Dungeons & Dragons useful items

What D&D items you find useful?
Hello group! Let’s see how you can handle this question! Saying this just because D&D online huge game, huge battle with bunch of possibilities especially in” weapons” area. It will prolly be tough one to pick one among the million, let’s feel free to exaggerate. Which item in your opinion wins the “most useful” label? Do they fit the character you have chosen to play in the game or yours?

And you are being silent one here, not giving your vote to any item? Playing the judge I guess, lol. Well must confess I am race “swinger”, like to change them not sticking much with one. What can I say, not a faithful soul, hard for me to make a choice. Fact: I am, in a way, nuts about any kind of blades that doesn’t include color green, lol, even though that one in D&D game is a bit coolish But that doesn’t mean that I should be like Highlander that walks through the city and slash heads that stand on his way so could keep on living the eternal life, lol. Very pacifistic unfaithful gamer soul I am.
