Day & Night Equipment Presets
How the game itself explains this system.
Some weapons, clothing, and consumables can be great in one form and useless in the other.
You can prepare separate Presets of equipment in the Inventory panel for both Human and Vampire forms. The presets change automatically at the beginning of each Day and Night.
Quickslots are a part of Presets.
Press Switch Preset to toggle the preview of Presets.
