World Threat – Progressive Difficulty (Experimental)

Experimental datapack
World Threat – Progressive Difficulty 
World Threat is a vanilla-friendly datapack that adds progressive difficulty (0–15). As players progress and the world becomes more “active,” hostile mobs scale up – keeping late-game survival challenging instead of turning into safe farming.

How difficulty is calculated
Global world difficulty:
difficulty = MAX(stage, threatTier)
◈ STAGE: progression stage based on key vanilla advancements (never decreases).
◈ THREAT: global “world threat points” gained from player activity (kills, mining, dimensions, bosses).
◈ threatTier: derived from THREAT (+1 tier per 25 THREAT, max 15).
So difficulty rises either through progression (STAGE) or through high activity (THREAT).

Anti-farm throttle (no sudden spikes)
To prevent mob farms from instantly skyrocketing difficulty:
◈ points are stored in a buffer first,
◈ then transferred into THREAT at a fixed rate:
THREAT increases by at most +1 per second.

Farms can fill the buffer quickly, but difficulty increases smoothly over time.

Mob scaling
All hostile mobs receive moderate, linear scaling by tier:
◈ increased max health, attack damage, armor, and movement speed.

Adds moderate “group flavor” tweaks:
◈ RANGED mobs: longer aggro range + slightly improved weapons at higher tiers
◈ CASTERS: evokers get small late-game survivability/mobility buffs
◈ BRUTES: some knockback resistance in the late game
◈ AGILE: speed boosts for spiders/small mobs/phantoms

Plus a few careful, targeted tweaks for certain mobs (creepers/witches/endermen, etc.) – kept reasonable.

Features
