This spell is a part of the Loss of Self spell chain and can be found in the Loss of Self rune stone.
Serenity does not lie. It does not exaggerate or dramatize or make things more than they are. It simply shows what is true, with a clarity and completeness that living things spend their entire lives avoiding. Most never have to face that clarity directly. The necromancer has learned to sit beside it comfortably. The target of this spell is not so fortunate. When the necromancer casts The Certainty of Finality they invite Serenity to show the target exactly three things, in order, without mercy and without pause.
The first is their life. In the opening round Serenity lays it out before them; not selectively, not kindly, but completely. Every choice, every moment, everything done and left undone presented with the quiet impartiality of something that has witnessed every life that ever ended. The target is Confused, their attention torn violently between the battle around them and the totality of what Serenity is showing them, all checks suffering a penalty of difficulty level increased by 1 as the mind struggles to occupy two places at once.
The second is their death. In the second round Serenity shows the target how it ends, with the absolute certainty that only Serenity possesses. Not a possibility. Not a fear. A fact, delivered without softening. The target must make a Hard Mental Balance check each round to take any action at all, the body moving sluggishly through motions the mind is already convinced are pointless.
The third is what comes after. In the third round Serenity opens the door to what no living thing has any framework to comprehend, and shows the target the unknown beyond. This is where the vision becomes truly unbearable. Confusion deepens entirely. The target must make a Hard Mental Balance check each round or be unable to act, and even those who succeed find their perception of friend and foe unreliable, the battlefield barely registering against what their mind is being shown.
When the three rounds conclude Serenity releases the target. But the mind does not simply step back from what it has seen. The fourth round finds the target both Stunned and still Confused. The Confusion is the last echo of the unknown clinging to their thoughts. The Stun the body's response to a consciousness that has just been somewhere it was never designed to go and has snapped back all at once. Only when that fourth round passes does the target fully return to themselves, changed in ways they may not yet understand.
