You can use this mod with any map and it will be both fun and useful, not just Skyblock. Still, I recommend using the original Skyblock map by Noobcrew.

Blocks and items added by this mod:

Barrels

Hammers

Crook

Silkworms

Sieves

Crucibles

Agriculture

Stones

Dolls

A note on world generation.

This mod adds some extra world generation options, but they are disabled by default.
To turn them on, you'll have to go into the config settings and locate the following section.

If you turn these settings on, then any new chunks generated in those areas will be void chunks. This is perfect for getting rid of that nasty exploit of building a bridge to land in skyblock maps. This also allows you to get perfect and endless void nether and end dimensions.

Warning!
If you choose to generate the nether as a void dimension, you will not be able to find 'nether fortress' chunks and spawn blazes. Hunting invisible fortresses sucked. If you want to find nether fortresses, enable the nether_fortresses_allowed option. This will allow fortresses to spawn in the void. You'll be able to see them too!

What this mod adds 25 types of Quicksands? That naturally generate around whole world. And if you don't like any one particular type, you can toggle it's generation off in the config file.

What mod is contain:

• • 25 types different Quicksands with its naturally generations.
  • 3 Mobs Slimes, that only want to devour you if you will be too careless.
  • New Structure - Desert Tombs, that contain many useful loots but also have dangerous traps.
  • Ultimate Covering System that covers every players and shows how dirty they will looks after taking an bath in an types. This System is compatible with most Animation Mods, but also it's switchable option.
  • Unlike other mods you can swim under surface of Quicksand without any risk of taking damage, but when you would out of breath you will start dying in it. Because Quicksand is not Water you cant use any Water Breathingstuff in it. This is also switchable option.
  • Stuff/Items/Tools that increase your chance successful hiking without being a victim of deadly nature traps, as:
    • Long Stick - using as walking stick for testing grounds in front you.
    • Wading Boots - that allow you walking on swampy surface without worrying (Almost  )
    • Life Jacket - that gives you additional buoyancy.
    • Rope and Grappling Hook - that allow you get out of some sticky situations or help other players.

The main reason that I developed this mod is that the standard types of quicksand, like the ones in BiomeOPlenty have cobweb physics. That means that if you're stuck in it, you have to dig the blocks under you, before you hit solid ground. Also you can fly away or use a hook, teleport or something else. But this is too boring and annoying!

In contrast of this, my Quicksand has a more complex structure that is described below.

Adds 24 Dungeons, 3 Bosses and 2 Villages!

Basically, this mod will add more generated structures, mobs, weapons, blocks, and much more!
