About Idle Calibur: Zero
Idle Calibur: Zero combines TRPG, SLG, idle, roguelike and gacha elements in an anime-style fantasy world. You gather strength, uncover hidden truths and challenge destiny on a journey toward kingship. Character builds draw on a tabletop role-playing-inspired system, letting you assemble different powers and shape your character in varied ways; outcomes depend on your abilities as well as the roll of the dice.
Tactical battles
Combat uses a turn-based tactical system with reactive and additional actions, timing mechanics and action management. Some encounters also offer interactive actions tied to particular enemies or situations:
- Dialogue: talk with sentient adversaries to potentially end a fight peacefully or recruit them as allies.
- Tail severing: disable an enemy's formidable appendage.
- Mirrored reflection: turn an enemy's petrifying gaze against them, potentially causing them to petrify themselves.
- Knowledge and chanting: discover a demon's true name and use it to weaken or defeat the demon.
Other combat systems include debate warfare, where you manage counterarguments and social skill checks, and military combat, where you raise armies and maintain their morale through training and attention outside the battlefield.
Relationships and growth
You can spend time with loved ones and companions, take on side quests, learn more about them and strengthen your bonds. These relationships also contribute to personal growth.
Gradual development
The game includes incremental development and time-management mechanics. Some systems call for a slower pace, giving you time to explore them gradually.
