# Cyberware
## New Cyberware
### Syn-Lungs (Circulatory System)
Syn-Lungs make their return from previous versions of the game! They now reduce the amount of Stamina necessary to Dodge and Dash while on the ground, and reduce the duration of negative status effects from smoking. Syn-Lungs begin at Tier 3 rarity and can be purchased starting at Level 17, as well as upgraded up to Tier 5++.
{% hint style="info" %}
***Developer's Note:*** Syn-Lungs help complement the benefit of the Tailwind perk, which now makes [Air Dashing cost -40% less Stamina](https://wiki.darkfuture2077.com/perks-and-skills#tailwind). Syn-Lungs provide up to the same benefit at Tier 5++, just while on the ground.
{% endhint %}
### Endorphin Regulator (Frontal Cortex)
Endorphin Regulator allows you to consume less alcohol to gain the **Numbed** status, and increases the duration of the effects of Narcotics.
Like Syn-Lungs, Endorphin Regulator begins at Tier 3 rarity and can be purchased beginning at Level 17, as well as upgraded up to Tier 5++.

## Changes to Existing Cyberware
### Second Heart
Second Heart now restores Health *or* Nerve when they deplete, depending on which runs out first. Both effects share the same cooldown. (Example: If you run out of Health and Second Heart triggers, and you then run out of Nerve during the cooldown, Second Heart won't save you.)
