The sound of bones being crushed came from ILB's neck. In that instant, ILB broke his own finger, turning it into a twisted, Scarlet rune mixed with blood.

There were two forms of killing curses. The first was to obtain the target's blood, hair, or even clothes and items, and use them as a medium to launch the Killing Curse.

The other form was to use one's own flesh and blood as the price to curse the target.
The premise of this form was that the enemy had caused damage to you.
