Magic items are gleaned from the hoards of conquered monsters or discovered in long-lost vaults. Such items grant capabilities a character could rarely have otherwise, or they complement their owner's capabilities in wondrous ways.
Each magic item has a rarity: common, uncommon, rare, very rare, or legendary. Common magic items, such as a potion of healing, are the most plentiful. Some legendary items, such as the apparatus of Kwalish, are unique. The game assumes that the secrets of creating the most powerful items arose centuries ago and were then gradually lost as a result of wars, cataclysms, and mishaps. Even uncommon items can't be easily created. Thus, many magic items are well-preserved antiquities.
Rarity provides a rough measure of an item's power relative to other magic items.
Some magic items are indistinguishable from their nonmagical counterparts, whereas other magic items display their magical nature conspicuously. Whatever a magic item's appearance, handling the item is enough to give a character a sense that something is extraordinary about it. Discovering a magic item's properties isn't automatic, however.
The identify spell is the fastest way to reveal an item's properties. Alternatively, a character can focus on one magic item during a short rest, while being in physical contact with the item. At the end of the rest, the character learns the item's properties, as well as how to use them. Potions are an exception; a little taste is enough to tell the taster what the potion does.
Sometimes a magic item carries a clue to its properties. The command word to activate a ring might be etched in tiny letters inside it, or a feathered design might suggest that it's a ring of feather falling.
Wearing or experimenting with an item can also offer hints about its properties. For example, if a character puts on a ring of jumping, you could say, "Your steps feel strangely springy." Perhaps the character then jumps up and down to see what happens. You then say the character jumps unexpectedly high.
If you prefer magic items to have a greater mystique, consider removing the ability to identify the properties of a magic item during a short rest, and use the following rules instead:
Magic Item Identification. Players may attempt to identify a magic item without the benefit of the Identify spell, but rather than the default assumption (spending time with the item during a short rest), this is done by making an Arcana check and consulting the following table. If the character is not Proficient in Arcana, the check is made with Disadvantage.
| DC | Result |
| 10 | The character is confident the item is magical, but is unable to ascertain its nature. |
| 15 | The Character is able to guess the rough properties of the item, and may attempt to use it. However they do not know how many charges it has, and may not necessarily be able to work out the command word if it has one. More likely he or she knows what will happen when the command word is uttered, but will need another Arcana roll (once per rest) to correctly guess what it is. |
| 20 | The Character recognizes the item and after a short period of experimentation (a short rest) is able to use its full powers. |
| 25 | The Character recognizes the item and can use its full powers immediately. If the item requires Attunement, they may attune to the item straight away. (Also use this result on a roll of a Natural 20). |
In order for a magic item to function properly it must be worn or wielded as the item intended: feet in boots, hands in gloves, heads under hats or inside helmets, fingers in rings. Magic armors and shields only work when they are donned, weapons have to be wielded, and cloaks fastened around a creature’s shoulders.
Unless noted otherwise, a worn magic item automatically stretches or shrinks to match the size and shape of the creature wearing it. When a nonhumanoid creature attempts to wear a magic item, it’s up to the Narrator whether it works or not—a merfolk can certainly use rings and amulets, but probably not a pair of enchanted boots.
Most creatures have only two legs and one head so usually a creature can only make use of a single pair of boots and one hat or helmet. Whether or not more than one item can be worn in the same spot is at the Narrator’s discretion. For example, an ettin (which has two heads) might be able to wear two magic hats, or a half-elven mage may be allowed to wear a magic circlet beneath an enchanted helmet.
When a magic item is described as a pair—boots, bracers, gauntlets, gloves—any properties it grants only function when the full set is worn. For example, an adventurer wearing one half of bracers of defense and one half of bracers of archery doesn’t gain the benefits of wearing either.
Some magic items require a creature to form a bond with them before their magical properties can be used. This bond is called attunement, and certain items have a prerequisite for it. If the prerequisite is to be a spellcaster, a creature qualifies if it can cast at least one spell using its traits or features, not using a magic item or the like. (If the class is a spellcasting class, a monster qualifies if that creature has spell slots and uses that class's spell list.)
Without becoming attuned to an item that requires attunement, a creature gains only its nonmagical benefits, unless its description states otherwise. For example, a magic shield that requires attunement provides the benefits of a normal shield to a creature not attuned to it, but none of its magical properties.
Attuning to an item requires a creature to spend a short rest focused on only that item while being in physical contact with it (this can't be the same short rest used to learn the item's properties). This focus can take the form of weapon practice (for a weapon), meditation (for a wondrous item), or some other appropriate activity. If the short rest is interrupted, the attunement attempt fails. Otherwise, at the end of the short rest, the creature gains an intuitive understanding of how to activate any magical properties of the item, including any necessary command words.
An item can be attuned to only one creature at a time, and a creature can be attuned to no more than three magic items at a time. Any attempt to attune to a fourth item fails; the creature must end its attunement to an item first. Additionally, a creature can't attune to more than one copy of an item. For example, a creature can't attune to more than one ring of protection at a time.
A creature's attunement to an item ends if the creature no longer satisfies the prerequisites for attunement, if the item has been more than 100 feet away for at least 24 hours, if the creature dies, or if another creature attunes to the item. A creature can also voluntarily end attunement by spending another short rest focused on the item, unless the item is cursed.
There are magic items that require something special to function, like speaking a command word while holding it. Each magic item’s description provides details on how it is activated, otherwise using the following rules.
Note that the Use an Item action does not apply to magic items—any item that requires an action to activate is treated as its own separate action, not the Use an Item action.
Magic items often have charges which must be expended to activate one or more of their properties. How many charges the magic item has is revealed either when a creature attunes to it or after a casting of the identify spell. In addition, when an attuned magic item regains charges the creature attuned to it knows how many charges have been regained.
Command words are specific words or phrases that when spoken cause a magic item to use one of its properties. Magic items that require a command word to be spoken can’t be activated in the area of a silence spell or other circumstance where sound is prevented.
Magic items can also be used up when activated—elixirs and potions have to be swallowed, oils applied to an item or creature’s body, arcane or divine script disappearing as it is read from a spell scroll, and so on. A consumable magic item loses its magic after being used.
Many magic items grant the creature using them the ability to cast one or more spells. Unless stated otherwise, a spell cast from a magic item is cast at the lowest possible spell level, and it requires no components or spell slots. The spell uses its normal rules unless the item describes a change to how the spell functions, and if it requires concentration the creature must maintain concentration on the spell. Some magic items (like potions) simply grant the benefits of a spell, with its usual duration, without requiring the spell be cast or for the creature to concentrate.
When a staff or other magic item requires a creature to use its own spellcasting ability and it has more than one spellcasting ability, it chooses which to use. A creature without a spellcasting ability that uses such an item cannot use its proficiency bonus and it treats its spellcasting ability modifier as +0.
Some magic items bear curses that bedevil their users, sometimes long after a user has stopped using an item. A magic item's description specifies whether the item is cursed. Most methods of identifying items, including the identify spell, fail to reveal such a curse, although lore might hint at it. A curse should be a surprise to the item's user when the curse's effects are revealed.
Attunement to a cursed item can't be ended voluntarily unless the curse is broken first, such as with the remove curse spell.
Some magic items possess sentience and personality. Such an item might be possessed, haunted by the spirit of a previous owner, or self-aware thanks to the magic used to create it. In any case, the item behaves like a character, complete with personality quirks, ideals, bonds, and sometimes flaws. A sentient item might be a cherished ally to its wielder or a continual thorn in the side.
Most sentient items are weapons. Other kinds of items can manifest sentience, but consumable items such as potions and scrolls are never sentient.
Sentient magic items function as NPCs under the DM's control. Any activated property of the item is under the item's control, not its wielder's. As long as the wielder maintains a good relationship with the item, the wielder can access those properties normally. If the relationship is strained, the item can suppress its activated properties or even turn them against the wielder.
