First of all this oc is a glass cannon but typically stays outside of the fight without the attacker noticing
Basically he overwhelms the attacker with illusions of actual magic at random from any known coven ( an example being summoning an abomination that’s actually just an illusion) after this the fight can end three ways
1. the attacker doesn’t notice that the illusions are illusions and eventually he takes them out with magic he actually knows ( randomly switching from illusions to actual abilities , like for example a vine cage )
2. The attack figures out the illusions are fake and makes the assumption that he only knows illusion spells ( this ends the same way as the first, except the switch is more purposeful sense the attacker “ learned “ the trick and would likely begin to go after him directly instead of the illusions )
3. The attacker finishes attacking the illusions and he’s already gone, the illusions were just a distraction to get away quick ( only really done if the attacker is clearly to strong to take on or if he gets bored )
Tldr my oc pretends to fight people for fun and eventually takes them out when they realize he’s playing them or if he gets tired
