Consecration

Consecration (神聖化,Shinseika; Lit: Sanctification): An ability said to have been used by God and was passed down to their slayers. Using this ability a god or slayer is able to transfer a fragment of their power into that of another living being. Upon doing so, said individual gains a boost in power. More advanced users are able to inscribe one of their abilities onto that individual, thus allowing them to use a given spell the god or slayer wielded. However, Consecration is stated as being a double edged sword. While providing a great boost to others, it weakens said user and preventing them from using the given ability. While the user is able to regain the ability they have given, it often results in the death of the individual.
