# Attribute Level Link Definitions

> Attribute Level Link Definitions allow designers to create automatic attribute relationships without writing code.

## **Purpose**

Attribute Level Link Definitions allow designers to create **automatic attribute relationships** without writing code.

Example:

* **1 Strength → +10 MaxHealth**
* **Every Dexterity level increases AttackSpeed**
* **Wisdom increases Mana Regen over time**

This system is the backbone of RPG-style scaling.

***

## **Creating a Link Definition**

1. Right-click → Data Asset → `AttributeLevelLinkDefinition`
2. Add an entry to **Links** array
3. Configure:

* Source Attribute (e.g., Strength)
* Target Attribute (e.g., MaxHealth)
* Operation (Add, Multiply, Override)
* Formula or fixed magnitude
* Triggers

***

## **Supported Operations**

UMAS supports:

* Additive (+X)
* Multiplicative (\*X)
* Override (set to value)
* Curve-driven scaling
* Percentage-of-source
* Level-based rules

Examples:

* Add 10 per every level of Strength
* Add 5% of Endurance to Defense
* Override MaxHealth if “Vitality > 50”

***

## **Supported Triggers**

* On source attribute value change
* On source attribute level change
* On profile load
* On effect modify
* On progression update

***

## **Execution Order**

1. Source attribute updates
2. Link definitions re-evaluated
3. Target attribute recalculates
4. Events fire
5. Replication updates clients

UMAS prevents recursive infinite loops.

***

## **Designer Notes**

* Keep formulas simple when possible
* Group scaling logic by category (Combat, Magic, Survival)
* You can stack multiple link assets on one profile

***

## **Developer Notes**

* Link rules are deterministic
* Calculations run through the main modification engine
* Execution is batched for performance
* Order-of-operations mirrors GAS-style modifiers
