The Tessaract

'An upgrader from the fourth dimension that upgrades bigger ores by more. Beware though, using this item takes away half of the ore sent through. Built by Mah_Bucket"'

The Tessaract is a relatively unique item added to AHR that is obtainable from rebirth at any life.

Trivia

 * This item is the first to base itself entirely around the size of an ore.
 * Using something like Massive Diamond Mine, or Ol' Faithful would be extremely beneficial when paired with this upgrader.
 * As of the Nostalgia Event, this item now takes half of an ore's size when it goes through.
 * This item destroys any ore below the size of 1x1x1 that go through it.
