In Terraria, there are 6088 items, and 5821 of them are renewable — meaning that you can theoretically obtain each of them in unlimited quantities. And on this Skyblock map, you can get them all with minimun amount of resoursers to start!

Using just a 4x5 world you can:

Defeat every boss in the game
Obtain all biomes and mini-biomes
Trigger all events
Get every NPC and mob

This map is a middle ground among skyblocks: not too easy like the official skyblock, but it also doesn’t require hours of grinding like other skyblocks. The map requires a deep understanding of the game’s mechanics, so don’t hesitate to check this guide. Also check sheet, which was created just to understand, which items in Terraria are actually renewable.
