For more information on the Nether, see this page.
The Nether is one of the other dimensions in Minecraft. No Pokémon spawn here, and there are no plans for this to ever be the case. The only differences in the Nether related to Pixelmon are that Fire Stone ore may spawn near lava lakes.
- Blaze rods, Blaze powder, Ghast tears, glowstone dust, Netherrack, Nether quartz, Nether warts, and soul sand are dropped by various Pokémon. However, it is much faster to gather glowstone, Netherrack, Nether quartz, and soul sand in the Nether if large amounts are needed.
- Glowstone blocks can be found in Pokémon Centers.
- A small amount of Netherrack can be found in fiery shrines.
- Wither skeleton skulls can only be obtained from Wither skeletons as in vanilla Minecraft.
