# Sleepwalker Attributes

Every Sleepwalker NFT has a specific set of attributes that impact their performance during missions. Players can upgrade their **Sleepwalker's Attributes** using **Attribute points** earned through **leveling up**.

Each Sleepwalker possesses four distinct attributes:

1. **Stability**: This attribute mitigates the loss of Portalite when the portal opens late. Each point decreases the loss by 0.2%, with a maximum reduction of up to 50%.
2. **Capacity**: This enhances the Portalite capacity that the Sleepwalker can transport from their dimension through the portal. Each point augments the capacity by 0.5%, allowing for an increase of up to 100%.
3. **Mentality**: This reduces the decline in Durability. Normally, a Sleepwalker loses 4 Durability points with each play. However, for every 100 points in Mentality, the loss decreases by 1, down to a minimum loss of 1 per play.
4. **Chronoshift**: This attribute decreases the time zones within which the Sleepwalker can intervene to save the world. Initially set to a 24-hour zone, every 25 points in Chronoshift reduce this window by 2 hours, to a minimum of an 8-hour zone.

**Durability** is a critical measure for each Sleepwalker, with a maximum of 100 points. Regular activity reduces Durability by 4 points per session. The reward efficiency of Portalite decreases by 20% for every 20-point reduction in Durability, meaning:

* At 80/100 Durability, Portalite earnings drop to 80%.
* At 60/100 Durability, earnings drop to 60%.
* At 40/100 Durability, earnings drop to 40%.
* At 20/100 Durability, earnings drop to 20%.
* At 0/100 Durability, the player cannot earn rewards.

Players can "Repair" their Sleepwalkers at any time to restore Durability. Additionally, depending on their rarity, Sleepwalkers receive bonus **Attribute Points** with each level up.
