The Diamond Dimension is a dimension added by MoreDimensions.
Entering and Exiting the Diamond Dimension
Entering the Diamond Dimension is similar to entering The Nether. However, instead of using Obsidian, Blocks of Diamond are used. Additionally, the portal is activated with a Diamond Igniter rather then Flint and Steel.
Similar to The Nether, when entering the Diamond Dimension another portal is auto-generated within the new dimension.
The Diamond Portal makes noise, like the Nether Portal.
The Diamond Dimension's world generation is similar to The Overworld, but it generates Blocks of Diamond and Diamond Ores rather than Grass and Dirt and Stone.
Like The Overworld, the Diamond Dimension has a sequence of day and night, but without rain.
There are no mobs implemented in the Diamond Dimension yet.
