Impure World Reincarnation could be used as traps

[Alfred Pennyworth]

set up the seal formation underground , and prepare someone's DNA
wait for enemies to unknowingly step into the formation
activate the summoning seal , then the enemy would become a sacrifice
once the dead person is completely summoned , the sacrifice will theoretically die
