Ibaiya Wenet Nebet Gerekh

is the first Noble Phantasm of Tutankhamun.
The lost heart of Tutankhamun. Because its status is thoroughly concealed, this is not information the Master cannot simply uncover on their own. Consuming this Noble Phantasm allows the acquisition of an Arcana of rank B. However, if the Arcana possesses the concept of “a monster or god who accepts the heart as a sacrifice,” the rank will be substantially higher. To activate the Noble Phantasm, Tutankhamun must separate his Spiritual Core from his body and store it in a heart-shaped scarab. 
Employing this Noble Phantom results in inevitable destruction, and surviving the process is nearly impossible. As such, Tutankhamun is exceptionally careful in its use. The status will be hidden from any Master whose intentions are tainted by malice, and the Noble Phantasm would instinctively prevent being used in a manner that betrays Tutankhamun's will. It holds untapped potential as a magical amplifier, but Tutankhamun's youthful and fragile constitution prevents its full utilization.
