Background Feature: Survival Instincts
Having survived for some years, you are able to make simple survival necessities. You can make fires, craft shelters, cook food, etc. without having to make a Survival check. Also, you may know several townspeople, hunters, and shop owners from your travels alone. Landmarks and places of interest may also be familiar to you.
Magical Tinkering
At 1st level, you've learned how to invest a spark of magic into mundane objects. To use this ability, you must have thieves' tools or 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 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.
The chosen property lasts indefinitely. As an action, you can touch the object and end the property early.

You can bestow magic on multiple objects, touching one object each time you use this feature, though a single object can only bear one property at a time. The maximum number of objects you can affect with this 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've studied the workings of magic and how to cast spells, channeling the magic through objects. To observers, you don't appear to be casting spells in a conventional way; you appear to produce wonders from mundane items and outlandish inventions.

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 (meaning the spell has an "M" component when you cast it). You must be proficient with the tool to use it in this way. See the equipment chapter 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 (0-Level Spells)
At 1st level, you know two cantrips of your choice from the artificer spell list. 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.

You can change your list of prepared spells when you finish a long rest. Preparing a new list of artificer spells requires time spent 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've gained the ability to imbue mundane items with certain magical infusions, turning those objects into magic items.

Infusions Known
When you gain this feature, pick four artificer infusions to learn. 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. If you decide to attune to the item later, you must do so using the normal process for attunement (see the attunement rules in the Dungeon Master's Guide).

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

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. Moreover, no object can bear more than one of your infusions at a time. If you try to exceed your maximum number of infusions, the oldest infusion ends, and then the new infusion applies.

If an infusion ends on an item that contains other things, like a bag of holding, its contents harmlessly appear in and around its space.

Artificer Specialist
At 3rd level, you choose the type of specialist you are. Your choice grants you features at 5th level and again at 9th and 15th level.: Artificer: Mastermaker
Tools of Integration
At 3rd level, you gain proficiency with heavy armor and smith’s tools. If you already have this tool proficiency, you gain proficiency with one other type of artisan’s tools of your choice.

Mastermaker Spells
At 3rd level, you always have certain spells prepared after you reach particular levels in this class, as shown in the Mastermaker Spells table. These spells count as artificer spells for you, but they don’t count against the number of artificer spells you prepare.

Mastermaker Spells
Artificer Level Spells
3rd Absorb Elements, Thunderous Smite
5th Enhance Ability, Lesser Restoration
9th Blinding Smite, Haste
13th Freedom of Movement, Stone Shape
17th Banishing Smite, Greater Restoration
Prosthesis Expertise
At 3rd level, whenever you finish a long rest, you can touch a nonmagical object and imbue it with your power, creating a permanent magical item that replaces a lost limb—a hand, arm, foot, leg, or similar body part. While the prosthetic is attached, it functions identically to the part it replaces. The wearer can detach or reattach it as an action, and it can’t be removed against the wearer’s will. It detaches if the wearer dies.
________________________________________________________________________________________________________________________________
Battlefist
At 3rd level you replace one of your arms with a battlefist, a magical prosthetic you created. Your battlefist is a simple melee weapon, and you can use it as a spellcasting focus for your artificer spells. While your battlefist is a magical weapon, it can be infused as if it were a nonmagical weapon.

When you attack with your battlefist, you can use your Intelligence modifier instead of Strength for the attack roll. If you hit with it, you deal bludgeoning damage equal to 1d10 + your Strength or Intelligence modifier. At 9th level, the damage dealt by your battlefist increases to 2d10 + your Strength or Intelligence modifier.

Additionally, you can choose one of the following weapon properties to add to your battlefist: finesse, thrown (range 20/60), or reach. When you finish a long rest, you can replace this property with a different weapon property from the list.

Extra Attack
At 5th level, you can attack twice, rather than once, whenever you take the Attack action on your turn.

Improved Battlefist
At 9th level, you have modified your battlefist in both mundane and magical ways. It gains the following benefits:

When you infuse your battlefist, you can apply two infusions to it at a time. If both infusions grant bonuses to your attack rolls or armor class, you gain only the greater bonus.
Your battlefist is also a shield, increasing your armor class by 2. You can wield it as a weapon even if you are using it as a shield. You can infuse it as if it were both a simple melee weapon and a shield.
The maximum number of items you can infuse at once increases by 1, but the extra infusion must be applied to your battlefist.
Construct Apotheosis
At 15th level you have modified your form, becoming nearly impervious to the weaknesses of flesh. You gain the following benefits:

You gain resistance to poison damage and psychic damage, and you are immune to the poisoned condition.
If you are affected by a spell or magical effect, you can choose to consider yourself a construct instead of your other creature types.
You can cast the Antilife Shell and Investiture of Stone spells without expending a spell slot, without preparing the spell, and without material components, provided you use your battlefist as the spellcasting focus. Once you cast either spell with this feature, you can’t cast that spell with it again until you finish a long rest.

The Right Tool for the Job
At 3rd level, you've learned how to produce exactly the tool you need: with thieves' tools or artisan's tools in hand, you can magically create one set of artisan's tools in an unoccupied space within 5 feet of you. This creation requires 1 hour of uninterrupted work, which can coincide with a short or long rest. Though the product of magic, the tools are nonmagical, and they vanish when you use this feature again.

Ability Score Improvement
When you reach 4th level, 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.

Tool Expertise
At 6th level, your proficiency bonus is now doubled for any ability check you make that uses your proficiency with a tool.

Flash of Genius
At 7th level, you've gained the ability to come up with solutions under pressure. When you or another creature you can see within 30 feet of you makes an ability check or a saving throw, you can use your reaction to add your Intelligence modifier to the roll.

You can use this feature a number of times equal to your Intelligence modifier (minimum of once). You regain all expended uses when you finish a long rest.

Magic Item Adept
When you reach 10th level, you achieve a profound understanding of how to use and make magic items:

You can attune to up to four magic items at once.
If you craft a magic item with a rarity of common or uncommon, it takes you a quarter of the normal time, and it costs you half as much of the usual gold.
Spell-Storing Item
At 11th level, you can now store a spell in an object. Whenever you finish a long rest, you can touch one simple or martial weapon or one item that you can use as a spellcasting focus, and you store a spell in it, choosing a 1st- or 2nd-level spell from the artificer spell list that requires 1 action to cast (you needn't have it prepared).

While holding the object, a creature can take an action to produce the spell's effect from it, using your spellcasting ability modifier. If the spell requires concentration, the creature must concentrate. The spell stays in the object until it's been used a number of times equal to twice your Intelligence modifier (minimum of twice) or until you use this feature again to store a spell in an object.

Magic Item Savant
At 14th level, your skill with magic items deepens more:

You can attune to up to five magic items at once.
You ignore all class, race, spell and level requirements on attuning to or using a magic item.
Magic Item Master
Starting at 18th level, you can attune up to six magic items at once.

Soul of Artifice
At 20th level, you develop a mystical connection to your magic items, which you can draw on for protection:

You gain a +1 bonus to all saving throws per magic item you are currently attuned to.
If you're reduced to 0 hit points but not killed out-right, you can use your reaction to end one of your artificer infusions, causing you to drop to 1 hit point instead of 0.
