I'm not sure specifically which 'best cloak and dagger graphic novel' you mean. But usually, there would be a spy - like character, someone who is good at sneaking around and uncovering secrets.
A party with a Cleric, a Rogue, and a Wizard can be great for the story in BG3. The Cleric can heal and provide support, the Rogue for sneaking and lockpicking, and the Wizard for powerful magic to deal with various challenges in the story.
Lae'zel has a fascinating story too. Being a Githyanki warrior, her loyalty to her people, her beliefs about the creche and her experiences that make her question and grow throughout the game add depth to her story.
In BG3, Lae'zel has an amazing character story. Her journey from a loyal Githyanki warrior to one who questions her people's ways is captivating. She has to deal with her loyalty to Vlaakith while also seeing the different ways of the world outside her own culture.
One of the best companion stories is that of Astarion. His backstory of being a vampire spawn and his journey to break free from Cazador's control is both tragic and engaging. It unfolds as you progress in the game, revealing more about his past and his hopes for the future.
Astarion is a great choice. His complex backstory adds depth to the story. He's a vampire spawn with his own motives and development throughout the game. Another good one is Shadowheart. Her mysterious past and her role within the Sharran cult bring interesting story elements. And Gale, his connection to the weave and his pursuit of magic in a rather dangerous way enriches the overall story experience.
The Cleric class also has a strong case for being a great class for the story. Clerics are tied to their deities, and this connection can drive the story forward. Their religious beliefs and the quests related to their faith can create some really engaging storylines. For example, they might have to perform certain rituals or seek out sacred artifacts, which are all integral parts of the overall story.
Gale is another good one. His story is filled with magic and mystery. His relationship with the Weave and his past mistakes make him a very interesting character to have around during the story. He often provides insights into the magical elements of the game world, which can enhance the overall story experience.
The Tieflings are also an excellent race for the story. They are often outcasts, and their struggle for acceptance and place in the world adds a lot of depth to the overall narrative. There are many quests and storylines related to the Tieflings that can make your playthrough very engaging.
Gale's story is also among the best. His relationship with the magic he wields and the danger it poses due to the Netherese orb in his chest is a central part of his story. He has to make difficult choices about his power and his future. Lae'zel's story stands out as well. Her devotion to the Githyanki cause and her subsequent experiences that make her question her beliefs add depth to her character.
