Scaling Mobs
Scale hostile mob attributes over time, configure to your liking
Quick answer
Which Scaling Mobs release should I use?
Scaling Mobs 2.1.0 targets 1.21.10 with Fabric. Do not install it on the client. It must be installed on the dedicated server. All 1 required mods have matching files.
Where it goes
Is Scaling Mobs required on the client, server, or both?
Do not install it on the client. It must be installed on the dedicated server.
This file is marked server-only.
What else does Scaling Mobs 2.1.0 need?
2.1.0. Change the file and its required mods may change too.
Install Fabric API first. We found matching files for this game-version and loader setup.
We only count dependency files that match this setup. A file for another loader does not fill the gap.
Before you install it

About this project
What does Scaling Mobs add?
Scaling Mobs
This is a server side mod that allows for scaling of the attributes health, damage and speed. You can configure it through a file and choose on what days the attributes should be applied/active.
Features include, filtering by mobs and dimensions, scaling by days passed, moon cycle, distance from spawn, distance under sea level. You can scale linearly, exponentially or just apply a constant. You also configure when it is active, for example only at nights or every 7 days.
Here's a list of the configuration options that can be found in the scalingmobs.toml file within the configuration directory.
| Name | Value | Description |
|---|---|---|
| start | Float (default 0) | The start value of scaling |
| max | Float (default MAX_FLOAT) | The maximum value it can scale to |
| min | Float (default 0) | The minimum value it can scale to |
| scalingFactor | "DAYS","DISTANCE_FROM_SPAWN","LUNAR_PHASE","DEPTH","HEIGHT" (default "DAYS") | If scaling by "DAYS" it will increase the scaling factor/variable once per day. "DISTANCE_FROM_SPAWN" will scale by blocks from (0, 0) of where the mob spawned. (Useful to pull out a graphing calculator since it's hard to get right) |
| scalingType | "LINEAR","EXPONENTIAL","CONSTANT" (default "LINEAR") | Should it scale linearly or exponentially |
| increaseFactor | Float (default 1.1) | If scalingType is linear you can calculate final value approcimately by (start + scalingFactor * increaseFactor). If exponential then (start * increaseFactor ^ scalingFactor). If constant (increaseFactor) |
| startingFrom | Integer (default 0) | Determines when the scaling modifier start and is applied depending on the scalingFactor |
| activeNth | Integer (default 1) | A number of 3 means that the attributes will be applied every 3rd value of the scalingFactor. For scaling to be applied this number should be 1. (Do not put it to 0, that will crash the game.) |
| timeWhenActive | "DAY","NIGHT","BOTH" (default "NIGHT") | Determines when the modifier should be active, If "DAY" then it will only be applied at day time. |
| mobFilterType/dimensionFilterType | "INCLUDE","EXCLUDE" (default "EXCLUDE") | Determines if the filters should include or exlude for their respective category. |
| mobFilter/dimensionFilter | String List (default empty) | What shoud the filter contain e.g ["minecraft:wither", "minecraft:zombie"] |
# This is a example config. Each comment describes what the
# setting/modifier under it does
# All health modifiers get applied on top of vanilla/default
# attributes if this variable is set to true
healthAddOnTopOfDefault = true
# All damage and speed modifiers will be applied from 0, without the
# vanilla attributes

# Modifiers where "timeWhenActive" isn't set are only
# active at night because that variables default value is "NIGHT"
# and is set implicitly.
# For every block below Y=63 mobs gain hearts exponentially
# This health modifier follows the formula:
# health = start * (increaseFactor ^ blocksBelowSeaLevel)
# health = 1 * (1.04 ^ blocksBelowSeaLevel)
# Don't forget that this health is added to the mobs default
# damage attribute because we set the "healthAddOnTopOfDefault" variable to true

# Everyday mobs do +0.5 more damage starting from 3 damage.
# This scaling will at most only make mobs do 10 extra damage.
# The scaling is only active every other day i.e day 1,3,5...
