There isn’t a true "max level" in Skull and Bones in the traditional sense of reaching a specific number and stopping progression. However, the concept of "Kingpin" has two relevant interpretations:
1. Kingpin as Infamy Rank:
Reaching Kingpin is the highest rank in the Infamy system, signifying you’ve become the most notorious pirate.
Progression continues beyond Kingpin: After reaching this top rank, your Infamy level continues to increase numerically. This number serves as a continuous indicator of your dominance and mastery in the game.
2. Specific Enemies:
"Kingpin" also refers to specific powerful enemy pirates you encounter throughout the game. Defeating these Kingpins is crucial for progressing the narrative and gaining significant rewards.
Therefore, while there’s no single "max level" to achieve, becoming a Kingpin (rank) and defeating all Kingpin enemies represent the highest accomplishments in the game. Beyond that, your Infamy level continues to rise, showcasing your ongoing progress and dominance in the world of Skull and Bones.
