Magic Items

Weapon (spear or javelin), very rare (requires attunement)
You gain a +2 bonus to attack and damage rolls made with this magic weapon. When you throw it, its normal and long ranges both increase by 30 feet, and it deals one extra die of damage on a hit. After you throw it and it hits or misses, it flies back to your hand immediately.

Curse. This weapon is cursed, and becoming attuned to it extends the curse to you. Until the curse is broken with remove curse or similar magic, you are unwilling to part with the weapon, keeping it within reach at all times. In addition, you have disadvantage on attack rolls made with weapons other than this one.

Whenever you roll a 1 on an attack roll using this weapon, the weapon bends or flies to hit you in the back. Make a new attack roll with advantage against your own AC. If the result is a hit, you take damage as if you had attacked yourself with the spear.

Wondrous Item, Very Rare

This bag resembles a Bag of Holding but is a feeding orifice for a gigantic extradimensional creature. Turning the bag inside out closes the orifice.

The extradimensional creature attached to the bag can sense whatever is placed inside the bag. Animal or vegetable matter placed wholly in the bag is devoured and lost forever. When part of a living creature is placed in the bag, as happens when someone reaches inside it, there is a 50 percent chance that the creature is pulled inside the bag. A creature inside the bag can take an action to try to escape, doing so with a successful DC 15 Strength (Athletics) check. Another creature can take an action to reach into the bag to pull a creature out, doing so with a successful DC 20 Strength (Athletics) check, provided the puller isn’t pulled inside the bag first. Any creature that starts its turn inside the bag is devoured, its body destroyed.

Inanimate objects can be stored in the bag, which can hold a cubic foot of such material. However, once each day, the bag swallows any objects inside it and spits them out into another plane of existence. The GM determines the time and plane.

If the bag is pierced or torn, it is destroyed, and anything contained within it is transported to a random location on the Astral Plane.

Wondrous Item, Very Rare

This fine wooden box contains 1d4 pots of pigment and a brush (weighing 1 pound in total).

Using the brush and expending 1 pot of pigment, you can paint any number of three-dimensional objects and terrain features (such as walls, doors, trees, flowers, weapons, webs, and pits), provided these elements are all confined to a 20-foot Cube. The effort takes 10 minutes (regardless of the number of elements you create), during which time you must remain in the Cube, and requires Concentration. If your Concentration is broken or you leave the Cube before the work is done, all the painted elements vanish, and the pot of pigment is wasted.

When the work is done, all the painted objects and terrain features become real. Thus, painting a door on a wall creates an actual door, which can be opened to whatever is beyond. Painting a pit creates a real pit, the entire depth of which must lie within the 20-foot Cube.

No object created by a pot of pigment can have a value greater than 25 GP, and the total value of all objects created by a pot of pigment can’t exceed 500 GP. If you paint objects of greater value (such as a large pile of gold), they look authentic, but close inspection reveals they’re made from paste, cookies, or some other worthless material.

If you paint a form of energy such as fire or lightning, the energy dissipates as soon as you complete the painting, doing no harm.

Staff, Very Rare (Requires Attunement by a Sorcerer, Warlock, or Wizard)

This staff has 20 charges and can be wielded as a magic Quarterstaff that grants a +2 bonus to attack rolls and damage rolls made with it. While holding it, you gain a +2 bonus to Armor Class, saving throws, and spell attack rolls.

Spells. While holding the staff, you can cast one of the spells on the following table from it, using your spell save DC. The table indicates how many charges you must expend to cast the spell.

Regaining Charges. The staff regains 2d8 + 4 expended charges daily at dawn. If you expend the last charge, roll 1d20. On a 1, the staff retains its +2 bonus to attack rolls and damage rolls but loses all other properties. On a 20, the staff regains 1d8 + 2 charges.

Retributive Strike. You can take a Magic action to break the staff over your knee or against a solid surface. The staff is destroyed and releases its magic in an explosion that fills a 30-foot Emanation originating from itself. You have a 50 percent chance to instantly travel to a random plane of existence, avoiding the explosion. If you fail to avoid the effect, you take Force damage equal to 16 times the number of charges in the staff. Each other creature in the area makes a DC 17 Dexterity saving throw. On a failed save, a creature takes Force damage equal to 4 times the number of charges in the staff. On a successful save, a creature takes half as much damage.

Wondrous item, very rare

This book contains coordination and balance exercises, and its words are charged with magic. If you spend 48 hours over a period of 6 days or fewer studying the book’s contents and practicing its guidelines, your Dexterity score increases by 2, as does your maximum for that score. The manual then loses its magic, but regains it in a century.

Rod, uncommon (+1), rare (+2), or very rare (+3) (requires attunement by a warlock)

While holding this rod, you gain a bonus to spell attack rolls and to the saving throw DCs of your warlock spells. This bonus is determined by the rod's rarity.

In addition, you can regain one warlock spell slot as an action while holding the rod. You can't use this property again until you finish a long rest.

Weapon (any sword), legendary (requires attunement)
You gain a +3 bonus to attack and damage rolls made with this magic weapon.

The first time you attack with the sword on each of your turns, you can transfer some or all of the sword’s bonus to your Armor Class, instead of using the bonus on any attacks that turn. For example, you could reduce the bonus to your attack and damage rolls to +1 and gain a +2 bonus to AC. The adjusted bonuses remain in effect until the start of your next turn, although you must hold the sword to gain a bonus to AC from it
