Magic Items

Staff of the Python
Staff, uncommon (requires attunement by a cleric, druid, or warlock)

You can use an action to speak this staff’s command word and throw the staff on the ground within 10 feet of you. The staff becomes a giant constrictor snake under your control and acts on its own initiative count. By using a bonus action to speak the command word again, you return the staff to its normal form in a space formerly occupied by the snake.

On your turn, you can mentally command the snake if it is within 60 feet of you and you aren’t incapacitated. You decide what action the snake takes and where it moves during its next turn, or you can issue it a general command, such as to attack your enemies or guard a location.

If the snake is reduced to 0 hit points, it dies and reverts to its staff form. The staff then shatters and is destroyed. If the snake reverts to staff form before losing all its hit points, it regains all of them.

Tentacle Rod
Rod, rare (requires attunement), Table G

Made by the drow, this rod is a magic weapon that ends in three rubbery tentacles. While holding the rod, you can use an action to direct each tentacle to attack a creature you can see within 15 feet of you.

Each tentacle makes a melee attack roll with a +9 bonus. On a hit, the tentacle deals 1d6 bludgeoning damage. If you hit a target with all three tentacles, it must make a DC 15 Constitution saving throw.

On a failure, the creature's speed is halved, it has disadvantage on Dexterity saving throws, and it can't use reactions for 1 minute. Moreover, on each of its turns, it can take either an action or a bonus action, but not both. At the end of each of its turns, it can repeat the saving throw, ending the effect on itself on a success.
This item can be found on page 208 of the Dungeon Master's Guide.

Armor (Shield), Rare (Requires Attunement)
The convex surface of this shield is a smooth and shiny ebon black. Though plain, it has fine flecks of white that sparkle when exposed to moonlight.
While holding this iron tower shield, you gain a +1 bonus to AC. This bonus is in addition to the shield’s normal bonus to AC.
Additionally, the shield has 3 charges, and it regains 1d3 expended charges daily at dawn. If you are holding the shield and push a creature within your reach at least 5 feet away, you can expend 1 charge to push that creature an additional 10 feet, knock it prone, or both.

Necklace of Prayer Beads
Wondrous item, rare (requires attunement by a cleric, druid, or paladin)

This necklace has 1d4 + 2 magic beads made from aquamarine, black pearl, or topaz. It also has many nonmagical beads made from stones such as amber, bloodstone, citrine, coral, jade, pearl, or quartz. If a magic bead is removed from the necklace, that bead loses its magic.

Six types of magic beads exist. The DM decides the type of each bead on the necklace or determines it randomly. A necklace can have more than one bead of the same type. To use one, you must be wearing the necklace. Each bead contains a spell that you can cast from it as a bonus action (using your spell save DC if a save is necessary). Once a magic bead’s spell is cast, that bead can’t be used again until the next dawn.

Arrow of Dragon Slaying
Weapon (arrow), very rare

An arrow of slaying is a magic weapon meant to slay a particular kind of creature. Some are more focused than others; for example, there are both arrows of dragon slaying and arrows of blue dragon slaying. If a creature belonging to the type, race, or group associated with an arrow of slaying takes damage from the arrow, the creature must make a DC 17 Constitution saving throw, taking an extra 6d10 piercing damage on a failed save, or half as much extra damage on a successful one.

Once an arrow of slaying deals its extra damage to a creature, it becomes a nonmagical arrow.

Other types of magic ammunition of this kind exist, such as bolts of slaying meant for a crossbow, though arrows are most common.
