Armory of Selune

The Armory of Selune is a set of five individual magic weapons (Severum, Calibrum, Infernum, Gravitum, and Crescendum) forged by an ancient tribe of moon elves from the Forest of Nep.

The Cult of the Moon crafted these weapons long ago to be used by a moon elf warrior in times of great peril. The cult-chosen warrior discards their old name and dons the title Aphelios, meaning "Against The Sun" in elven. An Aphelios has been a significant force in every large-scale crisis on Mortium, including the unification of the United Dominion and the Great War. In times of peace, the Cult of the Moon separates the five weapons of the Armory and scatters them across Mortium in order to prevent the entire collection from falling into the wrong hands.

After the Great War, the moon elves have since been assimilated into the United Dominion of Ell and Neria. However, many still fervently worship the moon goddess Selune. The few remaining members of the Cult of the Moon have recently received messages from Selune that a new crisis has begun after the assassination of the Lax'Letha family. Though their numbers are few, the cult has chosen a new Aphelios to collect the Armory in the defense of Mortium once again.

The Armory is innately tied with the moon goddess Selune. Only a wielder with moon elf ancestry can use these weapons' abilities. When not wielded by a wielder with moon elf ancestry, the weapons of the Armory will behave as masterwork-quality weapons of the same type.

In addition, a wielder can attune to multiple weapons in the Armory of Selune as if it were one magic item. A wielder attuned to one or more weapons in the Armory can instantly attune to another weapon of the Armory without the prerequisite short rest. The Armory is also treated as one magic item in regards to the maximum amount of magic items attuned by any given person.

Severum, the Waning Moon
Weapon (scimitar), legendary (requires attunement)

Severum is a unique reverse-bladed scimitar shaped like a thin crescent moon. The blackened edge of this scimitar is on its concave side, as opposed to the convex side like that of a normal scimitar. Severum functions like a silvered weapon, making it more effective against monsters with immunity or resistance to nonmagical weapons. Like all weapons in the Armory of Selune, Severum's ability can only be activated by a wielder of moon elf ancestry.

'''Onslaught. '''Once per short rest, the wielder can use a bonus action to activate this ability. The wielder can move an extra 30 feet this turn. The wielder also gains an additional +2 AC against opportunity attacks made against them during this turn. During this turn, the space of another creature does not count as difficult terrain for the wielder, but other types of difficult terrain still apply. Severum deals 1d6 radiant damage to all objects or creatures in the same 5-foot square of space as the wielder. This ability's damage increases by 1d6 when the wielder reaches 5th level (2d6), 11th level (3d6), and 17th level (4d6).

Calibrum, the New Moon
Weapon (longbow), legendary (requires attunement)

Calibrum is an ebony recurve longbow strengthened by a strip of thin silver metal on the front of each arm. The arms of Calibrum are tipped with blackened owl feathers which help conceal the sound of Calibrum loosing arrows. If the wielder has advantage on an attack roll using Calibrum, the wielder can add +2 to one or both attack rolls. Like all weapons in the Armory of Selune, Calibrum's ability can only be activated by a wielder of moon elf ancestry.

Moonshot. Once per short rest, the wielder can use a bonus action to activate this ability. The wielder gains advantage on their next ranged attack using Calibrum. In addition, the projectile launched by Calibrum deals an extra 2d4 radiant damage to its target. This ability's damage increases by 2d4 when the wielder reaches 5th level (4d4), 11th level (6d4), and 17th level (8d4).

Infernum, the Waxing Moon
Weapon (whip), legendary (requires attunement)

Infernum is a silver whip ending in a blackened hard tip. The tip of Infernum is magically enchanted to cause a spark of flame upon each successful strike. Infernum deals an extra 1d6 fire damage to any target it hits. Like all weapons in the Armory of Selune, Infernum's ability can only be activated by a wielder of moon elf ancestry.

Duskwave. Once per short rest, the wielder can use a standard action to activate this ability. The wielder strikes Infernum downward in front of them, releasing a 15-foot cone of silver fire outwards from the whip. Each creature in this 15-foot cone must make a Dexterity saving throw. A creature takes 3d6 fire damage on a failed save, or half as much damage on a successful one. The fire ignites any flammable objects in the area that aren't being worn or carried. This ability's damage increases by 3d6 when the wielder reaches 5th level (6d6), 11th level (9d6), and 17th level (12d6).

Gravitum, the Full Moon
Weapon (net), legendary (requires attunement)

Gravitum is a silver shimmering circular net made of glowing thread and silvered metal weights. It radiates moonlight, illumating a 40-foot radius around its wielder with bright light and dim light for an additional 40 feet. The wielder can use a bonus action to deactivate or reactivate Gravitum's illumination. The net is immune to damage and cannot be destroyed. Like all weapons in the Armory of Selune, Gravitum's ability can only be activated by a wielder of moon elf ancestry.

Binding. Once per short rest, the wielder can use a bonus action or reaction to activate this ability. Gravitum's metal weights momentarily increase in density by a massive amount. This causes Gravitum to shove the creature it is restraining to the ground, dealing 2d6 force damage and knocking the creature prone. Additionally, if this ability was activated as a reaction to an attempt to free the creature restrained by Gravitum, it temporarily raises the Strength check to free the creature to DC 25 for this turn. This ability's damage increases by 2d6 when the wielder reaches 5th level (4d6), 11th level (6d6), and 17th level (8d6).

Crescendum, the Eclipse
Weapon (greatsword), legendary (requires attunement)

Crescendum is a silver-bladed greatsword with a single curved and blackened edge. Elaborate golden patterns are embossed along both sides of its blade. Its circular guard is a thick disc of blacked metal with gold-enameled edges, its likeness representing a lunar eclipse of the sun. Crescendum is Selune's most favored weapon in her Armory, and is especially powerful under moonlight.

During the day or indoors, Crescendum gains no special bonuses. However, in the presence of moonlight (even if artificial), Crescendum gains an additional +4 to both its attack rolls and damage rolls.

Like all weapons in the Armory of Selune, Crescendum's ability can only be activated by a wielder of moon elf ancestry.

Sentry. Once per long rest, the wielder can use a standard action to activate this ability. An avatar of Selune called the Sentry comes into existence for up to 1 hour, taking possession of Crescendum from its current wielder and occupying a 5-foot square adjacent to Crescendum's owner. The Sentry appears to be an elven humanoid made entirely of moonlight.

The Sentry is friendly to Crescendum's owner and their companions. The owner rolls initiative for the Sentry, who has her own turns. She obeys any verbal commands the owner issues to her. If the owner doesn't issue any commands to the Sentry, she defends herself from hostile creatures but otherwise takes no actions. The Sentry disappears when she drops to 0 hit points or when this ability ends. When the Sentry disappears, Crescendum drops from the Sentry's former location to the ground. The Sentry grows in power when the wielder reaches 5th level, 11th level, and 17th level.
