Reanimator

Most artificers prefer to work with chemicals or metals, but you work with flesh and bone. Other artificers are known to push boundaries in pursuit of magical advancement, but you transgress even those limits. These differences have resulted in your unique ability to manipulate the states of life and death. Others may believe these states are static, but to a reanimator they are dynamic—what is living may die, and what is dead may live again.

Level 3: Tools of the Trade

You gain the following benefits.

Tool Proficiency. You gain proficiency with Alchemist's Supplies. If you already have this proficiency, you gain proficiency with one other type of Artisan’s Tools of your choice. 

Surgeon's Studies. You gain proficiency with the Medicine skill, and add your Intelligence modifier when making a Wisdom (Medicine) check. You can use a Healer's Kit as a spellcasting focus for your Artificer spells.

Potion Crafting. When you brew a potion using the crafting rules in the Dungeon Master’s Guide, the amount of time required to craft it is halved.

Level 3: Reanimator Spells

When you reach an Artificer level specified in the Reanimator Spells table, you thereafter always have the listed spells prepared.

Reanimator Spells

Artificer Level	Prepared Spells
3	Cure Wounds, Witch Bolt
5	Gentle Repose, Hold Person
9	Call Lightning, Revivify
13	Storm Sphere, Summon Construct
17	Danse Macabre, Raise Dead

Level 3: Modern Prometheus

Your transgressive experiments with life after death have borne fruit, and you have created a composite golem. It’s friendly to you and your companions and obeys your commands. See its game statistics in the Composite Golem stat block, which uses your proficiency bonus (PB) in several places. Your composite golem is covered in the stitches and staples necessary to keep the various body parts it’s composed of attached to one another.

In combat, the golem shares your initiative count, but it takes its turn immediately after yours. It obeys your verbal commands (no action required by you). If you don’t issue any, it takes the Dodge action and uses its move to avoid danger. If you are incapacitated, the golem can take any action of its choice, not just Dodge. If the mending spell is cast on it, it regains 2d6 hit points. If it has died within the last hour, you can use a healer's kit as an action to revive it, provided you are within 5 feet of it and you expend a spell slot of 1st level or higher. The golem returns to life after 1 minute with all its hit points restored.

At the end of a long rest, you can create a new composite golem if you have a healer's kit and spare parts with you. If you already have a golem from this feature, the first one immediately perishes. The composite golem also perishes if you die.

Level 3: Macabre Modules

Also at 3rd level, you can upgrade your composite golem in your idle time. When you finish a long rest, choose two macabre modules from the list below. Your golem gains the benefit of these modules until you use this feature again. Starting at 9th level, you can choose three macabre modules when you finish a long rest. 

Adamant Staples

Your composite golem’s weapon attacks count as magical for the purposes of overcoming damage resistances. In addition, the golem has resistance to damage from critical hits.

Beastial Components

Your composite golem incorporates animal components to enhance its abilities. While this module is installed, your golem’s base movement speed increases by 10 feet, it has advantage on Wisdom (Perception) ability checks that rely on scent, and it has darkvision out to a distance of 120 feet.

Electric Touch

Your composite golem can cast the shocking grasp cantrip. When it casts this cantrip, it uses your spell attack modifier, counts as your level for the purposes of the cantrip’s damage scaling, and scores a critical hit on a result of 19 or 20 on the attack roll.

Growth Hormone

Your composite golem’s size increases to Large. Its maximum hit points increase by 2 per level you have in this class.

Iron Knuckles

When your composite golem hits a creature with a slam attack, that creature must succeed on a Strength saving throw with a DC of your artificer spell save DC or be pushed 5 feet or knocked prone (your choice).

Level 5: Enlivening Discharge

At 5th level, when your composite golem is within 60 feet of you, you can use an action to fire a bolt of empowering energy at it. When you do, it gains the following benefits for the next minute:

• It gains resistance to bludgeoning, piercing, and slashing damage.
• It regains a number of hit points equal to your Proficiency Bonus at the start of each of its turns.
• Its slam attack deals an additional 1d10 lightning damage.

 Once you use this feature, you can’t use it again until you finish a short or long rest.

Level 9: Reanimate Dead

At 9th level, you always have the animate dead spell prepared and can cast it without expending a spell slot. It counts as an artificer spell for you and does not count against the maximum number of spells you can prepare. When you cast the spell, the creature type of the skeletons or zombies created changes from undead to construct and has resistance to lightning damage.

Once you cast this spell without expending a spell slot, you cannot do so again until you finish a long rest.

In addition, whenever you create a construct with a spell, one can be created with a macabre module of your choice. Only one construct other than your Composite Golem can have a macabre module at any given time.

Level 15: Spark of Life

Starting at 15th level, your understanding of the role that electricity has in starting and stopping life has led to improved outcomes. When you cast an artificer spell that restores hit points or deals lightning damage, roll 2d6 and add the result to the amount healed or lightning damage dealt by the spell.
