+### Additions
+- Rebuilt Pokémon AI to use Minecraft's Brain system, allowing for more complex behaviours and interactions.
+  - As an early pass of this, pastured Pokémon will now sleep when appropriate, and may come up to you when they see you.
+  - Probably also added a whole bunch of bugs.
+- Added a Behaviour Editor to the NPC editing screen.
+- Added /behaviouredit command for opening the Behaviour Editor on Pokémon and NPCs.
+  - Editing variables for Pokémon is not yet supported.
+
+### MoLang & Datapacks
+- Added a `behaviours` datapack folder which motivates the Behaviour Editor screen on NPCs and Pokémon.
+- Added many default behaviours.
+- Removed many NPC presets that now exist as behaviours. This is a breaking change if you are using NPCs with these presets. 
+  - NPCs with these presets should be modified to instead list under `"behaviours"` all the equivalent behaviours.

 - Fixed an issue with newer versions of Fabric API where underground Pokémon were spawning in The End.
 - Fixed spawning not working well when you're at high points surrounded by lower altitude spawning areas, such as flying.
 - Fixed certain Pokémon with forms not having appropriate stock Pokédex entries.
+- Fixed dragon's breath not being usable on the restoration tank when it should be
+- Fixed Moon Stones not interacting properly with dripstone blocks.
 
 ### Developer
 - A finished battle now has winners and losers set inside of `PokemonBattle` instead of them always being empty.

+A "Brain" is a Java Edition AI concept for more modern entities. It has tasks that are listed inside 'activities',
 and in some cases a schedule which determines which activities will occur during different times of the day. There is
 also a set of core activities, and a default activity. In Minecraft, the most complex usage of the Brain AI system 
 is on villagers which have schedules that control their behaviour during the day and night as well as child villager play behaviours.

+Cobblemon's Pokémon and NPCs use the Brain AI system. As part of that, Cobblemon added the concept of a Behaviour Configuration

 By default, without any brain configuration, the default activity will be `minecraft:idle` and the core activities will be `[minecraft:core]`.
 The activities would not have any tasks though.

 ### set_default_activity

-### apply_preset
-The `apply_preset` type applies a preset to the brain. Brain presets are JSON arrays under the `brain_presets` datapack folder. 
-This is a way to apply a set of configurations to the brain.
-- `preset`: The name of the preset to apply. This is the name of the file in the `brain_presets` folder without the `.json` extension.

+- `behaviours`: A list of behaviour resource locations to apply. This is the name of the file in the `behaviours` folder without the `.json` extension.

+- `visible`: Whether the behaviour should be visible in the UI. Defaults to `true`. If it is not visible, name and description can be left out.
+- `name`: The name of the behaviour. This is used in the UI to label the behaviour. This can be a translation key.
+- `description`: A description of the behaviour. This is used in the UI to describe what the behaviour does. This can be a translation key.
+- `entityType`: The entity type that the behaviour applies to. Defaults to null. This is used to determine if the behaviour should be applied to the entity type..

+Example behaviour (`uses_healing_machine.json`):

-[
-  {
-    "type": "add_tasks_to_activity",
-    "activity": "idle",
-    "tasksByPriority": {
-      "1": [
-        "heal_using_healing_machine",
-        "go_to_healing_machine"
-      ]
+{
+  "name": "cobblemon.behaviour.uses_healing_machine.name",
+  "description": "cobblemon.behaviour.uses_healing_machine.desc",
+  "entityType": "cobblemon:npc",
+  "visible": true,
+  "configurations": [
+    {
+      "type": "add_tasks_to_activity",
+      "activity": "idle",
+      "tasksByPriority": {
+        "1": [

+      }
     }
-  }
-]
+  ]

 ```
+
+### add_variables
+The `add_variables` type adds some number of MoLang variables to the entity that can be configured in-game or left with defaults.
+- `variables`: A list of objects, each representing a variable that can be configured.
+
+Each variable has the following properties:
+- `variableName`: The name of the variable. This is the name that will be accessible from MoLang scripts.
+- `defaultValue`: The default value of the variable. This is a MoLang expression that will be used if the variable is not set.
+- `displayName`: The display name of the variable. This is used in the UI to label the variable. This can be a translation key.
+- `description`: A description of the variable. This is used in the UI to describe what the variable does. This can be a translation key.
+- `type`: The type of the variable. This can be `TEXT`, `NUMBER`, or `BOOLEAN`.
+
+Example:
+```json
+{
+  "type": "add_variables",
+  "variables": [
+    {
+      "variableName": "can_heal_using_machine",
+      "defaultValue": "false",
+      "displayName": "Can Use Healing Machine",
+      "description": "Whether or not the entity can use a healing machine.",
+      "type": "BOOLEAN"
+    }
+  ]
+}
+```
+
+### set_variables
+The `set_variables` type sets some values for pre-established variables. This is useful in cases where a preset has defined a variable
+but it's locked in by a specific entity using that preset. This strongly forces the variable to a specific value. In future this
+probably should deregister the variable so that the client cannot edit them once they've been forced, as currently that will
+be possible yet the value will get repeatedly overwritten.
+
+The values inside the variables map can be MoLang expressions (with `q.entity` as the entity) or simple JSON primitives.
+
+Example:
+```json
+{
+  "type": "set_variables",
+  "variables": {
+    "aggressive": true,
+    "attack_range": "10"
+  }
+}
+```
+
+### script
+The `script` type executes a registered MoLang script which will apply some changes to the brain or entity. This can be 
+useful if the goal is to apply some kind of configuration to the entity that would otherwise be performed by an NPC preset
+or NPC class. `q.entity` will refer to the entity. This is powerful when combined with [add_variables](#add_variables)
+configs in the same behaviour preset.
+
+Example:
+```json
+{
+  "type": "script",
+  "script": "cobblemon:configure_npc_party"
+}
+```
+
+### custom_script
+The `custom_script` type executes a custom MoLang script from this config which will apply some changes to the brain or
+entity. This is useful for when you want to apply some kind of configuration to the entity that would otherwise be
+by an NPC preset or NPC class. `q.entity` will refer to the entity.
+
+Example:
+```json
+{
+  "type": "custom_script",
+  "script": "q.entity.set_pathfinding_malus('WATER', -1);"
+}
+```

 ### look_in_direction
 The 'look_in_direction' type creates a task that will make the entity look in a specific direction at all times where they aren't being told to look elsewhere.
 - `yaw`: A MoLang expression that determines the yaw angle (degrees) of the entity. Defaults to `0`.
-- `pitch`: A MoLang expression that determines the pitch angle (degrees) of the entity. Defaults to `0`.
+- `pitch`: A MoLang expression that determines the pitch angle (degrees) of the entity. Defaults to `0`.
+
+### move_to_owner
+The 'move_to_owner' type creates a task that will make the entity move to its owner. This will only work for entities that
+can be owned, like Pokémon.
+- `condition`: A MoLang expression (with `q.entity` as the entity) that determines if this entire task should exist on the entity or not. This runs at the time of entity creation, not on tick.
+- `completionRange`: A MoLang expression that determines the distance from the owner that the entity needs to be for the path to be considered complete. Defaults to 4.
+- `speedMultiplier`: A MoLang expression that determines the speed multiplier for moving to the owner. Defaults to 0.4 which is slightly above the normal walk speed.
+- `teleportDistance`: A MoLang expression that determines the distance from the owner the entity must be before it resorts to teleporting. A value of -1 will cause it to never teleport. Defaults to 24.
+- `maxDistance`: A MoLang expression that determines the maximum distance from the owner that the entity can be to move to them. Defaults to 14.
+
+### point_to_spawn
+The 'point_to_spawn' type creates a task that will make the entity point to the spawn point of the world whenever they
+are not moving and are idling. This is basically only here for Nosepass.
