Etherealness is a beast of a spell; getting access to it, even for just a short time, can lead to some spectacular plans and escapes. This oil is worth investing in if you can afford it. 

If you’re in need of a cleric, short of solving death, a Necklace of Prayer beads may be a fine replacement. Most of the effects it produces do a pretty close approximation to a mid-level cleric, and while most of the time it's a Bless and Cure Wounds stick, it still has some potential to majorly boost your team’s survival rates. 

The Barbarian class is just begging for anything interesting at all to make it worth playing. A few of the subclasses kinda help in that department, but nothing besides multiclassing will truly fix that problem. As a DM, you can alleviate some of these issues with the proper magic items.

The Artificer has a very unique relationship with magic items. They are able to create their own magic items, both unique ones through infusions and also replicating existing magic items through the Replicate Magic Item infusion.

This may say it's a necklace, but in reality this is a bazooka. You’re packing grenades you can pick off and throw out as needed. It's a tool of mass destruction masquerading as jewelry. 

Simple, clean, effective; the Mantle of Spell Resistance is the kind of item basically every character can benefit from.

The Mace of Terror does a fantastic job being spooky. You slam it down, and everything around is going to have a bad time while fleeing aimlessly from you. Metal! 

Constructs beware- the Mace of Smiting is here to blow you to pieces. Why smiting deals bonus damage to constructs is a bit odd to me, but hey, it's going to be fantastic against those golems who take forever to break through! 

Simple, pure undead destruction. I love me some Disruption. This mace has historically smashed in skeleton skulls since back in 2nd edition, and to this day it does the job when it comes to undead demoralization. 

These little tangling bands are a handy trick to keep on hand for picking one baddy you’d rather restrain than engage with. You don’t want something to pass the ability check, but if they don’t and stay bound, this thing is a game changer. 

This is basically a subset of items that have their own little mini-game- they’re sweet. If you want a boon attached to an item you don’t have to wear, these stones will often be exactly what you’re looking for.

Are you tired of your warhorse only having 60 ft. speed? Pick up some Horseshoes of Speed!

There are few things as iconic to Valhalla as swarms of viking spirits, and that’s exactly what this horn summons for you. With a toot toot, you can conjure into existence berserkers for an hour once every seven days, with increasing numbers. Insane!

Sometimes you need a big blast to break your enemies to pieces; a Horn of Blasting is an easy way to get there, but at a tremendous risk. Still, sometimes you’ve got no other options, or are facing a swarm of glass monsters, and in those moments, it’ll (hopefully) work out! 

There are few items as wonderful to play with as a Helm of Teleportation; go where you want, when you want, up to three times per day. What’s not to love?

While it may seem innocent enough, a Handy Haversack is one of the cheapest, most destructive forces you can seek out. Its interactions with common items make it a kind of black hole in a box that can tactically decimate a creature with no save to dodge it.

Mundane studded leather armor isn’t the look for me. It's plain, boring, practical- I need my look to be flashy. If you’re a ranger in need of a better social life, consider a single item that’s a complete, infinite wardrobe for all your presentation needs! 

For the best chance of taking down an ancient storm giant, you should come with a Giant Slayer. It's in the name. These things will juice your attacks to slay the grandest giant monsters. 

Are pesky illusions getting you down? Have you been swindled three times this week by fake jewelry? You need a Gem of Seeing! 

Folding Boat implies it's a mere single boat that folds up, like an inflatable dingy; you better get Billy Mays on the phone, 'cause wait, there’s more! Not only does it transform into a rowboat, it also turns into a freaking 24 ft. long viking-esque ship!
