From Efyeed, Tiana acquired an innate body physique called Hortar Blood Amber physique.
Once activated, her body can transform into an amber structure, and she gets overall strengthening in her body. All of her body order techniques also become power.
However, that's not all. This physique creates something called Hortar amber blood crystals from her heart blood all the time. Only a tiny amount of her heart blood is consumed every second, every minute to match her natural heart blood recovery process. The limit is 100 Hortar amber blood crystals for now, and she can have 100 Hortar amber blood crystals every two days without feeling a lack of her heart blood.
She can consume these Hortar amber blood crystals to empower her body order techniques, heal severe wounds, enhance her physical body's strength, and such things.
