• "Roar" is Zhang Fei's ability, which allows him to use Attack as many times as he wants during his turn without restriction.

• "Fighting Saint" is Guan Yu's ability, allowing him to use any red card as an Attack.

• Guan Xing and Zhang Bao cannot use "Paternal Souls" if they are under the effects of Starvation.

• The effects of "Paternal Souls" only last for the turn that the ability is activated. They cannot use "Fighting Saint" outside of their turn, even if they successfully activate "Paternal Souls."

• The two cards flipped over by "Paternal Souls" are not judgment cards and cannot be manipulated by judgment-altering abilities.

• Guan Xing and Zhang Bao become very aggressive and dangerous when "Paternal Souls" activates, with the ability to deal massive damage during their turn.

• Players enjoy using Guan Xing and Zhang Bao because of the potential for explosive turns and powerful attacks.

• After successfully activating "Paternal Souls," they often exhaust their resources, making it difficult to recover and use the ability again.

• There is no guarantee that "Paternal Souls" will activate when needed. The two cards flipped must be of different colors, which can introduce inconsistency into their strategy.

• When they use "Paternal Souls," all players can see the cards drawn. For example, if they reveal no Escapes, opponents may become more aggressive and take advantage of their vulnerability.

• Supportive Card Providers:
  Characters like Liu Bei, Guo Jia, Xu Shu, and Chen Gong can supply Guan Xing and Zhang Bao with additional cards. This helps prepare for their "Paternal Souls" activation by providing more options in hand.

• Refill Abilities:
  Xun Yu can replenish Guan Xing and Zhang Bao’s hand, allowing them to attack him during their turn when "Paternal Souls" is active and immediately regain cards.

• Retaliatory Abilities:
  Characters such as Xiahou Dun, Fa Zheng, Sima Yi, and Cai Wenji have retaliatory abilities that activate per instance of damage, making it risky for Guan Xing and Zhang Bao to attack multiple times during their turn.

• Lockout Protection:
  Chen Gong can protect himself from Guan Xing and Zhang Bao’s multiple attacks by preventing damage through his ability, creating a defensive wall.

King

• • Guan Xing and Zhang Bao make a poor choice for the King role due to their inconsistency and reliance on situational ability activation.

Loyalist

• • As loyalists, they can be effective if timed well, using "Paternal Souls" to quickly dispatch a Rebel when the opportunity arises.

Rebel

• • They perform well as rebels, able to focus their powerful attacks on the King and deal significant damage when their ability is active.

Spy

• • They are not ideal spies, as their ability does not lend itself well to survival or subterfuge, and it cannot be consistently activated to keep them alive for the long term.

Guan Xing and Zhang Bao are an exciting and powerful duo, but their ability lacks originality, as it directly copies the abilities of their fathers. Despite this, they remain a fun choice to play, especially when the timing is right for a big attack. It is crucial to activate "Paternal Souls" when ready to unleash multiple attacks, but if the ability fails early in the game, it is often better to remain patient rather than reveal your hand too soon. Accept that you may only be able to use "Paternal Souls" once in a game, similar to Huang Gai's aggressive but limited approach.

Guan Xing and Zhang Bao were prominent figures in Romance of the Three Kingdoms, each carrying the legacy of their famous fathers, Guan Yu and Zhang Fei. Just before the Battle of Yiling, the two sons initially compete for leadership of the vanguard force. However, Liu Bei intervenes and binds them as oath brothers, mirroring the famous oath their fathers made years earlier. This event marks the beginning of their deep bond and shared loyalty to the Shu cause.

Guan Xing’s most notable achievement in the novel comes when he avenges his father by slaying Pan Zhang, the general who had captured Guan Yu. He then retrieves his father’s legendary weapon, the Green Dragon Blade. Later, Guan Xing continues his service under Zhuge Liang, leading Shu forces in the Northern Expeditions against Wei until his death from illness.

Zhang Bao similarly plays a significant role in Shu’s military campaigns. He fights alongside Guan Xing, including during Zhuge Liang’s Northern Expeditions. Tragically, Zhang Bao meets an early demise in the third Northern Expedition when he falls into a gully while pursuing Wei generals and succumbs to his injuries. His death is so devastating that Zhuge Liang, upon hearing the news, faints from grief.

In Sanguosha, their shared ability "Paternal Souls" reflects their connection to their fathers' martial prowess, with Guan Xing’s "Fighting Saint" channeling Guan Yu’s precision and Zhang Bao’s "Roar" embodying Zhang Fei’s fierce attacks. Their bond in the game mirrors their relationship in the novel, where they grow from rivals to sworn brothers, united in their quest to honor their fathers' legacies.
