Tribulation — Difficulty Overhaul

and GitHub Releases.
Visit the website for the full feature
list, config reference, and command guide.

Tribulation is a difficulty overhaul for Minecraft 1.21.1 (Fabric). It
transforms Minecraft's flat difficulty curve into an escalating gauntlet: the
longer you play, the further you explore, and the deeper you dig — the harder
the world fights back. Every system is formula-driven, fully configurable,
and persists across server restarts.

An overhaul, not a content pack. No custom mobs, no new dimensions — vanilla mobs,
vanilla mechanics, sharpened. Zero external dependencies beyond Fabric API.

At a glance

• Minecraft 1.21.1, Fabric loader (0.16.10+), Fabric API required.
• Required on the server; install client-side too for the level badge HUD.
• Every system is individually toggleable through Mod Menu / Cloth Config
  or config/tribulation.json — hot-reload with /tribulation reload.
• MIT licensed.

Features

Four-Axis Mob Scaling

Mob stats are computed from four independent factors the moment a mob
spawns:

All four axes stack. On top of them, flat level offsets tied to where a
mob spawns lift both its stats and its ability tier: a per-dimension offset
keeps the Nether (+25) and End (+40) scarier than the late-game Overworld,
per-biome offsets single out hostile ground (the Deep Dark is +30 by default),
and per-structure danger zones turn landmark raids into a real gauntlet —
ancient cities +30, end cities +25, nether fortresses and bastions +20, ocean
monuments and trial chambers +15. Every offset is configurable and understands
biome and structure tags, so modded content slots in. 21 vanilla mob types have
individually tuned scaling rates and caps — zombies don't scale the same as
skeletons or creepers. Modded hostile mobs are automatically supported with
conservative fallback scaling (configurable per-namespace or per-entity).

In multiplayer, choose which player level drives a nearby mob — the
nearest, the average, or the maximum of the players in range. An
optional group health bonus (off by default) adds +20% mob health for
each extra player nearby, capped at +100%, so the crowd that ganks a mob
doesn't also trivialize it. It touches health only — grouping up never inflates
the XP those mobs drop.

Tier-Gated Mob Abilities

At 5 level thresholds (50/100/150/200/250), mobs unlock new behaviors that
change how you fight them:

• Tier 1 (50) — Zombies call reinforcements, creepers fuse in 0.75s,
  hoglins shrug off knockback
• Tier 2 (100) — Skeletons trade bows for swords, spiders snare you in
  webs, drowned carry tridents, piglins pick up crossbows
• Tier 3 (150) — Zombies break doors, spiders trample crops, wither
  skeletons sprint, zoglins walk through fire
• Tier 4 (200) — Skeleton arrows burn, husks inflict Hunger II,
  vindicators resist damage, wither skeleton blades gain Fire Aspect
• Tier 5 (250) — Zombies sprint, 25% of creepers spawn charged, spiders
  leap, zombified piglins aggro from far away

Every individual ability can be toggled in the config.

Elite Champions

Once you pass level 50, roughly 5% of hostile mobs spawn as Elite
Champions — nameplated minibosses that carry one or two random affixes on
top of their normal scaling. A champion has 1.5× health and 1.25× damage, drops
3× the XP and an extra loot roll, and never appears on a boss. The five
affixes each change the fight:

• Vampiric — heals for half the damage it deals
• Explosive — detonates on death, without scarring the terrain
• Repulsing — a knockback aura keeps you at arm's length
• Thorns — reflects 30% of the damage you land
• Regenerating — steadily heals itself unless you keep the pressure on

Every affix, the spawn chance, and the level gate are configurable.

Blood Moon

Every full-moon night in the Overworld has a 25% chance to rise blood red.
While a Blood Moon burns, the moon-phase scaling axis triples, hostile spawn
caps double, and you can't sleep through it — the sky, fog, and moon tint
crimson with a warning sting so you know what you are in for. It lifts at dawn
and survives a server restart mid-night. Operators can force one on or off with
/tribulation bloodmoon.

Pack Tactics

At tier 3 and above, mobs stop fighting as individuals. Strike a zombie,
skeleton, or spider and every mob of its kind within 16 blocks that can see
the fight turns on you — no more picking off a horde one at a time. Eligible
mobs also spawn in larger groups. Which mobs coordinate, the alert radius,
and the group-size bonus are all configurable.

Environmental Pressure (opt-in)

For players who want the world itself to press back, an optional layer adds two
escalating effects, off by default:

• Debilitating Strikes (tier 3+) — a hit from a scaled hostile saps your
  strength, applying Weakness, and optionally Slowness.
• Oppressive Nights (tier 4+) — high-tier night hostiles track you from
  farther away, and the dark itself closes in a little tighter around you.

Tier-Driven Equipment

Mobs spawn with armor and weapons that scale with their tier — leather and
gold at low tiers shifting toward iron, diamond, and netherite at the top,
with tier-capped Protection/Sharpness/Power enchantments. A clear threat
signal before you even engage.

Special Zombie Variants

Zombie-family mobs (Zombie, Husk, Drowned, Zombified Piglin) can roll one of
two variants on top of normal scaling:

• Big Zombie (10%) — 1.3× size, +10 health, +2 damage, 0.7× speed. A
  lumbering tank.
• Speed Zombie (10%) — 1.3× movement speed, −10 health. Closes gaps fast.

Special Skeleton Variants

Skeleton-family mobs (Skeleton, Stray, Bogged) can roll one of two variants on
top of normal scaling:

• Deadeye Skeleton (10%) — faster bow draw, −10 health. A glass-cannon
  archer.
• Brute Skeleton (10%) — +10 health, 0.5 knockback resistance, 1.3× size,
  slower bow draw. A heavy, hard-to-stagger archer.

Boss Scaling

The Ender Dragon, Wither, Elder Guardian, and anything tagged c:bosses scale
with a separate, gentler formula — health and damage only, capped at +300%. No
sudden one-shots; endgame bosses just stay relevant.

Raid & Patrol Scaling

Vanilla's own escalation system scales with you, driven by the tier of the
targeted players — while bells, Hero of the Village, and the raid bar all
behave normally.

• Bigger patrols — a pillager patrol captain adds extra members as your
  tier climbs, each spawned through the normal scaling path with
  tier-appropriate stats, armor, and weapons.
• Extra raid waves — raids targeting high-tier players run additional
  waves on top of the vanilla count.

Death Penalty Systems

All penalties are independently toggleable. Mix and match the stakes you
want:

• Death Relief — lose 2 levels on death (rubber-band mechanic,
  cooldown-gated)
• Shatter Shards — rare drops (0.5%) that lower your level by 5, at the
  cost of 10s of Slowness, Mining Fatigue, and Weakness
• Hardcore Hearts (opt-in) — permanently lose max health per death;
  restore with craftable Heart Fragments
• Soul Inventory (opt-in) — items are destroyed on death unless they
  carry the Soulbound enchantment, or any enchantment tagged #c:soulbound, so
  protections from other mods count too

A popped Totem of Undying can optionally interact with these penalties via
the totems config: have a totem pop still apply the Death Relief level loss
(countsAsDeathRelief), or shield you from the Hardcore Hearts loss
(protectsHearts).

Ascendant Shard

The counterweight to the death penalties: a crafted item — four Shatter Shards
around a Nether Star — that raises your difficulty level by 25 on use, a way
to court harder mobs and their richer rewards on your own terms instead of
waiting out the clock. It stops at the level cap and, by default, costs you
nothing to use.

Offline Level Decay (opt-in)

An optional catch-up mechanic for long breaks, off by default. After a grace
period away from the server (7 days by default), your level slowly slips — 2
levels per day gone — so a returning player meets a difficulty that matches
their rust, never dropping below a configurable floor.

Rewards Scale Too

• Bonus XP — scaled mobs drop up to 2× base XP, proportional to their
  scaling factor
• Extra loot (opt-in) — a chance to duplicate a drop, scaling with mob
  difficulty

Level Badge HUD

A compact, icon-only badge shows your current tier at a glance — tinted
white through yellow, orange, and red to dark crimson across tiers, with a
thin progress bar toward your next level. Flashes gold on level-up. Anchor
to any screen corner; stacks cleanly with HUDs from the other Concord suite
mods.

Difficulty Statistics

Eight custom statistics track your difficulty milestones — highest level
reached, levels lost to death relief, levels lost to offline decay, Shatter
Shards used, Ascendant Shards used, half-hearts lost, half-hearts restored, and
Tier-5 mobs killed. They live alongside vanilla's counters in the Statistics
→ Custom screen, so progress persists across sessions.

Commands

Player commands: /tribulation info, /tribulation hearts. Operator
commands cover level set/reset, hot-reload, forcing a Blood Moon on or off
(/tribulation bloodmoon), and the debug/inspect scaling-breakdown tools.

Optional integrations

Tribulation detects and integrates with these mods when present. None are
bundled — install whichever you already use.

• Mod Menu — config screen entry
• Cloth Config — settings GUI
• Jade / WTHIT
  — mob scaling tooltip overlays
• EMI / REI /
  JEI — Heart Fragment and
  Ascendant Shard recipes

For mod developers: a stable, read-only API
(com.rfizzle.tribulation.api) exposes player level/tier, mob scaling
state, and a level-change event — see the
developer docs.
