• "War God" is a passive ability that automatically turns all heart-suit cards in Guan Yu’s hand into Attack cards. These cards cannot be used for their original purpose. For example, if a Fire Attack is a heart card, it is treated as a normal Attack.

• "Fighting Soul" is also a passive ability. Whenever Guan Yu is damaged, the player who inflicted the damage must receive a Nightmare Token, even if they are on Guan Yu’s own team.

• When Guan Yu dies, if multiple players have the same number of Nightmare Tokens, Guan Yu can choose who among them flips the judgment card. If the player fails the judgment (the card is anything other than a Peach or Peach Garden), they die immediately. This death cannot be prevented by any means, including Pang Tong’s "Nirvana."

• Judgment manipulation plays a crucial role in "Fighting Soul". Characters like Sima Yi can influence the judgment card flip. Sima Yi can save Guan Yu’s target if he has a Peach or Peach Garden, or he can ensure the target’s death by manipulating the judgment card. Zhang Jiao, however, can only switch the judgment to black cards, which ensures the victim’s death since the only cards that can save the player are red.

• If Guan Yu and the King are the last two characters left in play, and the King kills Guan Yu, "Fighting Soul" does not activate, as the game ends immediately when the King becomes the last player standing.

• "Fighting Soul" still takes effect even if Guan Yu dies. For instance, if Sima Yi is brought to the brink of death, his "Feedback" only activates if he survives. But if Guan Yu is killed, the character who delivered the final blow still gains a Nightmare Token immediately.

• If Guan Yu is chained to another character and deals elemental damage, causing harm to himself, he gains a Nightmare Token.

• "War God" allows Guan Yu to attack any player, regardless of distance. This unlimited attack range makes him a significant threat.

• "Fighting Soul" serves as one of the best deterrents in the game, making players hesitant to damage Guan Yu due to the danger of receiving Nightmare Tokens.

• Guan Yu's defensive strength is bolstered by his five units of health, giving him a strong foundation to stay alive longer in battles.

• "War God" can be a double-edged sword. Many heart-suit cards, such as Peach and Draw Two, are valuable resources, but Guan Yu must treat them as Attacks, limiting his ability to heal or draw cards.

• Fighting Soul is ineffective if Guan Yu is the last character on his team, as the game ends upon his death and the Nightmare Tokens become irrelevant.

• Guan Yu struggles to support allies due to the restrictions of "War God", which often deprives him of healing cards like Peach when needed.

• Sacrificial Teammates:
  Characters like Xun Yu and Diao Chan can force a teammate to damage Guan Yu, shifting the burden of "Fighting Soul" to that teammate. This manipulation can make the enemy hesitate to attack Guan Yu directly.

• Immunity to Fighting Soul:
  Zhang Chunhua is an ideal opponent for Guan Yu due to her "Unfeeling" ability, which makes her immune to the effects of "Fighting Soul", negating Guan Yu's primary defensive mechanic.

• Disarming Guan Yu:
  Cai Wen Ji can counter Guan Yu’s Fighting Soul with her "Heartbroken" ability, removing the threat of Nightmare Tokens from the board if she dies, effectively neutralizing the threat of Guan Yu’s retaliation.

• Manipulating Damage:
  Xiao Qiao poses a dangerous challenge for Guan Yu, as she can transfer damage to him. While this can be advantageous in some situations by forcing enemies to gain Nightmare Tokens, it can also backfire if she causes Guan Yu’s allies—or even Guan Yu himself—to receive Nightmare Tokens.

King

• • Guan Yu is a poor King choice. "Fighting Soul" is irrelevant because the game ends immediately if the King dies. Moreover, "War God" often forces him to use hearts for Attacks, limiting his access to healing cards like Peach.

Loyalist

• • As a Loyalist, Guan Yu has some potential. "War God" enables him to consistently attack Rebels, regardless of range, and Fighting Soul makes him a tough target. However, the restriction on Peach cards can make it harder for him to protect the King when needed.

Rebel

• • Guan Yu excels in the Rebel role. "War God" allows him to attack the King without distance limitations, and "Fighting Soul" creates a dilemma for the King and Loyalists—they need to eliminate him to win, but damaging him comes with a serious risk.

Spy

• • Guan Yu is a solid Spy due to his strong deterrents and high health. However, he must carefully ensure that the Loyalists are taken out before the last Rebel falls, as his "Fighting Soul" loses effectiveness if he is the last character standing.

Guan Yu is a powerful character but can feel limiting to play due to "War God" turning valuable cards into Attacks. While "Fighting Soul" serves as a strong deterrent, it can become ineffective if Guan Yu is the last member of his team to die. His role in the game is heavily defensive, and players must navigate the restrictions of "War God" while exploiting the threat of "Fighting Soul" to keep him alive.

Guan Yu’s tragic end came after his capture by the forces of Sun Quan. After being executed, his death sent shockwaves throughout the Three Kingdoms. Guan Yu’s execution secured Wu’s control over Jingzhou, a key strategic region. However, the consequences of Guan Yu’s death extended beyond mere territorial gains.

Guan Yu’s death led to a series of eerie events, most notably the supernatural revenge that is tied to his spirit in the novel. During a celebratory feast honoring Lu Meng’s victory, Sun Quan toasted his general’s success, only for Lu Meng to suddenly become possessed by Guan Yu’s spirit. As the ghost of Guan Yu took control, Lu Meng cursed Sun Quan and called him a “purple-bearded rat.” Guan Yu’s spirit, speaking through Lu Meng, vowed to seek revenge for his death. As the possession took hold, Lu Meng died on the spot, his body bleeding from its face.

Fearing Guan Yu’s vengeful spirit, Sun Quan grew paranoid and sought a way to deflect the consequences of Guan Yu’s death. His advisor Zhang Zhao suggested that Sun Quan send Guan Yu’s severed head to Cao Cao, making it appear that Wei was responsible for Guan Yu’s death. The plan was to divert Liu Bei’s wrath toward Wei instead of Wu. Sun Quan took the advice and sent Guan Yu’s head to Cao Cao, but this did not stop the rumors of Guan Yu’s vengeance.

Cao Cao himself was deeply disturbed when he received the severed head of Guan Yu. The legend tells that when Cao Cao opened the box and saw Guan Yu’s face, it remained unchanged from when he was alive, and the head even opened its eyes and moved its beard, sending Cao Cao into a panic. Fearing the curse of Guan Yu’s spirit, Cao Cao ordered the creation of an effigy to give Guan Yu a proper burial, hoping to appease his restless soul.

Guan Yu’s death and the events that followed illustrate his imposing presence both in life and death. This story of vengeance and fear links directly to his Fighting Soul ability in Sanguosha, where his spirit continues to torment those who bring about his downfall.
