These ten floors are your last chance to stock up on Revives before the final battles. You should also stock up on Medicine 3 and 4 as well. Hopefully, you have boosted the attack and defense of your weapon and armor to above 500. Anything less, and you'll find things a little difficult, especially the boss on the 70th floor. If you were able to get PE Light onto your armor, that will help conserve PE by decreasing the amount your Parasite Powers(except Energy Shot and Liberate) consume by half.

 The giant Bee on 70 will be your biggest challenge up to this point. It has a "lightning attack" which reduces your defense, and a barrier wall attack which comes fast and has a wide range. you'll also have to deal with smaller bees which will come every now and then. They will cure the Queen and attack you as well. If you have Burst on your weapon, you should be able to hit the queen and the smaller bees at the same time. You get the final key, Chrysler Key 7, for winning.
