Ok, so, last night, after about 6 months of tearing my hair out, I finally dodged 208 lightning bolts and claimed the sigil, got my Onion Knight all powered up, so I'm relatively happy.
However, this means that I now only have 1 more weapon to power up, this being Khimari's Spirit Lance (as if you hadn't guessed), so, does anyone have any tips / maps for me to get past this damn butterfly game?
