You have studied the workings of magic, how to channel it through objects, and how to awaken it within them. By the time you reach 2nd levei, you hhave learned to invoke magic to cast spells. To observers, you don’t appear to be casting spells in a conventional way; you look as if you’re producing wonders through various items.

Preparing and Casting Spells

The Artificer table shows how many spell slots you have to cast your artificer spells. To cast one of your artificer spells of 1st level or higher, you must expend a slot of the spell’s level or higher. You regain all expended spell slots when you finish a long rest.

You prepare the list of artificer spells that are available for you to cast, choosing from the artificer spell list. When you do so, choose a number of artificer spells equal to your Intelligence modifier + half your artificer level, rounded down (minimum of one spell). The spells must be of a level for which you have spell slots.

For example, if you are a 5th-level artificer, you have four 1st-level and two 2nd-level spell slots. With an Intelligence of 14, your list of prepared spells can include four spells of 1st or 2nd level, in any combination. If you prepare the 1st-level spell cure wounds, you can cast it using a 1st-level or a 2nd-level slot. Casting the spell doesn’t remove it from your list of prepared spells.

You can change your list of prepared spells when you finish a long rest. Preparing a new list of artificer spells requires time spent in tinkering with your spellcasting focuses: at least 1 minute per spell level for each spell on your list.
