Changelog

1.0.0

• Initial release.
• Serpent spawn chance scales with the number of bosses defeated (global keys).
• Reads vanilla spawn chance at runtime and keeps every vanilla spawn condition (night, rain/thunderstorm, interval, max spawned).
• Defaults set to the maximum: BonusPerBoss = 5, MaxChance = 100% (reaches 100% after 4 bosses).
• Configurable bonus per boss, max chance cap, base chance override, boss key list and affected prefabs.
• Automatic recalculation when progression changes; restores vanilla values on world exit.
