Highly Configurable

startingFactor: Overall baseline multiplier (1.0 = vanilla stats, 2.0 = double stats).
startingDistance / startingTime: The delay (in blocks or minutes) before the difficulty begins to scale.
increasingDistance: Blocks needed to increase strength by the distanceFactor (e.g., 300 blocks = +10% stats).
increasingTime: Minutes needed to increase strength by the timeFactor (e.g., 60 mins = +5% stats).
heightDistance: Blocks above/below startingHeight needed to increase strength by the heightFactor.
maxFactorHealth / Damage / Protection: The absolute maximum multiplier allowed (e.g., 2.0 = max double stats).
maxFactorSpeed: Max speed multiplier (Applies only to Special Speedy Zombies).
allowRandomValues: Enables randomized stat variations on spawn.
randomChance / randomFactor: The % chance for a mob to mutate, and the maximum % variance of those stats.
extraXP: Dynamically calculates bonus XP drops based on the mob's active strength multiplier.
maxXPFactor: The maximum allowed multiplier for XP drops (e.g., 2.0 = double XP max).
