Sheldon License



Sheldon Licenses are a type of currency introduced in that can be used to acquire new weapons in Ammo Knights, which differs from previous games where players instead used Cash.

Sheldon Licenses can be obtained by increasing the player's level and by increasing a weapon's Freshness to 1 star. Each weapon costs 1 Sheldon License to purchase. Unlike in previous games, weapons above the player's current level can still be bought, although they cost 3 Sheldon Licenses each instead of 1.

Gold Sheldon Licenses
In addition, there are also Gold Sheldon Licenses that can immediately unlock a weapon regardless of the player's level. Players who import their save data at the beginning of  receive three Gold Sheldon Licenses after completing the first online battle, which is currently the only way to obtain them.

If the player has one, a Gold Sheldon License is spent automatically when purchasing a weapon above the player's level, or when purchasing any weapon with no regular Sheldon Licenses remaining (though in this case, Sheldon will warn the player that it may be a waste of a Gold License).

Gold Sheldon Licenses do not have a counter in the user interface. Instead, Sheldon will tell the player how many they have left after they make a purchase in Ammo Knights.

Trivia

 * One of the hidden squids on the official Splatoon 3 website reveals a tip about the ability to spend extra Sheldon Licenses to purchase weapons above the player's level, but it contains an error: the website states four Sheldon Licenses are required, whereas only three are actually required in-game.
