The Teleportal Mod adds the possibility to build an infinite amount of portals which make travel distances in Minecraft so much shorter. For example, set up a portal deep down underground where you are mining precious metals and set up a second portal above ground at your house to be able to go between the two places very fast.
To create a portal you will need 16 pieces of any type of solid block
Tap on the bottom-left or bottom-right corner block with flint & steel to activate the portal.
