• Forge: 40.2.0 - 40.2.14 with mod: ars_nouveau-1.18.2-2.9.0

Observed Behavior:

when player uses Ars_Nouveau's magic to summon the servants (e.g. skeletons)
it has a chance to summon the mob which has champoins' elite-mobs' flag (e.g. plague)
which would take a bad effect on its master (player) and may cause a series of unexpected results

2. use summon magic in game
