Human Form
From V Rising Wiki
Description
Turn into a human allowing you to sneak around unnoticed in human settlements. Be carefull though, the strong-willed can see through your disguise. While in human form you can interact with traders. Human form greatly increases blood consumption rate.
Unlocking
Human Form is unlocked via Beatrice the Tailor.
Usage
While Human Form would seem to be a good option for sneaking around human settlements such as Brighthaven, that would be handled better via Rat Form. Human Form is exclusively used for purchasing goods from traders with silver.
Grandma Form
The Founder's Pack: Eldest Bloodline comes with a special cosmetic variant of Human Form, Grandma Form. This form is mechanically identical to Human Form, and is merely a cosmetic difference.
