So I saw this creature here, really thought it a cool monster, and decided to take a crack at converting this to the real awesomeness of PF1e.
Let me know what you think, if anything should be added, changed, omitted, etc.
Here's the PF2e version link: RHEVANNA

Detaining Strike (Su) Once per round, a creature struck by a rhevanna's melee attack is affected as if by a dimensional anchor spell if they fail a Will save (DC 35). The saving throw is Charisma-based.
Lifedrinker (Su) If a rhevanna kills a living creature of at least half it's own HD (14 HD for a typical rhevanna), it drinks the life force from the kill and regains 40 hit points. If the creature killed is a celestial, the rhevanna regains 80 hit points.
Plunder Life (Su) Any non-fiend creature within the rhevanna's aura receives only half the hit points from any healing magic or effects. The rhevanna regains half the hit points the effect would heal.
Malefic Binding (Su) If the target of a rhevanna's soul bind spell-like ability is a celestial, the gem the celestial is stored in has Hardness 40 and will kill the celestial if destroyed.
