Netherrack

Netherrack is a collection item found primarily in the Blazing Fortress. It gives +0.5 experience when mined.

Obtaining
Netherrack can be obtained via mining in the Blazing Fortress. It can also be obtained using the Nether Wart Island on the Player's Island.

Usage
Netherrack has no overworld usage other than as a placeable block. It does stay on fire forever, as it does in vanilla Minecraft, however this itself has limited uses in SkyBlock.

It can also be smelted in a furnace into 1x Nether Brick as per vanilla Minecraft.

In Brewing
Netherrack can be brewed in a Brewing Stand with Awkward Potions to create a Wounded I Potion, once Netherrack Collection II has been attained.

However, all further levels of this potion are brewed by using various types of Glowstone with a Wounded I Potion, as usual.

In Trades
Once has been attained, the player can use the Trades menu to trade 1x Netherrack for 1x Nether Brick.

In Crafting
Before 0.11.4, Netherrack is never used for crafting within its own collection. However, it is still used in some crafts throughout the game. It's now used to craft Enchanted Netherrack.

Trivia

 * Smelting Touch pickaxes will automatically smelt the netherrack into nether bricks. This doesn't count towards the collection, so the player must use a pickaxe without smelting touch.
 * Golden Pickaxes can mine netherrack faster than a diamond pickaxe.
 * Netherrack is one of the hardest collections to maintain at #1. The user Presnt is at #1 Netherrack, after forcing the previous #1 Netherrack person, DevoMC, into pursuing #1 Cobblestone.
 * Netherrack is one of the only collections that does not have a Minion, the others being Lily Pad and Ink Sack.
