Magic Items

Wonderous item, uncommon (requires attunement by a spellcaster)
While this pearl is on your person, you can use an Action to speak its Command word and regain one expended spell slot. If the expended slot is of 4th Level or higher, the new slot is 3rd Level. Once you have used the pearl, it can't be used again until the next dawn.
This item also has the "Beacon" property, which means the bearer can use a bonus action to cause the pearl to shed bright light in a 10-foot radius and dim light for an additional 10 feet, or to extinguish the light.
This item is found in chapter 7 of the Dungeon Master’s Guide.
It looks like a lustrous silvery-blue pearl that’s about the size of a pebble.

Staff, Uncommon (Requires Attunement)
As a Magic action, you can throw this staff so that it lands in an unoccupied space within 10 feet of you, causing the staff to become a Giant Constrictor Snake in that space. The snake is under your control and shares your Initiative count, taking its turn immediately after yours.
On your turn, you can mentally command the snake (no action required) if it is within 60 feet of you and you don’t have the Incapacitated condition. You decide what action the snake takes and where it moves during its turn, or you can issue it a general command, such as to attack your enemies or guard a location. Absent commands from you, the snake defends itself.
As a Bonus Action, you can command the snake to revert to staff form in its current space, and you can’t use the staff’s property again for 1 hour. 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.

You have a +1 bonus to attack and damage rolls made with this magic weapon.

Rod, uncommon (requires attunement by a warlock)

While holding this rod, you gain a +1 bonus to spell attack rolls and to the saving throw DCs of your warlock spells.

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.
