Valyn Diving

Dive beneath the surface with a visible breath supply and swim controls. I wanted underwater travel to have clear feedback and a meaningful stamina cost without making shallow water a place where diving stamina resets.

What it does

• Hold Left Control to descend and Space to ascend while diving.
• Watch a blue breath bar next to stamina; breath refills at the surface and Swim skill extends the time underwater.
• Hold Left Shift to swim faster at a higher stamina cost.
• Stamina recovery stays blocked while swimming or submerged, including on the seabed, but works while wading in shallow water.
• Adjust breath time, drowning damage, movement speeds and stamina behavior in the config file.

Settings

Default breath is 30 seconds; Swim skill can double it at skill 100. Shift speed is 1.25×, and ordinary swim stamina drain is 0.85×. Edit BepInEx/config/valyn.mods.diving.cfg after first launch.

Requirements

• BepInExPack_Valheim
• Valheim

The other Valyn mods are optional.
