If you're looking to complete the "Supreme Helper Minion" achievement without waiting for a new day in Terraria, then this map is for you!
Steps:
1. Download the map and move it to the "Worlds" folder (C:\Users\User\Documents\My Games\Terraria\Worlds)
2. Copy the WLD file and paste it in the same folder 200 times (less if you already have some quests done)
3. Launch Terraria
4. Start one of the copies
5. There is a chest to the left of the spawn filled with Catfish (that's the quest fish for our Angler). Fill your inventory up with the fish.
6. Submit the quest fish to the Angler
7. Exit the map and start up another copy of it. You should be able to submit the fish again.
8. Repeat until you get the achievement.
Always be sure to start a different copy of the map.
