The Crimson Reaper
10,000 HP boss with three health-based phases, escalating on-attack debuffs, and a Bleeding Heart phase that triggers once he drops below half health.
The Crimson Reaper is a single boss fought at 10,000 HP over three phases. Each melee hit ramps his damage from 20 up to 40 through a four-hit combo counter, and 60% of hits also trigger a special effect from a rotating pool. He summons minions to buff his own max health, heals himself by consuming a minion when he drops under 80% HP, and pastes his arena on spawn with a FAWE schematic. The arena undoes itself when he dies or despawns.
Spawn Command
/mm egg get CRIMSON_REAPER
The arena pastes through FAWE the moment the Reaper is summoned. Make sure FAWE is installed and the spawn area is clear before running the command.
Phase Breakdown
Spawn until damage drops him under 60% HP
On spawn he sets Phase 1 stats (12 attack, 4 wound tick, short shadow bind). He opens with a Crimson Minion summon ring, then a small Phase 1 rotation. Every ~5 seconds he rolls one of two skills. Melee attacks stack a combo counter that adds 5 damage per stack up to 4 stacks, and 60% of hits also roll an extra effect.
- Blood Curse Aura. 10-block aura on nearby players, curse ticks and particle rings for 20 seconds
- Summon Fighter Minions. Extra THE_CRIMSON_FIGHTER adds, capped at 6 within 50 blocks
- On-hit specials. Crimson Wound (bleed DOT), Blood Mark (marked players heal the boss when hit), and a rare Crimson Strike normal variant
26% to 60% HP
Once he takes enough damage to sit inside the 26-60% health band, Phase 2 stats kick in (15 attack, 5 wound tick, longer shadow bind, arena paste 2). The random pool widens to five skills, and Shadow Bind unlocks on the on-attack special roll.
- Blood Curse Aura, Summon Fighter Minions (from Phase 1)
- Blood Pool Totem. A ring of up to 13 blood totem dummies spawns 5 to 12 blocks around him, each pulsing damage and exploding at end
- Vampiric Leash. A pull-aura on a random nearby player. Stay within 12 blocks and it just ticks. Break out of range and it hits you with damage and Weakness
- Blood Rain. Blood meteors rain across a 20-block area for 5 seconds
- Shadow Bind added to the on-hit special pool. Slowness II and Weakness I on target
Under 25% HP
At 25% he sets Phase 3 stats (20 attack, 8 wound tick, arena paste 3). The random pool gains Pulse Lock as a sixth entry, and the Crimson Strike execution on the on-hit special pool becomes usable. Below 30% HP it becomes an EXECUTION damage skill that one-shots for 999 damage.
- Blood Curse Aura, Blood Pool Totem, Summon Fighter Minions, Vampiric Leash, Blood Rain (from Phase 2)
- Pulse Lock. Picks one random player within 25 blocks, spawns a Blood Source dummy 5 to 10 blocks away, and locks them with a 30-second Pulse Lock aura. Destroy the dummy to break the lock early
- Crimson Strike execution on-hit special. Below 30% target HP, one-shots the target for 999 damage. Above 30% it just becomes a heavy knockback strike
Triggered on damage once below 50% HP, 20% chance
When his HP drops between 1% and 50%, every hit has a 20% chance to trigger the Bleeding Heart Void. He teleports back to spawn plus 8 blocks in the air, becomes damage-immune, and stuns himself in place. A Bleeding Heart dummy is summoned near his spawn, which pulls players within 8 blocks toward it, damages anyone within 4 blocks, and spawns waves of THE_CRIMSON_FIGHTER minions. Kill every minion in a 50-block radius to break the heart. Fail to clear them before the timer ends and the heart explodes with a huge knockback, damage, Blindness, Wither, and ignite in a 16-block radius.
Triggered on damage below 5% HP, once per fight
At 5% he heals to full, gains Regeneration X and Resistance X, gets a light Wither I of his own, removes all minions, and cancels/deflects all incoming damage. He then plays out an eight-phase scripted cinematic (message + disguise + AoE damage each phase), ending with a "Crimson Apocalypse" three-wave AoE.
Key Mechanics
Progressive combo
Melee hits build a 4-stack combo counter. Damage is 20 + (stack * 5), so a full 4-stack hit deals 40. The counter resets 3 seconds after his last swing.
On-hit specials
60% of melee attacks also roll a special: Crimson Wound (bleed DOT), Blood Mark (his marks heal him when hit), Shadow Bind (Phase 2+, Slowness II + Weakness), or Crimson Strike (Phase 3 only, 10% weight, executes below 30% HP).
Blood Pool Totems
13 blood totem dummies spawn 5-12 blocks around him. Each ticks damage to players who step onto its 1.3-block hitbox and detonates at end. Available Phase 2 and 3.
Bleeding Heart Void
Not a permanent structure. Triggers only after he drops under 50% HP, with a 20% chance on damage. He goes damage-immune while the heart pulls players, damages the inner ring, and spawns Fighter minions. Clear every minion or it explodes at the end of its timer.
Pulse Lock
Phase 3 only. Picks one random player in a 25-block radius, spawns a Blood Source dummy 5-10 blocks away, and locks them with a Pulse Lock aura for 30 seconds. Destroying the source dummy strips the lock early.
Minion max-HP buff
While at least one THE_CRIMSON_MINION is within 50 blocks, the boss gets a stacking max-HP buff. Kill all minions to shave that buff and reduce his HP pool.
Minion consume-heal
When his HP drops under 80% and he has minions nearby, he pulls the closest one in, removes it, and heals himself.
Emergency Protocol
Anti-burst safety net. If a single damage tick exceeds 120 (solo) / 180 (2p) / 250 (3+ players), it fires a mass-heal + short damage immunity + minion flood + arena lockdown. 90-second cooldown.
Arena Auto-Build / Undo
Three schematics live in the pack. The main arena pastes on spawn, and additional layers paste on entering Phase 2 and Phase 3. Everything undoes on death or despawn.
Entities
The Crimson Reaper
Main boss. 10,000 HP husk disguised as the Reaper skin. Three health-based phases, on-hit combo damage, Bleeding Heart Void trigger under 50%, Final Stand cinematic under 5%.
Crimson Minion
THE_CRIMSON_MINION. 12 HP, 2 damage, Slowness X so they barely move. Alive minions grant the boss extra max HP and let him heal by consuming one.
Crimson Fighter
THE_CRIMSON_FIGHTER. 5 HP, 0 base damage. On attack rolls a random effect: basic 2 crit, self-explosion for 3, slow, poison, or throw. Auto-removed if the boss dies.
Crimson Hunter
THE_CRIMSON_HUNTER. Protector faction. Runs to the lowest-HP nearby player and heals them. Deals only 1-2 damage to non-player targets. Not a hostile add.
Blood Source Dummy (Pulse Lock)
Spawned per Pulse Lock, 5-10 blocks from the locked player. Kill it to strip the aura.
Bleeding Heart Dummy
Spawned during the Bleeding Heart Void event. Pulls players, ticks damage in the inner ring, and spawns Fighter minions.
Blood Pool Totem
13 dummy totems spawned in a ring around the boss during Blood Pool Totem. Each ticks damage and detonates at the end.

Requirements
The pack's own file lists these plugin requirements:
- MythicMobs 5.9.0+. Runs the boss, minions and every skill
- FAWE (WorldEdit). Pastes and undoes the three arena schematics
- LibsDisguises 11.0.6+. Applies the Reaper and minion custom skins
- MythicCrucible 2.2.0+. Powers the custom items on his drop table
- PlaceholderAPI 2.11.6+. Used for boss bar and messaging placeholders
Drop the pack folder into MythicMobs and put all three schematics (arena and two paste layers) in your FAWE schematics folder. The arena pastes itself on spawn and undoes on death or despawn.
Give the spawn area a clear footprint before summoning. The pack ships schematics for the main arena plus additional Phase 2 and Phase 3 paste layers.
