Neko Nyanyan has a lot of HP. You want Slayers or high damaging Bump Combos to quickly deplete her HP. Cutthroat is also great to have Scorpions will appear in the dungeon. You want to bring Poison or Spread Shot Bump Combos to make your runs faster and smoother. You want to focus on mob clearing. Some of the mobs are in positioned to be pinched so having some Bounce monsters will make things go faster.
