Augment

Augments (also known as Augment Cards, Augmentation Cards or Augmentations ) are permanent upgrades to a character's stats that can be obtained through Survivor and can be applied in the S.T.A.R. Labs interface accessible in the top right corner of the Collection interface or by tapping "Augment" on a character card's interface.

They come in 5 different types in 3 different intensities. Health, Damage, Crit Chance, Crit Damage, Character XP, and they come in Minor, Medium, and Major intensities, totaling 15 types.

The maximum limit for augmenting critical chance is 50%, while the maximum limit for crit damage is 250%. It is possible for an augment to be partially wasted, as they can still be added if the gap between current value and the cap is smaller than the augment's value. Using health and damage augments, you can augment a card to have a 25% increase to their damage and health.

Augments take an extremely long time to max; expect to spend at least hundreds of Last Laugh tickets to max Health and Damage on a single character. While Crit Chance and Damage augments seem to be rarer, it takes less of them to max so overall it is slightly easier to max those. It may take months of pure game time to fully augment all characters. Regardless, this is the amount of how many cards are need to fully maxed out a character:

_Health/Damage: 38 Major, or 75 Medium or 150 Minor Augment Cards

_Crit Chance: 10 Major, or 17 Medium or 50 Minor Augment Cards

_Crit Damage: 13 Major, or 25 Medium or 50 Minor Agument Cards
