Weapons are some of the most prolific magic items in D&D 5e. The game has many swords, daggers, and more with spectacular additional effects. However, a plain +1 weapon is often all a character needs.
Few D&D 5e magic weapons benefit a Hexblade warlock as much as a Scimitar of Speed. The Broom of Flying is a classic spellcaster magic item that allows characters to fly through the air.
