Weapon (any sword), legendary (requires attunement)
An odd-looking blade that seems to hum with a power not of this world. You gain a +3 bonus to attack and damage rolls you make with this magic weapon. While attuned to this item magical effects and abilities cannot alter your physical form (ex. Enlarge/Reduce, Polymorph, etc.) or ability scores in any way (ex. Belt of Giant Strength, Feeblemind, etc.) other than the Overwrite property.
Reformat. As a bonus action you can reconfigure the teeth of this weapon to take on the form of any sword.
Overwrite. As an action you can touch another creature with this weapon to increase or decrease an ability score of the creature by your Intelligence modifier for 1 minute or until you are knocked unconscious. An unwilling creature must succeed on a DC (8 + your Intelligence bonus + your proficiency bonus) saving throw of the ability score you are attempting to affect to resist this property. This property cannot reduce a creature's ability score below 1 or increase it beyond 30. If this property increases a creature's ability score above 25, the target gains a point of exhaustion after the effect ends. Once you use this property it can't be used again until you finish a long rest.
Malware. When a creature you can see within 60 feet of you makes an attack roll, ability check, or saving throw you can have the creature roll an additional d20. You can choose to use this property after the die is rolled, but before the outcome is determined. You choose which of the d20 is used for the attack roll, ability check, or saving throw. Once you use this property it can't be used again until you finish a long rest or you score a critical hit with this weapon.
Curse: Firewall. When you have used the Malware property of this weapon, it gains a Firewall charge. When you make an attack roll, an ability check, or a saving throw, the DM can spend a Firewall charge to have you roll an additional d20, and then choose which of the d20 you use for your roll.
"Life is but a game" some say. Oh, if only they knew how right they were. How cruel to be subject to the whims of chance and beings that which we cannot bend or break, unable to escape this existence which we find ourselves in. And yet, a question lingers. What being lies at the end of this sickening entertainment that could bind all of creation to its will, and what may it think when we step beyond our domain into theirs? What can come of challenging one that could easily erase our world just as they can create it? Are we forever to be subject to this miserable existence, bound by rules we did not make?
