Artificer (UA)

''Masters of unlocking magic in everyday objects, artificers are supreme inventors. They see magic as a complex system waiting to be decoded and controlled. Artificers use tools to channel arcane power, crafting temporary and permanent magical objects. To cast a spell, an artificer could use alchemist’s supplies to create a potent elixir, calligrapher’s supplies to inscribe a sigil of power on an ally’s armor, or tinker’s tools to craft a temporary charm. The magic of artificers is tied to their tools and their talents.''

You must have a Intelligence score of 13 or higher in order to multiclass in or out of this class.

 * any two simple weapons
 * a light crossbow and 20 bolts
 * (a) studded leather armor or (b) scale mail
 * thieves’ tools and a dungeoneer’s pack

Magical Tinkering
At 1st level, you learn how to invest a spark of magic in objects that would otherwise be mundane. To use this ability, you must have thieves’ tools, tinker’s tools, or other artisan’s tools in hand. You then touch a Tiny nonmagical object as an action and give it one of the following magical properties of your choice: The chosen property lasts indefinitely. As an action, you can touch the object and end the property early.
 * The object sheds bright light in a 5-foot radius and dim light for an additional 5 feet.
 * Whenever tapped by a creature, the object emits a recorded message that can be heard up to 10 feet away. You utter the message when you bestow this property on the object, and the recording can be no more than 6 seconds long.
 * The object continuously emits your choice of an odor or a nonverbal sound (wind, waves, chirping, or the like). The chosen phenomenon is perceivable up to 10 feet away.
 * A static visual effect appears on one of the object’s surfaces. This effect can be a picture, up to 25 words of text, lines and shapes, or a mixture of these elements, as you like.

You can give the magic of this feature to multiple objects, touching one object each time you use the feature, and a single object can bear only one of the properties at a time. The maximum number of objects you can affect with the feature at one time is equal to your Intelligence modifier (minimum of one object). If you try to exceed your maximum, the oldest property immediately ends, and then the new property applies.

Spellcasting
You have studied the workings of magic, how to channel it through objects, and how to awaken it within them. As a result, you have gained a limited ability 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.

Tools Required
You produce your artificer spell effects through your tools. You must have a spellcasting focus—specifically thieves’ tools or some kind of artisan’s tool—in hand when you cast any spell with this Spellcasting feature. You must be proficient with the tool to use it in this way. See chapter 5, “Equipment,” in the  Player’s Handbook  for descriptions of these tools.

After you gain the Infuse Item feature at 2nd level, you can also use any item bearing one of your infusions as a spellcasting focus.

Cantrips
At 1st level, you know two cantrips of your choice from the artificer spell list below. At higher levels, you learn additional artificer cantrips of your choice, as shown in the Cantrips Known column of the Artificer table.

When you gain a level in this class, you can replace one of the artificer cantrips you know with another cantrip from the artificer spell list.

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.

Spellcasting Ability
Intelligence is your spellcasting ability for your artificer spells; your understanding of the theory behind magic allows you to wield these spells with superior skill. You use your Intelligence whenever an artificer spell refers to your spellcasting ability. In addition, you use your Intelligence modifier when setting the saving throw DC for an artificer spell you cast and when making an attack roll with one.

Spell save DC  = 8 + your proficiency bonus + your Intelligence modifier

Spell attack modifier  = your proficiency bonus + your Intelligence modifier

Ritual Casting
You can cast an artificer spell as a ritual if that spell has the ritual tag and you have the spell prepared.

Infuse Item
At 2nd level, you gain the ability to imbue mundane items with certain magical infusions. The magic items you create with this feature are effectively prototypes of permanent items.

Infusions Known
When you gain this feature, pick three artificer infusions to learn, choosing from the list of Artificer Infusions. You learn additional infusions of your choice when you reach certain levels in this class, as shown in the Infusions Known column of the Artificer table.

Whenever you gain a level in this class, you can replace one of the artificer infusions you learned with a new one.

Infusing an Item
Whenever you finish a long rest, you can touch a nonmagical object and imbue it with one of your artificer infusions, turning it into a magic item. An infusion works on only certain kinds of objects, as specified in the infusion’s description. If the item requires attunement, you can attune yourself to it the instant you infuse the item, or you can forgo attunement so that someone else can attune to the item. If you decide to attune to the item later, you must do so using the normal process for attunement (see “Attunement” in the Dungeon Master’s Guide, page 136).

Your infusion remains in an item indefinitely, but when you die, the infusion vanishes after a number of days have passed equal to your Intelligence modifier (minimum of 1 day). The infusion also vanishes if you give up your knowledge of the infusion for another one.

You can infuse more than one nonmagical object at the end of a long rest; the maximum number of objects appears in the Infused Items column of the Artificer table. You must touch each of the objects, and each of your infusions can be in only one object at a time. If you try to exceed your maximum number of infusions, the oldest infusion immediately ends, and then the new infusion applies.

Artificer Specialist
At 3rd level, you choose the type of specialist you are:
 * Alchemist
 * Archivist
 * Artillerist
 * Battle Smith

Tool Expertise
Starting at 3rd level, your proficiency bonus is doubled for any ability check you make that uses your proficiency with a tool.

Ability Score Improvement
When you reach 4th, 8th, 12th, 16th, and 19th level, you can increase one ability score of your choice by 2, or you can increase two ability scores of your choice by 1. As normal, you can’t increase an ability score above 20 using this feature.

Using the optional feats rule, you can forgo taking this feature to take a feat of your choice instead.

Arcane Armament
Starting at 5th level, you can attack twice, rather than once, whenever you take the Attack action on your turn, but one of the attacks must be made with a magic weapon, the magic of which you use to propel the attack.

The Right Cantrip for the Job
At 10th level, you gain the ability to make sure you have the right magical tool for a job. Whenever you finish a short or long rest, you can replace one of the artificer cantrips you know with another cantrip from the artificer spell list.

Spell-Storing Item
When you reach 18th level, you learn how to store a spell in an object for repeated use. Whenever you finish a long rest, you can touch one simple or martial weapon or an item that you can use as a spellcasting focus and store a spell in it, choosing one 1st- or 2nd-level spell from the artificer spell list that requires 1 action to cast (you don’t need to have the spell prepared). With the object in hand, a creature can take an action to produce the spell’s effect from it, using your spellcasting ability modifier.

The spell stays in the object until it has been used a number of times equal to twice your Intelligence modifier (minimum of twice) or until you use this feature again.

Soul of Artifice
At 20th level, your understanding of magic items is unmatched, allowing you to mingle your soul with items linked to you. You can attune to up to six magic items at once. In addition, you gain a +1 bonus to all saving throws per magic item you are currently attuned to.
