if i remember correctly you have to use the lightning spell on the door above the flower girl's cave at night, if that doesnt work then i forgot how it was done, also the boss fight will make you die several time if you dont go in with a strategy
Appreciate it! just, where do I find the electric spell? I only have fire spell
Do you get it after beating the Millie boss at night? what are the best stats to train for defeating her at lvl 6? not been able to beat her yet :P
