Chapter 427 Hunting Trophy
As Cain learns more about life force Manipulation in his attempts to perfect Mythic buffs, more things about the vortex become clear to him. In specific, one of the sections of broken runes has become very familiar from his Spell Crafting lessons. It is a much more complex version of the portion of a spell that bonds it to a target.
That gives Cain a great idea. The next section he will be learning after what the book calls an introduction to enhancements is an introduction to curses. They are fundamentally the opposite, in terms of structure, so Cain is hoping that he will learn a structure that will cause the target to reject buffs.
If he applies something like that in the missing section he might be able to force the vortex to eject its occupants.
