A classic and effective party composition could be a tank, a healer, a ranged damage dealer, and a melee damage dealer. For example, a Fighter as the tank to soak up damage, a Cleric for healing, a Ranger for ranged attacks, and a Rogue for melee damage and sneaking around. This allows for a balanced approach in combat and different skills to be utilized during the story quests.
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.
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.
For story, I'd recommend Shadowheart. Her loyalty to Shar and the slow reveal of her true self as the story progresses is fascinating. Then there's Astarion. His journey from being a subservient vampire spawn to potentially finding freedom is a great story arc. Karlach is also a good pick. Her bubbly personality combined with her tragic backstory of being in Avernus makes for a very engaging story element in the party.
A composition with a Ranger, a Cleric, a Monk, and a Warlock. The Ranger can be a ranged attacker and tracker, good for exploring and dealing damage from afar. The Cleric is essential for healing and also has some buffs and debuffs. The Monk is a unique melee combatant with high mobility and unarmed attacks. The Warlock has some interesting spellcasting abilities and can make pacts for different powers, which adds a lot of variety to the party's capabilities in the story.
The best party for BG3's story could be a Barbarian, a Druid, and a Monk. The Barbarian is great for raw combat power and can soak up damage. The Druid can transform and has a variety of spells for different scenarios. The Monk is fast and has unique combat abilities that can help in battles throughout the story.
The tiefling origin story is often rooted in the idea of a fiendish or infernal bloodline. They are typically descendants of humans who made pacts with devils or other powerful fiends in the distant past. This connection to the infernal gives them their distinct features like horns, tails, and strange eyes.
One common Tiefling back story could be that they are descendants of humans who made pacts with devils long ago. Their infernal heritage has led to their unique appearance and often a life of being shunned in some societies. They might struggle to find acceptance due to the fear others have of their devil - like features.
A Tiefling Warlock could have a back story like this: A young Tiefling was outcast from his community due to his fiendish heritage. While wandering alone in the wilderness, he stumbled upon an ancient, dark tome. As he opened it, a powerful, otherworldly entity made contact. This entity promised the Tiefling power in exchange for his loyalty. Desperate for a sense of purpose and power to overcome his outcast status, the Tiefling agreed and thus became a Warlock, with his newfound powers fueling his journey to prove himself and perhaps one day, return to his community on his own terms.
Perhaps 'Abyssal Descendant' can be used as another name for tiefling in a story. Tieflings are often thought to have some sort of connection to the Abyss, a place of chaos and demons in many fictional universes. By calling them 'Abyssal Descendant', it not only implies their otherworldly origin but also adds an air of mystery and danger to the characters. This name can be useful when you want to create a more menacing or exotic image for the tieflings in your story.
