Angor would have already fallen if Felicia meant to get him for real. Thankfully, the witch never planned to use her wizard-level strength to stop the intruder.
The third butterfly she unleashed already contained most of her true power. It would have no problem destroying the entire lobby including that apprentice.
Felicia disliked Diablo's mentor a lot, but she would admit that Puppet Master was very likely to become a "truth finder" wizard, which meant the same level as Sunders. Of course, that man would still be a lot weaker than Sunders even if he made it.
Felicia wouldn't want anyone to intrude Dark Castle and disrupt Greya's rest. However, she wouldn't kill the intruder yet, considering her agreement with Puppet Master.
She wouldn't stop Angor from saving Diablo… as long as Angor didn't come and bother Greya first.
She lifted her crystal ball again to check the prison area.
