In Castlevania II: Simon's Quest, you play exclusively as Simon Belmont. There are no other playable characters or traditional 'builds' in the RPG sense. However, Simon's effectiveness in combat and exploration is heavily influenced by the equipment he acquires and the strategic choices you make regarding upgrades and item usage. This section focuses on optimizing Simon's capabilities through equipment and understanding his progression.
Simon's progression is primarily tied to his equipment (whips, shields, sub-weapons) and his experience level, which directly impacts his maximum HP. There are no skill trees or stat allocations. Therefore, a 'build' in this context refers to the optimal combination of items and a strategy for acquiring them.
