CategoryAbility
StatusPassing
Testtests/test_abilities_passive.py::test_duban_not_stacks_with_itself

Two separate Duban units on the field. Each has its own +5 DEF —

Preconditions​

  • Lane 0: P1's Duban (#001) instance A — READIED

  • Lane 0: P1's Duban (#001) instance B — READIED

Action​

  • Query get_effective_def for Duban A
result = get_effective_def(state, duban_a_on_field)
    # Duban's passive is registered as a self-modifier (no "Other" check),
    # but get_passive_modifiers only calls it for the queried demon.
    # A second Duban doesn't grant aura DEF to the first.

Expected Postconditions​

  • Returns 5 (own passive only; Duban passive is self-only, not an aura)

Assertions​

assert result == 5, f"Expected DEF=5 for single Duban passive (self-only), got {result}"
