Map Info:
SkyGrind is a minecraft survival map inspired by the old classic SkyBlock map. If you've ever played the original SkyBlock, then this will be very familiar to you.
Instead of Cobblestone Generators, there are spawners which will drop items and blocks that are used to complete quests. Once a quest is complete, you move onto the next island.
There's 20 different areas to explore, with a total of 18 quests to complete throughout the map. There is also a custom stronghold and the Enderdragon to battle against.
