Additional Attributes
Additional Attributes (AA) is the tool designed to simplify introducing of new attributes for characters. Made with performance in mind.
It is for modders, not for regular players. But it is possible that some players will found usefull attached sample
AA consist of 3 parts:
1) esm file - contains service data required for scripts working
2) F4SE plugin with Papyrus scripts for accessing plugin's functionality
3) API Papyrus scripts
AA provides API for managing character's attributes and attributes changes notifications. It can be used for introducing new game mechanics to the game.
Features
1) Actor initialization with registered attributes. In more flexible way than in Creation Kit. Initial value, initial base-value and minimum value can be defined independently. Initialization with randomized values supported out of box. Built-in (hardcoded) ActorValues are not supported. ActorValues with Damage Is Positive flag intentionally not supported. Value of attribute can vary in range only. Exceeding these limits will be reflected in notifications. Initialization is applied at first access to attribute when access performed via API provided.

2) Ability to receive attribute (ActorValue) changes notifications. When attribute is changed via provided API then subscribers will recieve notification about change. Increasing/Decreasing based on RestoreValue & DamageValue. Base value is considered as maximum value for attribute and not changed by API. Can be used on any ActorValue, including hardcoded - notifications will be sent for them too. However, ActorValues with DamageIsPositive flag are not supported.
