Skill Space: Initially, each dark hero will have a skill space, which is expected to increase according to the game version. Free installation and disassembly: Players can install skills into Dark Heroes at will when they are not in combat, or they can take them out for use by other Dark Heroes, so that players can draw the most suitable and strongest combat strategy in various fierce battles. Skill validity period: When a player acquires a skill, the skill will start a 7-day (168 hours) countdown. Before the countdown ends, the character equipped with the skill can activate the skill unlimited times under the conditions. When the countdown is over, the skill will be automatically removed from the character and the backpack will be recovered In the future territory system, those temporarily disabled skills will have unique and unexpected effects. --- # Agent Instructions This documentation is published with GitBook.
