Weird knowledge

Ryan frowned when he heard those names. Doppelgangers were basically a monster than can transform into their enemies… Ryan was pretty sure that such skill was the low-level version of whatever skill the dungeon system uses to make copies of the bosses.

"Doppelgangers are fake copies of yourself, they consume a lot of mana to exist, but since they don't have a physical form, they can keep attacking as long as you have mana," Femradiel said.

"I don't think that fits my style, I already consume too much mana on my own," Ryan said. 

"While increasing the output of my attacks seems interesting, there is no meaning if I can't maintain it for more than a few seconds."

"That is true, but I was thinking of making a doppelganger of myself, I have a lot of mana stored, after all. While that will cost me a lot, it is a skill I truly want to level up and one day, master."

"Did you really give up on recovering your body?" Ryan asked.
