# Passive Skills

Passive skills provide permanent advantages to the node. 

The skills appear in the node during the building process or upgrading (buying items at the Dealer).

Players cannot choose a skill, it is randomized through onchain mechanics and there is an equal 25% chance for the skills to be one of four types.

* **Hashrate Boost**: Permanently increases the node's base hashrate by a percentage which varies by the node tier.
* **Cooldown Reducer**: After the miner extracts their node rewards, the automatic cooldown is applied and users wait to redeploy the node. This skill shortens the 15–30 minute waiting period required after extracting rewards before a node can be redeployed. Cooldown rate is also randomized through extraction transaction onchain characteristics.&#x20;
* **Deterioration Reducer**: As in real life - nodes lose power naturally over time. This skill lowers the rate at which a node loses power while deployed (base rate is 1% per hour), helping to maintain effective hashrate for longer periods.
* **Event Shield**: Protects against negative datacenter events, allowing for partial payouts during Blackouts and reducing the amount of rewards stolen during Siphons. (we'll cover the events in the datacenters in the next article)

Check out the % effect ranges for every skill, when rolled it is randomized within the range according to the node tier:

### Skill Stacking Rules

Stacking: A single node can have a maximum of two of the same skill type.

Max Slots: The total number of skill slots depends on the tier, ranging from 2 slots for Common/Uncommon nodes to 4 slots for Superior nodes.

Modification Items: There are two items that can help you modify the passive skills on your node:

* Flux Rescript to reroll an existing skill&#x20;
* Flux Expander to attempt to add a new skill slot.

To buy modification items go to `Command` >> `Dealer` and select an item for the node of your tier and good luck rolling!
