Lab coat
Effects needed: Healing aura, Wrench (to get money)
Money needed: 10 N
Follow the instructions for the Healing Aura, but don’t leave the Hospital. Instead, go up to the third floor, walk all the way to the left and use the effect on the green (+) spot, facing the glitched door. Enter the room. You’ll see there’s only a phone booth inside. Pay 10 N for the phone booth and it will take you to Streetlight World. Walk south-southwest to find a Subway entrance. Instead of the Scooter and 100 N, you only will need the Healing Aura to enter, since there’s a glitch between the second and third stations that can only be fixed if you enter from here. You don’t need to “heal” the glitch in order to access the second station, but if you do these stations will be unlocked forever, and you won’t need to use the phone booth method anymore (at the cost of having to pay 100 N like in the rest of stations). The second station has a “^^” mark on it. Go up the stairs and you’ll arrive at the Nice Town. The map is only 20 tiles wide and loops horizontally, so you just have to walk north all the way. There’s only one blind alley, and you can easily go back and try another path. Next is a small square that can be left by walking north as well. You’re now at the High School. Go up the stairs to reach the first floor. Now go down the other stairs and walk through the long hall to find a humanoid NPC with dragon wings. Talk to him. He’ll show you the other NPCs you have to find. Considering you’re in Floor 0 and Floor 1 is the entrance, the first two NPCs can be found in Floor 2, the next two in Floor 3, and the last one in Floor 4. Once you find and talk to them all, you will be teleported back to the place with the winged NPC, who is now having a party with his friends. Talk to him and he will give you the effect.
