy action status), got {result}"
    )
