[Sear Bloodcrow]
As a "forbidden creature" in its parasitic form.
Once released, Sear Bloodcrow would select a "host."
The host could improve the cultivation progress of Sear Bloodcrow through feeding and nurturing.
The higher the cultivation progress, the more powerful "forbidden abilities" the host could gain as a reward from Sear Bloodcrow.
Cultivation progress: 20% [Sear's Word of Truth].
When the Bloodcrow locks onto a target and lands on them,
the targeted unit would be unaware of Sear Bloodcrow's presence.
The Bloodcrow would force the target to speak the truth and the targeted unit would not suspect their own words.
The host could exempt themselves from the influence of True Word witchcraft and magical methods.
