What is Stress
A Status that Accumulates During Combat

Stress accumulates at the end of the turn or when taking damage. When Stress is fully accumulated, the Combatant will enter a Collapse state and suffer various disadvantages.
Can be Managed with Healing or Shield

By using Healing Cards, you can recover not only HP but also recover from Stress. Additionally, if damage is prevented with a Shield, Stress will not increase.
Collapse and How to Remove It
Cards and Ego Skills Become Unusable

A Combatant who has fallen into a Collapse state will have their Ego Skill become unusable, and their Cards will change into unusable Break Cards. Additionally, their Max HP will be greatly reduced, and further recovery will be impossible.
Recovery is Possible by Using Break Cards

A Collapsed Combatant recovers by using a specified number of Break Cards. The first time requires 5 Cards, and for each subsequent Collapse, you'll need to use +1 more Break Cards to recover. When recovering from Collapse, the Ego Skill's Cost will also be greatly reduced.
