i wanna know who beat doppelganger before not using lost weapons and nt lvl 100, i just tried he appeard in a random area i was 89 with endrance and khun and i gothim to half health before he beat me i couldnt win, the only lost weapon i have i my scythe for haseo and i didnt use it

I met doppleganger at first when Haseo already at 100 and got his lost weapon. But, actually doppel it's just easy to beat when Haseo was accompany by the party that already have pink affection. You know why? cuz it can give more damage when we use Divine Awakening. So, the tactics is we must use the party that have rapid attack such as Alkaid (but she become A lost one in reminisce), Silabus, or Endrance. Then add the material that make rengeki faster(i forgot the name). and don't forget, invite Atoli to your party!! so, we can continually use rengeki on it, and it's mean that the morale bar will fill quicker. After the morale bar was full, use the Divine Awakening. Repeat and repeat again till death invite him.

hahah actually i know a easier way,use endrance with his lost weapon, it will make doppelganger have heart above head and try to run, use endrance, and another high dmg guy when endrance has his lost weapon

Do you read my post wholly? I said Endrance right, actually I also want to tell you that same way, but I just forgot. His lost weapon make doppelganger charm right?

yeh, thats wat make it so easy lol
