- The Second Boss have to be beaten
- Go to the 20th floor of the new dungeon

Pandora Box
• Take an Anonymous Magicite
  
• Name it "Pandora Box"
  
• This will give you a Protect + Counter spell

Summon Angora
• Given by Ms.Gossip if you talk to her
  
• Allow you to summon an Angora, who will die for you

Any strong Frost spell
• Any single target spell
  
• At least 25 power, maybe around 20 is fine
  
• The spell I use is called "Falcon Bubble" and I found it

Crosse of Discipline
• Given by an NPC in the Witch's Village
  
• Slightly increases XP gained

This Method allow you to take 1 level per kill until the level 58.
After level 58, you will need 2 or 3 kills to level up again. The method still works, but is no longer safe.

- Go to the 20th floor.
You can go there from the Witch's village directly.
- Cast both "Pandora Box" and "Summon Angora".
- Find a Werewolf.
- Let him kill your angora. Be careful not to get hit.
The werewolf must have gain a level.
- Hit him with your Frost spell. If you halve his HP its good.
- Let him attack you.
He will deals you about 40 damages, but will die from Counter.
- He will gives you more than 10 000xp, so you will fully recover your health by level upping.
- Restart method.
