Rank	User(s)
A 	Tiamat
A 	Tiamat gains a damage boost against Heroic Spirits, Divine Spirits, and all things born of "the Mother's Womb." All Demonic Beasts she gives birth to inherit this Skill.
A 	Heaven's Hole
A 	Possesses a high understanding of lifeforms who discovered the meaning of reproductive acts, or more broadly speaking, the "continuation of the species".
Enables the understanding of the purpose and the meaning regardless of the difference of the form of knowledge.
...You could call it a special attack against religion and ideology.Fate/Grand Order material V — Profile(s) of Kiara Sessyoin and Heaven's Hole, translated by Konchew at Reddit.
A 	Kama/Mara
A 	Assassin Kama doesn’t possess this skill. …… Or rather, she hides it in her other face as Mara.
She has a strong hold over lifeforms that require the "recognition of the living". Although lifeforms with differing forms of intelligence can not communicate their intentions and their meaning, Beast III's devilish wiles do not require connecting through such intelligence and can corrupt her target through emotions alone. One could even call it a special attack against growth, that makes one renounce hard work and compromise that their current situation is already "good enough".Fate/Grand Order material VIII - Beast III/L Servant Profile translated by Konchew
