[jwdpark77]

I keep failing to reach Nightmare 100th floor.
It's so hard, I need help on how to clear it.
What is the easiest way to clear Nightmare 100th floor?

Do you need legal or illegal way to do it?

You have to level up a lot and you get only in the last Zone the Skill pages at a time. You have to enhance all the weapon skills if there is the special office trader wich can come to you every 20 Level after a boss he offers you sometimes for 10 Blue crystals a Ammo amount upgrade Like 5 Granade launcher granades to carry 5 shotgun shells 10 Pistol or 20 Assault rifle rounds. Take this everytime you have the blue crystals to max out the carried ammo. Before you go in tinker at least the amount of HE Hand granades you can carry, tinker the carryable amount of ammo for the SMG and the Magnum. Last but not least make in the 2nd zone some supply runs while carrying water with you. Go in the rooms and use the water on the plants they give you an apple as reward. Before you go in Nightmare carrying 3 Apples restoring instant 50% HP and SP on top of all other heal items is worth much. EVERYTIME have FAT and a fish with you. You can make 10 FAT/LARD out of a fish. If the cat comes give it the fish, if you do the second time the cat meets you it brings you a statusberry in green, red or yellow wich permanently raises HP, AG or SP. I used over 40 of each and it still no cap. No worries of the cat takes you fish and goes away and you are trough a zone not meeting it a second time. If you met it another time elswhere the cat remembers you last fish gift and brings the berry as reward. No matte when, every fish brings you a random Stat-berry. Im not so good in the fast rat thief minigame and sometimes screw it up. For this you should have the fat/lard. Its the rats favortie food and it steals it instead of the 10 times more expensive fish wich you then not have when meeting the cat. My record was 148 and i had LOTs of Heling and plenty SP Items but no single shoot of Ammo. My problem is running out of Ammo, and i save a lot with kicks and Pistol use in the beginning. Hope it could help a bit.

BTW you can have 9 Apples in your inv at once wich give 50%HP and 50%SP on use. I did take 3-5 in the past on a run as a heal backup, cause my problem was Ammo. I don´t have farmed any apples farer than 9 but maybe its possible to have even more in your inv. Im now Level 300 with 18 Times Mammon-Potion downrank but still have over 20 Pages of Skills in my inv and lack of Violet Mammon ore to create more downlevel potions to use em. I focus now on the weapon masterys, -3%DMG inc +5% Firepower and the +Ammo-Carry Pages wich you can some times buy at the asian office salesman sometimes wich comes every 20 nightmare levels after a boss in the construction tunnel. Sometimes he offers you a Skillpage for 10 Blue mammon ores that expands your Ammo carrying cap for a single weapon. Buy this instantly if you have the ore. Even Rarer he offers an artifact. Buy it if you can afford it. Priorize the Ammo Carrying and Artifacts over making Mammon Potions.
In late game you make Potions to downrank a level so you can get another perk point. I think there are 400-500 Skill Pages and you can get normally 300 Perk Points at Level 300 but Leveling is insane fast. Think the rest you have to get via Mammon-Potion down- and uplevel. It costs Mommon ore you find at some special Elite in the nightmare Tunnel. The blues are in the side rooms. Have Almost 200 blue Ores and 60 red ores. From The Arifacts i have the Flashlight wich prevents setback by detours and the lighter wich makes the Molotov cocktail explode for Additional +20% DMG wich hit also yourself.
