LegionCraft is a OneBlock server where you build up your island and keep expanding your world.
The big thing here is challenging bosses. When you beat them they can drop keys that you use for rare loot.
There are crates with epic gear and rewards so you always have something to grind for. You can also use chunk hoppers to automate your island.
It is also listed as no pay to win so it is meant to feel fair while you build grind fight and loot.
