Touhou LostWord ~ Fire EX Battle Stage 6 Turn (Shion, Saki, Nemuno)
Strategy copied from Minzhire with some change because I don't have Hecatia and to my surprise, I already have enough Nemuno units to limit break.
I feel like I have some accomplishment since Nemuno (B tier) were weaker than Hecatia (S+ Tier) in term of Fire Break. I Replay Auto and Auto Rematch, sleep for 6 hours, after I wake up, It still continues farming. So you don't have to worry much about consistency.
Besides Replay Auto in this battle stage is a pain, sometime Nemuno will Last Word Cirno in turn 4 (Fairy pinned her down afterwards), which made me use my hand to farm this stage with the less unnecessary move as much as possible.
