Weapon (longsword), legendary (requires attunement)

The thick, grooved blade of this shining silver longsword is lined with etched runes that sparkle blue in the light. Star Razor — known also as Dwueth’var — was thought to have been destroyed or lost after the Calamity, but new rumors suggest that it might be wielded by a half-orc somewhere in Wildemount.

Dormant. While Star Razor is in a dormant state, you can hold this magic longsword and use a bonus action to speak the command word Galas-var , causing the sword to emit a pale blue glow that sheds bright light in a 20-foot radius and dim light for an additional 20 feet. This glow lasts until you use a bonus action to speak the command word again, or until you drop or sheathe the sword.

• While this longsword is glowing, you gain a +1 bonus to attack and damage rolls made with the weapon, and you have resistance to radiant damage.
• You can cast the Faerie Fire spell from the weapon as an action, requiring no components (save DC 13). Once a spell has been cast using Star Razor , that spell can’t be cast from the sword until the next dawn.

Awakened. When Star Razor reaches an awakened state, you gain the following benefits:

• The weapon’s bonus to attack and damage rolls increases to +2.
• When a creature within 5 feet of you hits you with a melee attack, you can use your reaction to create a burst of radiance from the sword, dealing 1d8 radiant damage to the attacker.
• You can cast the See Invisibility spell from the sword as an action, and the save DC for spells cast using the sword increases to 15.

Exalted. When Star Razor reaches an exalted state, you gain the following benefits:

• The weapon’s bonus to attack and damage rolls increases to +3.
• The burst of radiance you can create as a reaction when hit with a melee attack deals 1d12 radiant damage, and you can immediately teleport to an unoccupied space you can see within 15 feet of you as part of the same reaction.
• You can cast the Fly spell from the sword as an action, and the save DC for spells cast using the sword increases to 17.
