Features

Everything Tribulation does to make your world progressively more dangerous.

Scaling Axes

Mob stats are boosted by three independent axes that combine multiplicatively per attribute. Each axis produces a factor that gets added to the mob's base stat via attribute modifiers.

Time (Player Level)

Your playtime accumulates ticks (default: 72,000 ticks = 1 hour per level). Max level is 250. Every mob spawned near you uses your level to compute a time factor per stat: min(level * rate, cap).

Distance from Spawn

Beyond startingDistance (default: 1000 blocks), every 300 blocks adds 0.1 to the position bonus. Caps at 1.5. Only applies to health, damage, armor, and toughness.

Height (Y-Level)

Deviation from Y=62 by 30 blocks adds 0.1. Supports both positive and negative height scaling. Caps at 0.5.

Distance and height are optionally excluded in non-Overworld dimensions. Time scaling applies everywhere.

Scaled Mob Types

21 vanilla hostile mobs have individually tuned scaling rates and caps for six attributes. Each mob can be toggled on or off independently.

Rate = stat gain per player level. Cap = maximum total factor from the time axis alone. Follow range and toughness are also scaled per-mob (see config for full values).

Tier-Gated Abilities

At five tier thresholds, mobs unlock special behaviors beyond raw stat boosts. Each ability can be individually toggled.

Tier Level Abilities Unlocked
Tier 1 50 Zombie reinforcements, Creeper shorter fuse, Hoglin knockback resistance
Tier 2 100 Skeleton sword switch, Spider/Cave Spider web placing, Drowned trident upgrade, Piglin crossbow
Tier 3 150 Zombie door-breaking, Spider crop trampling, Wither Skeleton sprint, Zoglin fire resistance
Tier 4 200 Skeleton flame arrows, Husk Hunger II, Wither Skeleton fire aspect, Vindicator damage resistance
Tier 5 250 Zombie sprinting, Creeper charged chance (25%), Spider leap attack, Zombified Piglin aggro range

Zombie Variants

Zombies have a chance to spawn as special variants with distinct visual and mechanical differences.

Big Zombie

10% chance. Scaled up 1.3x in size with +10 bonus health and +2 bonus damage, but 0.7x movement speed. A lumbering tank.

Speed Zombie

10% chance. 1.3x movement speed but -10 health. Fast and fragile — ambush predator behavior.

Boss Scaling

Boss mobs (Ender Dragon, Wither, Elder Guardian, and any entity in the c:bosses tag) use a separate, gentler scaling formula.

Formula

Time factor: level * bossTimeFactor / maxLevel. Distance uses bossDistanceFactor. Height scaling is skipped entirely for bosses.

Defaults

Max factor: 3.0x. Time rate: 0.3. Distance rate: 0.1. Combined factor capped at bossMaxFactor. Works in all dimensions.

Death Relief

When you die, your player level decreases by 2 (configurable). This provides a natural difficulty rubber-band: dying frequently keeps your level in check, while surviving pushes the ceiling higher.

Shatter Shards

Rare item drops from scaled mobs that let you intentionally lower your difficulty level.

Hardcore Hearts Opt-in

Disabled by default. When enabled, each death permanently reduces your maximum health.

Soul Inventory Opt-in

Disabled by default. When enabled, your inventory is destroyed on death unless items carry the Soulbound enchantment.

Modded Mob Support

Tribulation automatically scales any modded mob that extends Monster (hostile mob base class).

Extra XP & Loot

Scaled mobs reward more experience to compensate for their increased difficulty.

Global Stat Caps

Hard ceilings on the total factor applied to each attribute, preventing infinite scaling regardless of axis combination:

Attribute Default Cap Description
Health4.0xMaximum health multiplier from all axes combined
Damage4.5xMaximum damage multiplier
Speed0.5xMaximum speed bonus (additive to base)
Armor2.0xMaximum armor value multiplier
Follow Range1.5xMaximum detection range multiplier
