Blood Drinking
How the game itself explains this system.
The only way to restore Health in the Vrakhir form is to Drink Blood.
• In combat, use Voracious Bite for a quick sip of the enemy.
• Outside of combat, use Voracious Bite to feed on unaware enemies or neutral creatures.
• You can also feed from Consumable blood vials in your inventory. To access a blood vial in combat, assign it to a Quickslot beforehand.
Exception: on the Story Difficulty, you can drink directly from the inventory anytime.
