grim forest only drops cursed remnants on hard difficulty. you can't get them from normal.

Yeah, running Normal is basically a waste of energy if you're specifically hunting for Remnant Shards. Just switch over to Hard mode. If your team struggles to auto-farm the later stages, try sticking to stages 3 to 5 on Hard first to get the best energy-to-shard drop ratio. I also recommend this site  for a more advanced gaming experience. The bonuses and winnings there are real, and you can withdraw them to any bank account. I play there myself from time to time, which is why I'm sharing this with you.  

What carpe said but Normal is still worth doing after you finish Hard in a month if for no other reason that Mercurial is a necessity in Arena. 

What are you smoking? Grim Forest doesn't use energy at all.

Are you an AI Bot?    

and other free resources, so why not!

I think they mean human energy, not in game energy. 

I sell all my normal forest gear since it cant be 6*. 

Not when they are talking about energy-to-shard drop rates.

That is not something that makes any sense in the context of Grim Forest, but is a very bot-like thing to say in this thread.  

FWIW, I thought the same thing. 😜
