Magic Items

This wand has 7 Charges. While holding it, you can use an action to expend 1 of its Charges and choose a target within 120 feet of you. The target can be a creature, an object, or a point in space. Roll d100 and consult the following table to discover what happens.
If the effect causes you to Cast a Spell from the wand, the spell's save DC is 15. If the spell normally has a range expressed in feet, its range becomes 120 feet if it isn't already.
If an effect covers an area, you must center the spell on and include the target. If an effect has multiple possible subjects, the DM randomly determines which ones are affected.
The wand regains 1d6 + 1 expended Charges daily at dawn. If you expend the wand's last charge, roll a d20. On a 1, the wand crumbles into dust and is destroyed.

Nature of the Weave
You have uncovered a series of tomes written by the archmage, Manshoon. By spending 50 downtime days, you gain proficiency in the Arcana skill. If you are already proficient in Arcana, you double your proficiency when making checks with the skill.

Wondrous item, major tier, legendary (requires attunement by a wizard)
5 lb.

This thick leather-bound volume has a desiccated tongue pinned to the front cover. Five of these tomes exist, and it's unknown which one is the original. The grisly cover decoration on the first tome of the stilled tongue once belonged to a treacherous former servant of the lich-god Vecna, keeper of secrets. The tongues pinned to the covers of the four copies came from other spellcasters who crossed Vecna. The first few pages of each tome are filled with indecipherable scrawls. The remaining pages are blank and pristine.

If you can attune to this item, you can use it as a spellbook and an arcane focus. In addition, while holding the tome, you can use a bonus action to cast a spell you have written in this tome, without expending a spell slot or using any verbal or somatic component. Once used, this property of the tome can't be used again until the next dawn.

While attuned to the book, you can remove the tongue from the book's cover. If you do so, all spells written in the book are permanently erased.

Vecna watches anyone using this tome. He can also write cryptic messages in the book. These messages appear at midnight and fade away after they are read.

Weapon (scimitar), legendary (requires attunement)
You gain a +3 bonus to attack and damage rolls made with this magic weapon. In addition, the weapon ignores resistance to slashing damage.

When you attack a creature that has at least one head with this weapon and roll a 20 on the attack roll, you cut off one of the creature's heads. The creature dies if it can't survive without the lost head. A creature is immune to this effect if it is immune to slashing damage, doesn't have or need a head, has legendary actions, or the GM decides that the creature is too big for its head to be cut off with this weapon. Such a creature instead takes an extra 6d8 slashing damage from the hit.

Proficiency with a scimitar allows you to add your proficiency bonus to the attack roll for any attack you make with it.

Martial weapon (trident), melee weapon, legendary (requires attunement by a creature that worships a god of the sea)
4 lb. 1d6 piercing - thrown (20/60 ft.), versatile (1d8)

Held in the dungeon of White Plume Mountain, this trident is an exquisite weapon engraved with images of waves, shells, and sea creatures. Although you must worship a god of the sea to attune to this weapon, Wave happily accepts new converts.

You gain a +3 bonus to attack and damage rolls made with this magic weapon. If you score a critical hit with it, the target takes extra necrotic damage equal to half its hit point maximum.

The weapon also functions as a trident of fish command and a weapon of warning. It can confer the benefit of a cap of water breathing while you hold it, and you can use it as a cube of force by choosing the effect, instead of pressing cube sides to select it.
Sentience.

Wave is a sentient weapon of neutral alignment, with an Intelligence of 14, a Wisdom of 10, and a Charisma of 18. It has hearing and darkvision out to a range of 120 feet.

The weapon communicates telepathically with its wielder and can speak, read, and understand Aquan. It can also speak with aquatic animals as if using a speak with animals spell, using telepathy to involve its wielder in the conversation.
Personality.

When it grows restless, Wave has a habit of humming tunes that vary from sea chanteys to sacred hymns of the sea gods.

Wave zealously desires to convert mortals to the worship of one or more sea gods, or else to consign the faithless to death. Conflict arises if the wielder fails to further the weapon's objectives in the world. The trident has a nostalgic attachment to the place where it was forged, a desolate island called Thunderforge. A sea god imprisoned a family of storm giants there, and the giants forged Wave in an act of devotion to—or rebellion against—that god.

Wave harbors a secret doubt about its own nature and purpose. For all its devotion to the sea gods, Wave fears that it was intended to bring about a particular sea god's demise. This destiny is something Wave might not be able to avert.
Thrown.

If a weapon has the thrown property, you can throw the weapon to make a ranged attack. If the weapon is a melee weapon, you use the same ability modifier for that attack roll and damage roll that you would use for a melee attack with the weapon. For example, if you throw a handaxe, you use your Strength, but if you throw a dagger, you can use either your Strength or your Dexterity, since the dagger has the finesse property.
Versatile.

This weapon can be used with one or two hands. A damage value in parentheses appears with the property—the damage when the weapon is used with two hands to make a melee attack.

Armor (Chain Mail), Legendary (requires Attunement)
