Also known as: ネザーゲート
A manufactured structure that acts as a gateway between the Overworld and The Nether (Minecraft) dimensions. A Nether portal is built as a vertical, rectangular frame of Obsidian Rock (4×5 minimum, 23×23 maximum size). The four corners of the frame are not required. Once a frame is constructed, it is activated by fire placed inside the frame. This creates purple, light-emitting portal blocks inside the frame, resembling a vortex. It produces whooshing noise regularly.
Such incomplete frames of obsidian are often found in naturally-generated ruined portal structures.
It can be destroyed by Explosions, flowing lava or Water into the portal block or by simply Mining its obsidian frame.
There are also rumors about a variant of this portal using glowstone and water…
