If you want Nether Brick but don't wanna use your valuable Grass to buy some, try going to the Nether and digging up Netherrack. You then wanna smelt this Netherrack in a Furnace to get Nether Brick items. Combine 4 Nether Bricks to get 1 Nether Brick block. This process may be a little slow, but its cheap and its possible for anyone to do this. Either if you're a Top-Ranked Donor or a rather New Player, this is very easy to do. You may wanna find an Island with a Portal though. Just go asking around.
