Noble Phantasm

FateGO Cross-Calibur

I have been waiting for this moment. Altereactor, critical limits exceeded. Through my darkness's brilliance, return to elementary particles! Cross-Calibur!

~ MHX Alter using her Noble Phantasm

Cross-Calibur: Twin Black Dragon Sword of Promised Victory: A variation of the original Excalibur. MHX Alter lunges at her opponent and slices them repeatedly, before overloading her Altreactor and creating an X-shaped blast from a surge of mana, reducing the target to elementary particles. Additionally, much like MHX's Secretcalibur, it deals additional damage against swordsmen.

Class Skills

Mad Enhancement: The source of the Berserker class's power, raising their statistics in exchange for a loss of sanity. Despite MHX Alter's C-Rank in this skill, she maintains much of her sanity, with her personality being more bookish, as opposed to robbing her of her sanity and reasoning. As is standard, it also ranks up all of her parameters besides Luck and Mana.

Personal Skills

∞ Black Bean Paste: An item in MHX Alter's possession, made through the six fundamental forces of Desire (Soul), Sugar (Power), Sales Location (Space), Cost Price (Reality), Production (Time), and Demand (Mind). While it is said to grant its wielder infinite power and turn half of the universe into a confectionary factory with a fingertip, MHX Alter does not know how it functions. It is a parody of The Infinity Gauntlet

Altreactor: A mana conversion reactor empowered by Alternium crystals in her body. It converts calories and sugar to magic energy, allowing her to receive a steady supply of mana by consuming food.

Instinct: The power to "feel" the course that leads to the best possible outcome in battle. While MHX Alter's mind is insatiable and lazy, she has both refined her skill with the sword and pushed it to the extreme, granting her a C-Rank in this skill.

Sovereign's Invisible Hand: A skill denoting lessons taught to her by Agravain, instructing her on how to be a dark emperor. Functionally similar to Charisma, it allows her to bring out the capabilities of her equals to their utmost potential while reading the flow of battle of her enemies.
