I just did enough pumpkin runs to get to 500 life crystals for a rainbow skill bloom. The pumpkins I spent on 11 DEF ampys, since I already had the ATK ampys and all the manyus.
So, now I'm going to focus on Lavender and getting her some blooms (which are gladly much cheaper).
Tomorrow is red/blue manyu day though, and I could still use a LOT of red manyus.
