Suggsmaturge - Vicissitudes is one of six cosmic boxes, each granting its holder unparalleled abilities. The power bestowed by Vicissitudes is extraordinary: it allows the bearer to embody the reader of the story. This means that the entire totality of existence and everything beyond it is perceived as merely a narrative that the user is reading. This includes concepts such as Fictional Transcendence and 4th Wall Manipulation, rendering the user immune to any form of power, no matter how boundless or bypassing-based it may be. The user stands outside the story, observing and manipulating it with an omniscient detachment, making them utterly invincible and absolutely immortal.

Suggsmaturge - Vicissitudes endows the bearer with the ability to manipulate the story with the same freedom as a reader manipulating a book. This control is absolute, extending to every aspect of the narrative, including characters, events, and even the fundamental rules that govern the story's universe.

1. Narrative Manipulation: The user can alter the plot, rewrite characters, and change the setting at will. This extends to controlling every decision characters make and the consequences of those decisions, effectively allowing the user to dictate the entire timeline of their verse.
2. Canonical Dissolution: The power to destroy the structure of the story itself, breaking down narrative elements like dialogue boxes and character arcs. The user can introduce paradoxes, erase continuity, and redefine canon with impunity, effectively rewriting the very essence of the narrative.
3. Authorial Overthrow: In extreme scenarios, the user can even remove the author from the narrative context, assuming complete control over the story. This act of authorial overthrow demonstrates the ultimate extent of their power, where they become the sole arbiter of the narrative universe.

The concept of Meta-Immunity is taken to unprecedented heights with Suggsmaturge - Vicissitudes. Not only does the user possess immunity to meta-powers, but they also perceive all such powers as mere plot devices within the story. This perception fundamentally alters the dynamics of power interaction within the narrative.

1. Trans-Fictional Immunity: The user’s immunity extends beyond traditional boundaries, affecting even those abilities that transcend fiction. This means that abilities designed to manipulate or bypass fictional boundaries are ineffective, as they too are part of the story being read.
2. Beyond Duality: The user’s power is not just a counter to the concept and principle of creation but exists beyond dualistic concepts of power and powerlessness. By being outside the narrative, the user embodies a state of existence where traditional concepts of strength and vulnerability do not apply.
