In the advanced challenge of Star Trace Resonance, the Star Trace Resonance Cardmani Trial serves as the core content of a high-difficulty team dungeon, testing players' skills and cooperation. This trial, with Soul Controller Maximus as the final boss, is located deep within the Eternal Night Canyon's Abyssal Altar, where three shattered soul blades float at the entrance. The dungeon is filled with floating purple soul flames and fractured rune stones, and players must face challenges such as soul splitting, gravity traps, and flame slashes. For the first attempt, it is recommended to form a balanced team consisting of 1 tank, 2 damage dealers, and 1 healer.

Upon entering the dungeon, the first task is to clear four waves of soul minions. These translucent enemies will release chained soul explosions, so priority should be given to focusing fire on the elite monsters marked with a purple light. In the second area, on the floating platform, Maximus will use his first core skill, Soul Split, attacking all players with a soul stripping attack that causes damage and generates soul remnants on the ground. At this point, players must immediately spread out to ensure that each person's remnant is spaced apart; otherwise, overlapping soul explosions can cause instant-kill level damage. The tank should quickly pull the boss to the edge of the arena to create a safe space for teammates to deal damage.

The third phase, Earthsplit Slash, tests individual reaction times. Maximus will randomly target a player to unleash a fan-shaped flame slash. The targeted player must immediately move to an open area of the field to avoid hitting teammates. During this time, the ranged damage dealers in the team should take advantage of the 3-second stun period after the boss uses its skill to focus fire on the soul core on its back.

In the final phase, Maximus will summon three soul weapons, which players must destroy simultaneously within 90 seconds. It is crucial not to focus on a single weapon, as a difference of more than 20% in remaining health between any two weapons will trigger a regeneration mechanism. It is suggested to assign the main damage dealer to handle two weapons, while the secondary damage dealer and healer work together on the third, with the tank drawing the boss's aggro throughout. Once all weapons are destroyed, the entire team gains a 30-second Soul Resonance state, during which attacks on the boss deal double damage. Players should utilize this mechanic effectively during the challenge.

To successfully complete the Star Trace Resonance Cardmani Trial, everyone needs to understand the boss's mechanics and adapt according to the situation, thus keeping themselves in an unbeatable position. Especially when you are in the Soul Rift, pay attention to your positioning to avoid being hit by the boss's skills. Additionally, close cooperation with teammates and timing your attacks appropriately are key to defeating the boss and winning the challenge.
