Nostrum

A Pot Luck Nostrum.

Nostrums were the passive abilities of BioShock Infinite, similar to the Gene Tonics of the other BioShock games, before being replaced by Gear. They were permanent character upgrades, and had no need to be equipped or managed. Nostrums allowed Booker DeWitt to be upgraded in a manner that suited a player's style. There was to be no limit to the amount of Nostrums that can be used. The player would have also come across unstable Nostrums, labelled "Pot Luck", which would've granted the user a choice of three different abilities. Once one Nostrum was chosen from those three, it could not be removed.

Planned Nostrums

• Executioner: For Melee.
• Spring-Heeled: For Movement.
• Winter Shield: For Skylines.

Trivia

• The Nostrum Pot Luck uses the same three-option selection mechanic as Infusions in the final game.
