Elite Creatures Reborn

Creatures spawn with mutations — named, visible traits that change how a fight goes. A Mad greydwarf comes at you twice as fast on half the health. A Bloated draugr takes twice the killing and then explodes in your face. A Devouring wolf eats the boars around it and grows on what it eats until it comes looking for you.

Bosses take an aspect instead: one modifier, shown at the altar before you summon, that changes what kind of fight it is. A Twin Bonemass comes as two sharing one health pool; a Reflective Moder hurts you with every hit you land.

The world hardens as bosses fall: every boss's first defeat raises the world tier, and each tier makes stars and mutations more common everywhere. Tamed creatures pass their traits on: a newborn inherits a mutation and stars from its parents.

Rebuilt from scratch. This release covers mutations, stars, world tiers, breeding, loot and boss aspects; the rest returns over the next releases.

Mutations

Ten, one per creature by default, each with its own colour and its own name on the nameplate.

Mutation power fields

mutation power in the rule file sets how strong each mutation is, in named fields rather than positional numbers. A field marked (enhanced) is multiplied by large star power on a large star; a cost field never is. Any mutation can also be switched off entirely with mutations enabled, regardless of its chance curves.

• Mad - move/attack speed multipliers (enhanced); health multiplier, its cost
• Bloated - health multiplier (enhanced); delay seconds from death to the blast, which goes off at the corpse's resting place; damage (enhanced) and radius (enhanced) of the blast; blast effect/warning effect vanilla prefabs for the explosion and the pre-blast warning
• Cloaked - reveal distance metres to become visible (enhanced); fade time seconds to phase, 0 snaps; fade margin extra metres before fading back out, to stop strobing
• Splintering - damage multiplier per split; max generations cascade-depth cap, 0 = unlimited; max descendants live-descendant cap, 0 = unlimited
• Leeching - regen percent max health per second, never enhanced; regen cap hard HP/s ceiling on a single tick, so a huge-health creature cannot out-heal a fight; combat cooldown seconds since its last damage taken before regen resumes; lifesteal percent of damage dealt returned as health (enhanced)
• Warding - reflect percent of incoming damage returned (enhanced); knockback force on a melee attacker (enhanced)
• Plated - armour percent of incoming damage cut at full health, to 0 hurt (enhanced); max reduction hard ceiling on that percent, so enhancement cannot approach invulnerability; damage percent bonus at zero health, to 0 full (enhanced)
• Miasmic - cloud life seconds a dropped cloud lasts; cloud damage strength of the vanilla Poison a cloud or hit applies, not direct damage (enhanced); clouds per second while moving (enhanced); cloud radius metres; cloud effect/body effect vanilla prefabs for the trail cloud and the permanent worn poison look (cosmetic)
• Devouring - absorb health/absorb damage percent kept permanently from a victim (enhanced; an instant kill always lands the killing blow, so the full amount is kept); slow per 100 health, its cost; move base speed multiplier before the slow (0.5 halves it; not enhanced); player threshold fraction of a player's max health a hit must pass before it hunts players for good; devour cooldown seconds after a meal before it can eat again
• Thieving - max items the most it will ever hold (enhanced), hard-capped at 8; never takes equipped gear or more than one item per landed hit, and gives back everything it holds when it is killed

Stars

Beyond vanilla's two, counted in fives on the nameplate: a small star is one, a large star is five. A mutation on a large star is stronger. Star chances and mutation chances are set per biome, so the Meadows stay the Meadows.

Bosses have their own star table, the same for the whole world, and nine in ten stay plain by default. A boss's stars are drawn under its health bar at the top of the screen.

World tiers

The world starts at tier 0 and goes up one tier the first time each boss is defeated - by anyone, in any order - so the seven bosses take it to tier 7. Killing a boss again changes nothing. Every rise is announced to everyone on the server.

Each tier makes stars and mutations more common in every biome while keeping each biome's character. At the default settings, by tier 7 the share of unstarred Meadows creatures falls from 73 in 100 to 44, five-star Plains creatures rise from 5 in 100 to 22, and every mutation chance doubles. Bosses are unaffected, and creatures already alive keep what they rolled - the tier decides what the next one rolls. A world that killed bosses before the mod was installed starts at that tier.

elite tier shows any player the current tier, what it is doing to the rolls, and which bosses count. The world tiers: block in the rule file has the off switch, the list of bosses that count (a modded boss counts once its defeat key is listed; elite tier shows every boss's key), and the star and mutation boost for each tier.

Breeding

Tamed creatures keep their traits and pass them on. A newborn - a pup, a piglet, a calf, or an egg and the chick that hatches from it - takes one of its parents' mutations whenever either has one, and a star count from 0 up to its stronger parent's, every count equally likely. Two plain parents have plain young and nothing new is ever rolled, so a strong line stays strong only if you keep the good ones.

Young creatures keep their traits when they grow up. Eggs keep theirs when carried, and say what they will hatch ("Hatches with 2 stars, Leeching") on their hover text and tooltip; an egg's stars are its quality, so eggs of different stars do not stack. A bred mutation behaves exactly as it does in the wild - a Miasmic pet still trails poison. The breeding: block in the rule file has an off switch and the mutation chance (100 by default).

Boss aspects

A boss never takes a mutation. It takes an aspect, which is in its name - "Enraged Eikthyr" - and on its altar before you commit: hover the offering bowl to see the current aspect, what it does, what it pays, and how long until it shifts. Every altar shifts to a different aspect each in-game hour (75 real seconds), so a group can wait for the fight it wants. The aspect on the bowl when you make the offering is the one you fight. A boss with no altar - the Queen, or a console spawn - rolls its aspect when it first appears.

Everything is in the aspects: block under bosses: in the rule file: the off switch, the shift interval (0 fixes each altar), the chance of each outcome, the loot multiplier, every aspect's numbers, and per boss the creatures Summoner calls and, optionally, which aspects that boss may roll.

Loot

What a kill drops is governed by a loot: block in the rule file. Four modes, chosen for the whole world: Vanilla (drops untouched), Scaled (quantities raised by the per-star drops line), Rolled (the creature's own drop table rolled once more per star, each roll independent — the default, so a hard fight has a real chance at the rare thing), and Curated (per-creature rules decide everything). An extra roll chance line and a max extra rolls cap tune Rolled; a global multiplier and a separate boss multiplier scale everything after the mode, and a boss's aspect multiplies its drops on top - even in Vanilla mode, where it is the only thing that does. Trophies are never multiplied unless you switch that on — one kill, one trophy.

Per-creature rules in the same file, matched by prefab name, override any of it: a creature's own drops line, adjusted or removed rows of its drop table, extra drops with their own chance and amounts. elite reference writes creature_reference.yml with every creature the game knows — modded ones included — under its exact prefab name with its vanilla drop table; paste it and creature_rules.yml at an AI assistant, describe the economy you want, and drop the rules it writes back into the file.

Configuration

Two files, both written and documented on first run, both hot-reloaded while you play:

• BepInEx/config/gglasgow.elitecreaturesreborn.cfg — the settings: star chances, mutation chances and mutation strength per biome, colours, nameplate distance, and an off switch for everything.
• BepInEx/config/creature_rules.yml — the rule file, for anything too structured for a flat settings file, including a mutations enabled switch that turns any mutation off everywhere.

A server binds connected players to its own rules. Display preferences — colours, tint strength, nameplate distance, whether trait names show at all — stay with each player and are never locked.

Console commands

Install

With a mod manager, install it. By hand, drop EliteCreaturesReborn.dll into BepInEx/plugins. Requires BepInEx. On a server, install it on the server and on every client.

Multiplayer

Creature state travels in the world data the game already shares, so every player sees the same creature with the same traits. Install it on the dedicated server as well as the clients.

Files

• plugins/EliteCreaturesReborn.dll — the mod, a single merged assembly
• config/gglasgow.elitecreaturesreborn.cfg — settings
• config/creature_rules.yml — creature rules

Building

.NET SDK 8, with Valheim installed:

dotnet build EliteCreaturesReborn/EliteCreaturesReborn.csproj -c Release

Override -p:GamePath=..., -p:BepInExCore=... or -p:ModLibsPath=... if your layout differs. The build merges the shared libraries into one DLL and writes it to dist/.

Changelog

3.13.4

• A new install's rule file has short comments; the full reference is linked at its top.
• Shorter store page; the reference (mutations, aspects, rule fields, commands) is on GitHub.

3.13.3

• Warding no longer draws particles: a reflect is marked by sound alone, the Staff of Protection's shield at 30% volume.
• The Reflective boss aspect's tell changes the same way.
• Devouring no longer draws a burst when it eats; the sound is unchanged.

3.13.2

• The world tier boxes show only with PackPanel; without it the inventory and HUD stay as the game draws them.

3.13.1

• Fixed: the inventory broke with Jewelcrafting, CurrencyPocket, OttoPay, TrashItems or Quick Stack Store Sort Trash Restock installed.
• Those mods' boxes join the stat column; TrashItems' trash can takes dragged stacks there.
• OpenKeep 1.8.0 to 1.9.0 and PackPanel 0.1.0 to 0.2.0 have the same column: update them too.

3.13.0

• Devouring eats only creatures with at most 125% of its current health (max prey health, 0 lifts the limit).
• Devouring eats one creature per star, at least one (min meals), then is sated and acts like its kind.
• A devourer's nameplate shows what it ate (Show devoured creatures, Devoured creature icon size); so does elite inspect.
• The devour flash is a fifth of its size, and its screen shake is felt only close by.
• Bloated's fuse is 1.7 seconds; an older creature_rules.yml keeps its own delay: 2.0.

3.12.0

• New box with the world tier under the minimap (Show world tier under minimap).
• The tier reads as one number ("3"); hovering it shows the total.
• The inventory's stat plates are square boxes in a column.
• Thieving steals only with melee hits, never on a parry or dodge, and with PackPanel never from its slots.
• On a grid wider than eight, thieves no longer spare the top-row cells right of the hotbar.
• Elite Creatures Pack: a sleeping mimic hides its traits; the kraken never rolls Twin or Phantom.
• Warding's max reflect now caps everything reflected to you per second, not per hit.
• Rule changes reach loaded creatures' mutations at once.

3.11.0

• elite purge 30 removes marked creatures within 30 m only; without a number it still removes every loaded one.

3.10.0

• With GrindstoneSkills 0.7.0 or later, Husbandry's "Better offspring" can give a newborn one more star.

3.9.1

• Starred creatures wear the game's own one-star and two-star looks again (a two-star Neck is purple).

3.9.0

• New mutations: Gilded (rare, flees, pays triple loot), Blinking (reappears behind you), Relentless (follows you to 150 m).
• New boss aspects: Adaptive, Fixated, Stormbound, Gravitic and Colossal; one fight in five stays plain.
• Mutation rules per creature under creatures:; two entries for one creature merge.
• Cloaked shows at 10 m (was 6), at 15 m on trolls and lox, and never on drakes.
• Warding reflects only damage taken, at most max reflect (7.5%) of your health; smaller flashes.
• Bloated: a two-second fuse; the corpse vanishes in a smaller blast and drops its loot there.
• Thieving carries one item per star; max items is the minimum, 8 the most.
• Tamed Splintering creatures split into tamed copies.
• Boss damage board moved left; /damage shows it again; damage to Phantom copies counts.
• Fixed: smoke left after a Bloated blast, effects drawn twice, and stolen goods duplicated at dawn.
• Update the server and every player. An older rule file keeps its old numbers until you delete it.
• Gilded ignores mutation chance: stop it with mutations enabled or mutation chances.

3.8.0

• Phantom splits off one copy per player online at 66% and 33% health (split at, per player, health per tier).
• An older rule file's Phantom copies and health are ignored; replace that line to tune it.
• Fixed: Bloated, Warding, Devouring, Thieving, Summoner and Phantom effects drew nothing; Bloated's blast has a sound (blast sound).
• World tier plate in the inventory under the weight (Show world tier).
• Update the server and every player.

3.7.1

• Fixed: with mods that raise creature health (such as Path of Valheim), creatures spawned with 10-15% health.
