Requirement: Ascension 4 (R220+)
This set of upgrade appears with no other unlock requirement.
With each Legacy Container you can choose a Legacy (equal to the set of 3 faction upgrades of the same tier) that doesn't match your current faction.
This unlocks those 3 faction upgrades for purchase for their normal coin cost (see faction upgrade costs at Ascension 4).
You can purchase more Legacies for a progressively increasing cost.
The current limit is 4 Legacy Container  not including the special one granted by the Research Relativity (F11750).
Coin Cost: (1e72 * (1,000 ^ (x ^ 2  x))), where x is your current Legacy container.
Faction Coin Cost: (1e33 * (1,000 ^ ( 0.5 * ( x ^ 2  x)))), where x is your current Legacy container.
Note: While the Container from Relativity is free to purchase, the granted upgrades still have their normal coin cost. It also does not influence the cost of the other container.
