It could forcefully fight for the control of an undead unit with the enemy. This process would last for about 3 to 15 seconds, depending on the intensity of the fight. After 15 seconds, even if the two sides were still in a stalemate, the instigation would be considered a failure.
However, the most annoying part of this spell was that there was almost no loss after failure. Since the battlefield for control was on someone else's undead, the person who actively cast it would not even suffer from the common punishment of losing focus and weakening spirit.
Once it succeeded, the undead who had been instigated to defect would be treated as a " temporary unit " and directly join the battle.
Although temporary units could not self-destruct, when the two armies were fighting, the damage caused by a sudden betrayal in the formation was enough.
However, even though it seemed like a good idea to continuously cast instigation, the effect wasn't that great.
