The Hellevater is not often built all at once. Generally, it is slowly built down through the Layers as the character(s) progress the game as a meas to get ores and treasures. They are typially 2 or 3 blocks wide with many horizontal tunnels branching from them.
- Protection: Protecting the tunnel from enemies with blocks on either side even through large cavers is recommended so that traveling characters do not end up being attacked (and potentially knocked off the shaft's path). Doors where there are horizontal tunnels is also a good idea as it prevents monsters from walking into the shaft and falling with the character. Background Walls may also be placed to prevent mobs from spawning in the tunnel, though, this is extreme, especially in large worlds.
- Lighting: Lighting, typically Torches, helps a player know in what part of the shaft his character is as well as illuminating enemies and collectables. Choose one side of the shaft to place them.
- Rope: A character can travel down a rope or chain as fast as falling with out suffering fall damage upon hitting the bottom. Further more, little effort is needed to move back up. Choose the opposite side of the shaft from the lighting to place the rope as they are on the same Placement Layers
- Check Points: Having a check point or outpost at the top or bottom of each level with a bed, campfire, a few Chests with basic needs, and doors allow a character to respawn where he is working without having to travel back every time for being killed or disconnected in Multiplayer. It also serves to provide a hiding place from enemies for low health characters.
- Clear Liquids: Remove all liquids along the Hellevator. This is prehaps the most tedius part of the construction, but well worth the effort. Water can be blocked off and drained, but Lava will either need extensive effort to move, or be made into Obsidian and mined through.
If rope is not used, one of the following options is available:
- 2 blocks deep of Water at the bottom, just before the Underworld begins.
- grappling device, Rocket Boots, any item that allows flight, or use of a Cloud in a Bottle/Balloon shortly before hitting the bottom, although this method requires some timing and accuracy.
- A Lucky Horseshoe or wings are also favorable as they negate all fall damage.
- Place Wood Platforms all along the Hellevator at intervals that are under the falling damage threshold.
