just the easier guide for unlocking Necromancer
steps
I prefer personal Fire Knight the most Because he has a good extent of injury Magic

And I chose Fire Knight for that
After the end of the game insane mode will open up
Then playing to reach up to Industrial Castle in insane mode
beat up the level and you have him
then enjoy your new character
