Vantablaze
Vantablaze was commissioned, or so its current owner insists, from a storm-caller artificer who worked exclusively for performers and champions who understood that winning was only half the job. The blade was folded with captured thunderhead lightning and etched with a proprietary rune sequence that ensures no two discharges look quite the same, though they are always recognizably the same blade. Scholars of magical metallurgy have noted the runeform is unusually legible, as though the maker intended it to be studied and discussed.
Mechanics
A storm-forged greatsword that channels lightning into blinding visual spectacle and battlefield-dominating power, making its wielder the undeniable center of every fight.
Stormcraft Blade
You gain a +3 bonus to attack and damage rolls made with this magic weapon. On a hit, the target takes an extra 2d8 lightning damage as arcs of brilliant white lightning cascade visibly across the blade and leap to the wound. The lightning is silent for a half-second before a sharp crack of thunder follows, a signature effect that experienced observers recognize as distinctly yours.
Brand Presence
While you wield Vantablaze, your appearance is unmistakable. The blade continuously sheds bright light in a 20-foot radius and dim light for an additional 20 feet. You have advantage on all Charisma (Persuasion) checks when the other party has witnessed you land at least one attack with Vantablaze during the current or most recent combat encounter. Additionally, you cannot be mistaken for another creature by mundane means, magical disguises and illusions applied to you still function, but any creature that has seen you fight with this blade in the past month recognizes you instantly on sight, regardless of mundane disguise.
Signature Strike
When you score a critical hit with Vantablaze, instead of rolling the extra damage dice normally, the lightning discharge resolves as a free additional attack embedded within the same action, not costing a bonus action or any other resource. Make one extra attack against the original target or any creature within 10 feet of it. This extra attack is made with Vantablaze and deals its normal damage plus 4d8 lightning damage on a hit, regardless of whether it also scores a critical hit. The lightning discharge is visible to all creatures within 120 feet.
Storm Finale
Once per dawn, as an action, you drive Vantablaze into the ground or raise it skyward and release a full discharge. Each creature of your choice within 30 feet of you must make a DC 19 Dexterity saving throw, taking 10d8 lightning damage on a failed save or half as much on a success. After the discharge, each creature that failed the save is outlined in crackling blue-white lightning until the end of your next turn, they shed dim light in a 5-foot radius, cannot benefit from invisibility, and each attack roll made against them has advantage. The visual spectacle of this ability is visible to all creatures within 500 feet.
Tested Under Fire
You have resistance to lightning damage while attuned to Vantablaze. When you take lightning damage from any source, the absorbed energy causes the blade to visibly brighten for 1 minute, a detail your audience tends to appreciate.
DM Notes
Balance considerations: The +3 bonus combined with 2d8 bonus lightning damage on every hit is strong but appropriate for legendary rarity, the secondary effects reward spectacle rather than stacking raw numbers. Signature Strike's embedded free attack on a critical is the headline Legendary mechanic; it deliberately sidesteps the action economy in a way that rewards aggressive play without requiring resource expenditure, creating exciting moments organically. At 5th-level+ Fighter with Extra Attack and Action Surge, the crit rate is high enough that Signature Strike will fire reasonably often, DMs should expect this player to crit frequently and plan encounters accordingly. Storm Finale (10d8 to all enemies in 30 feet, save DC 19) is a powerful once-per-dawn nova; it is comparable to a Cone of Cold centered on the wielder but with advantage-granting secondary effect, so DMs should treat it as a major turn in combat. Brand Presence's social benefit is deliberately powerful for a character whose identity is built around a personal brand, DMs should lean into NPCs recognizing the wielder, having opinions about their fighting style, and treating them as a celebrity, which creates hooks for both positive and negative narrative consequences. The light emission cannot be suppressed, meaning stealth approaches while wielding Vantablaze are essentially impossible, this is an intentional tradeoff that rewards heroic, visible play over subtlety.
