[Soul Burst: After Your Life is Decreased] Exhaust 1 opposing Spirit. Afterwards, destroy all opposing exhausted Spirits, and for each Spirit destroyed by this effect, add one core from the Void to your reserve. After that effect resolves, if your life is 3 or less, summon this Spirit card without paying the cost.
[LV2][LV3] (When Attacks) When only the opposing Spirit is destroyed by BP comparison, send two cores each from any opposing Spirits and Life to the Void.
