The "Sell" button has been made more prominent than before. Skill activation timing has been added. Currently, there are three types of skill activation timing: 1.At the start of the battle: The skill activates when the battle begins and its effect disappears when the battle ends. 2.Added to the card: For status-boosting skills, the effect is already embedded within the card. 3.On the player's action: During the battle, the skill has a chance to activate each time the player takes an action.
