How to fight against the black witch in Du Fei's story?

First of all, you have to go through the palace and the goblin forest to get the proficiency certificate and upgrade the mage. If you choose an elf warlock, you can do whatever you want.

1, grade 12 or above, prepare 5 or 6 explosion flasks and 7 or 8 flame flasks, with enough medicine and blood thickness to prevent teammates from losing at high speed, and almost die when they see it (P.S. blood about 1500).

2. If the level is above 20, please feel free to call.

Unari in Aguedu will win the "Witch of Belamé a" after defeating the thief boss. The weakness is that the fire is there.
