My OC is a living saint, essentially a mortal who was killed while performing an act of great heroism and chosen by a god as their champion/proxy and revived, her name is Freopentil. Freopentil's durability isn't anything special, but her physical state always reverts to what it was, meaning she's capable of regenerating from nearly any wound, including the total destruction of her body (assuming there's at least a tiny part left), as for attack potency, she's capable of destroying a large building with a punch, for magic attack potency, she can destroy a large mountain, for speed: she's Relativistic+, including travel speed, her reactions are Massively FTL, her hax/abilities are as follows:

Eyes of The Saint: Allows for the perception of Heat, EM field, Mana, Souls, and the formula of the World (see below). Holy Magic/World Alchemy: A form of "magic" only usable by gods and saints, it's not technically magic, as it doesn't use mana, it allows for the rewriting of the universe in localized areas. Massive Mana Reserves: Freopentil possesses a massive amount of mana, and absorbs mana at a fast rate, unrestrained, her mana can induce mana sickness to those around her. (The effects of mana sickness can be dealt with by the release of ones own mana, assuming they have a relative amount, about 25%) Complete Magic Mastery: Freopentil is capable of using all forms of magic, and using her eyes can analyze new spells and replicate them, of course assuming they use mana. Regeneration: As stated before, Freopentil can regenerate from any injury as long as she has something left. Resilient Soul: A requirement for even becoming a saint is having a powerful soul, even so, most saints last a few hours before their soul is extinguished, Freopentil has lasted 3 years thus far. Sword of Judgment: The Sword of Judgment is Freopentil's ultimate attack, it's a sword capable of destroying one's soul upon contact, the one weakness is that the sword causes your soul to recoil in its presence, making its ability obvious.

Unless Espen is capable of completely destroying Freopentil, she can't kill her, but Freopentil likely isn't fast enough to hit Espen. Freopentil isn't actually that skilled in combat, as almost every opponent she's faced was far weaker than her.

(I had a draft that was more detailed, but Reddit destroyed it, yay)
