QUESTIONS:
Where to get Energy Fragment?
Do the Instance EDDA Biolabs, some mobs drop it there with a low drop chance so use HE Bbgum for better chances.
Where to get Cursed/Grudge Fragments and Fragment of Vicious Mind?
They drop in "Tomb of the Fallen" Dungeon. Prefer to use Cursed Water while farming.
Thanks for reading and Goodluck!
