Illustrious Gateways brings teleporters to Beta 1.7.3:
- Mine iron ore, and have a chance of finding lodestones.
- Craft these lodestones with lapis and redstone to create seeking stones.
- Then, you can further craft seeking stones into seeking gems, or into teleporter blocks. Both are required to use teleporters.
