Events Module¶

Last updated: 2026-03-22

The Events module adds world-scale dynamic events that affect all players simultaneously — starting with the Blood Moon, which transforms nights into increasingly dangerous survival challenges tied to a per-player streak and a Sacrifice Arc.

Blood Moon¶

The Blood Moon automatically activates each night when world time crosses tick 13000 and deactivates at dawn (tick 23000). Server operators can also control it manually.

Effects While Active¶

Effect	Detail
Mob level bonus	All Leveled Mob rolls receive +2
Hunter job pay	Multiplied by the configured `kill-pay-multiplier` (default ×1.5)
Particle rain	Red DUST particles spawn around every online player every 3 seconds
Horde waves	A mob horde spawns every `horde-interval-ticks` (default 5 min)

At dawn (deactivation), every online player who survived earns +1 to their survival streak.

Horde Waves¶

Each horde interval, a random online player is chosen as the target. 30 mobs spawn in a ring 18 blocks around them from this pool: Zombie, Skeleton, Creeper, Spider, Witch, Husk, Drowned. All horde mobs are named [Blood Moon] in dark red.

Commands¶

Command	Description	Permission
`/bloodmoon`	Show current Blood Moon status	`nexusprism.events.bloodmoon.admin`
`/bloodmoon start`	Force-activate the Blood Moon	`nexusprism.events.bloodmoon.admin`
`/bloodmoon stop`	Force-deactivate the Blood Moon	`nexusprism.events.bloodmoon.admin`
`/bloodmoon status`	Detailed status output	`nexusprism.events.bloodmoon.admin`

Configuration (`events/config.yml`)¶

blood-moon:
  enabled: true
  world: world                     # The world to watch for time changes
  schedule: RANDOM                 # RANDOM (chance per night) or ALWAYS
  random-chance-per-night: 15      # Chance (%) a Blood Moon occurs each night (RANDOM only)
  kill-pay-multiplier: 1.5         # Hunter job pay multiplier during Blood Moon
  particle-interval-ticks: 60     # How often (ticks) to spawn particles per player
  horde-interval-ticks: 6000      # How often (ticks) to fire a horde wave (6000 = 5 min)
  horde-size: 30                   # Number of mobs per horde wave

Survival Streak¶

Every player has a personal Blood Moon survival streak stored persistently in SQLite (events/events.db).

Event	Streak Change
Survive a full Blood Moon night	+1 (awarded at dawn)
Die during a Blood Moon	Reset to 0

When the streak reaches a multiple of 7 (7, 14, 21, 28...), the player receives a Sacrifice Invitation the next time they sleep.

Streak Difficulty Scaling¶

Higher streaks make every Blood Moon harder — more mob levels, more spawns, and additional mini-boss events.

Streak Range	Level Bonus	Spawn Rate Bonus	Elite Multiplier	Extra Events
1–6	Base	Base	Base	—
7–13	+4	+500%	×3	—
14–20	+7	+700%	×5	Mid-event boss spawn
21+	+10	+900%	Unlimited	Mini-bosses every 5 min

Sacrifice Arc¶

The Sacrifice Arc is a high-stakes optional challenge triggered by the survival streak. It hooks into the Dreams module: when the streak qualifies, sleeping opens a choice GUI instead of a dream cutscene.

Choice GUI¶

A 3-row GUI with two options:

Slot	Item	Action
11	Green Wool — Accept	Teleport to arena, 90-second survival trial
15	Red Wool — Decline	Reset streak, no other penalty

Closing the GUI without clicking counts as Decline.

Arena Trial¶

The player is teleported to the configured arena (or stays in their current location if unconfigured)
A random Anime Boss is summoned — selected from the pool eligible for the player's streak
A 180-second countdown begins with warnings at 60s, 30s, 10s, and 5s

Outcomes¶

Outcome	Result
Survive	Reward granted (default: 3 Diamond Blocks), server-wide broadcast, streak reset
Die	Streak reset to 0
Quit/disconnect	Session cleaned up, treated as failure

Sacrifice Reward Tiers¶

Rewards scale with how many Sacrifices you have completed (every 7 streak milestones).

Streak Milestone	Rewards
7	Tier 1 MMO item + permanent +5 Max HP
14	Tier 2 MMO item + permanent +10 Max HP + 1 stat point
21	Tier 3 MMO item + permanent +2 stat points + cosmetic effect
28	Tier 4 MMO item + permanent +3 stat points + title + boss egg
35+	Multiplying stat points + exclusive anime cosmetic per milestone

Streak Reset After Sacrifice

Completing a Sacrifice — win or lose — resets your streak to 0. Your best streak is recorded separately and never resets.

Configuration (`events/config.yml`)¶

sacrifice:
  arena:
    world: ""    # Leave blank to use the player's current world
    x: 0.0
    y: 64.0
    z: 0.0

Setting Up the Arena

Build a dedicated PvE arena and set its coordinates under sacrifice.arena. Leave world blank to fight in place — useful for testing.

Anime Boss Codex¶

When a Sacrifice is accepted, a random Anime Boss is summoned in the arena. The boss pool available depends on the player's current streak. Each boss has multiple phases, unique mechanics, and a unique drop.

Boss definitions live in events/anime_bosses/*.yml. Health and damage scale with streak:

finalStat = baseStat × (1 + (streak - 7) × 0.2)
