Stormglass Verdict
Stormglass Verdict was supposedly forged by a Tortle weaponsmith who believed that combat, done correctly, should be indistinguishable from a performance worth watching twice. The blade is cast from a single continuous lightning strike suspended in alchemical crystal, storm-grey with veins of gold that pulse in rhythm with the wielder's heartbeat. Word is the smith submitted the piece to three separate reviewing panels before selling it, and all three awarded it full marks.
Mechanics
A lightning-forged greatsword that crackles with visible arcs of glory, rewards bold attacks with thunderous spectacle, and lets you strike from two places at once.
Verdict Edge
You have a +3 bonus to attack and damage rolls made with this magic weapon. On a hit, the target takes an additional 2d6 lightning damage as a visible arc of electricity leaps from the blade. The lightning is bright and theatrical, it illuminates a 20-foot radius around you until the start of your next turn.
Resonant Strike
When you roll a natural 20 on an attack roll with this weapon, the strike detonates in a burst of radiant lightning. Every creature within 10 feet of the target other than you must succeed on a DC 18 Dexterity saving throw or take 4d10 lightning damage, or half on a success. This explosion is accompanied by a crack of thunder audible up to 300 feet away and a flash of golden-white light visible for miles, if you had any doubt about who made that hit, you don't now.
Phantom Broadcast
Once per dawn, as a bonus action, you project a perfect luminous duplicate of yourself, same gleaming shell, same heroic pose, at a point you can see within 30 feet. The duplicate lasts for 1 minute or until you dismiss it (no action required). While the duplicate exists, whenever you hit a creature with this weapon, you may choose to have the strike appear to originate from the duplicate's location instead of your own. The lightning arc that accompanies the hit visually travels from the duplicate to the target, regardless of where you actually stand. The duplicate has your exact appearance and mimics your combat stances but has no statistics, cannot act, and vanishes if touched or targeted by any effect.
Reviewed by the Storm
This weapon is perpetually clean, dry, and luminous, no mud, blood, rain, or grime adheres to the blade or your hands while you wield it. At all times, a faint crackling corona of lightning plays across the blade and your forearms, providing the equivalent of a torch's light. Whenever you make an attack roll with this weapon while at least one other creature can see you, your shell and arms gleam with prismatic lightning-light for a moment, imposing disadvantage on the next Perception check made to locate you by sound, but granting advantage on any Charisma (Persuasion) or Charisma (Performance) check you make within the next minute, as witnesses can't stop talking about what they just saw.
Arc of Judgment
Once per dawn, when you take the Attack action, you may call down a concentrated bolt of lightning through the blade as part of one of the attacks in that action. That one attack deals an additional 6d10 lightning damage on a hit. If it misses, the bolt discharges harmlessly into the ground at the target's feet, the flash and crack still happen, everyone still sees it, and you may make a DC 14 Charisma (Performance) check; on a success, onlookers are unsure whether you missed or simply chose not to connect.
DM Notes
Balance considerations: The +3 bonus combined with persistent 2d6 lightning damage and a once-per-dawn 6d10 rider makes this a genuinely top-tier damage weapon, appropriate for Legendary but avoid pairing it with other major damage multipliers simultaneously. The natural-20 burst (Resonant Strike) is intentionally theatrical and high-variance; at DC 18 Dex it will hurt clustered enemies badly but is gated entirely on luck, which keeps it exciting without being reliable. Phantom Broadcast is primarily a positioning and flavour tool, it adds no damage but enables creative tactical deception and is the Echo Knight thematic callback expressed through visuals rather than a subclass mechanic gate. 'Reviewed by the Storm' is intentionally dual-use: the disadvantage-on-sound-Perception creates a fun asymmetry (you're both harder to track AND very visible) and the Charisma bonus rewards roleplay moments in downtime or social encounters. The miss-clause on Arc of Judgment is a pure gift to a character whose brand identity matters, no mechanical benefit, just an opportunity for the player to ham it up. Destruction method: Stormglass Verdict can only be unmade by plunging it into the eye of a hurricane while a creature bearing the original smith's bloodline speaks a formal critique of the weapon, rating it honestly and finding it wanting. If the review is insincere or the bloodline is absent, the storm simply spits the blade back out, intact and annoyed.
