Magic Items

Wand, uncommon The wand has 3 charges. While holding it, you can use an action to expend 1 of its charges, and if a secret door or trap is within 30 feet of you, the wand pulses and points at the one nearest to you. The wand regains 1d3 expended charges daily at dawn.

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.

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. The 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.

Moon Sickle, +1 Weapon (sickle), uncommon (requires attunement by a druid or ranger) When you cast a spell that restores hit points while holding this sickle, a number of ivy leaves equal to the hit points restored sprout from the haft and fall away. This silver-bladed sickle glimmers softly with moonlight. While holding this magic weapon, you gain a bonus to attack and damage rolls made with it, and you gain a +1 bonus to spell attack rolls and the saving throw DCs of your druid and ranger spells. In addition, you can use the sickle as a spellcasting focus for your druid and ranger spells. When you cast a spell that restores hit points, you can roll a d4 and add the number rolled to the amount of hit points restored, provided you are holding the sickle.
