Rules edition: This guide uses the legacy Half-Elf from the 2014 Basic Rules and the Artificer rules in Tasha’s Cauldron of Everything. The Artificer is a later class option, and the legacy Half-Elf is not the revised 2024 Elf species. Optional origin customization is discussed separately; use it only if the DM allows it.
A Half-Elf Artificer pairs flexible ability scores and extra skill proficiencies with Intelligence-based invention. The ancestry does not grant special tool checks or make the character a better Artificer automatically. Use the score increases to support the class, then choose a specialist for the campaign role you want.
Legacy Half-Elf traits
The 2014 Half-Elf increases Charisma by 2 and two other ability scores of your choice by 1 each. It also has 60-foot Darkvision, Fey Ancestry, and Skill Versatility, which grants proficiency in two skills. Fey Ancestry gives advantage on saving throws against being charmed, and magic cannot put you to sleep; it does not provide blanket immunity to charm effects.
With Tasha’s optional origin customization, you may use its ability-score and proficiency replacement rules instead of the fixed legacy increases. Do not combine both versions. The campaign’s source and character-creation rules decide which option applies.
Ability scores and a legal point-buy example
With 27-point buy, one workable array before ancestry bonuses is Strength 8, Dexterity 14, Constitution 13, Intelligence 15, Wisdom 10, and Charisma 12. That costs 27 points. Put one Half-Elf increase in Constitution and one in Intelligence for Constitution 14 and Intelligence 16; the +2 Charisma increase makes Charisma 14. The resulting scores are Strength 8, Dexterity 14, Constitution 14, Intelligence 16, Wisdom 10, and Charisma 14.
Intelligence is the Artificer’s spellcasting ability and is used by features that specifically refer to your Artificer spellcasting ability. Constitution supports hit points and concentration. Dexterity helps AC in medium armor, up to the armor’s limit. Charisma 14 can support social skills, but the class does not require it.
Tools and Artificer checks
The Tasha’s Artificer is proficient with thieves’ tools, tinker’s tools, and one type of artisan’s tools of your choice. Tool proficiency lets you add your proficiency bonus when the DM calls for an ability check using a tool you are proficient with. It does not mean every tool check automatically uses Intelligence: the DM chooses the ability that fits the task, and a check can combine an ability with a relevant tool proficiency.
At 6th level, Tool Expertise doubles your proficiency bonus for checks using a tool proficiency you have. This is a specific class feature; it is not a Half-Elf trait and does not apply to every Intelligence check.
Spellcasting and infusions
Artificers prepare spells after a long rest. The number is your Intelligence modifier plus half your Artificer level, rounded down, with a minimum of one. Intelligence sets your Artificer spell save DC and spell attack modifier. Prepared spells, spell slots, and the level at which you gain access to each slot follow the Tasha’s Artificer table.
At Artificer level 2, you know four infusion options and can have two infused items active at once. These are separate limits: you cannot make all four known infusions active at the same time. The class table increases both limits later. Each infusion has its own prerequisites, eligible item, and restrictions, so choose options your character can actually use.
Concentration spells such as web, heat metal, and haste compete with one another: you can maintain only one concentration spell at a time. A Battle Smith’s Steel Defender and an Artillerist’s Eldritch Cannon also compete for bonus actions when their features call for one.
Choose an Artificer specialist
Battle Smith: Battle Ready lets you use Intelligence for attack and damage rolls with magic weapons. The Steel Defender takes its turn after yours; unless you use a bonus action to command it to take another action, it takes the Dodge action. Its Deflect Attack reaction can interfere with an attack against a nearby creature. At 9th level, Arcane Jolt can add damage when you or the Defender hits, or restore hit points under the feature’s conditions. It does not grant a reaction attack.
Artillerist: The Eldritch Cannon has a damaging mode or a Protector mode that grants temporary hit points. The cannon’s mode, attack, range, and action use follow its feature text. At 9th level, Explosive Cannon adds to its damage and lets you detonate it under the feature’s conditions. The Half-Elf’s skills do not grant any special ability to build or disguise a cannon.
Armorer: Arcane Armor is made from armor you are wearing and gains the model’s features. The subclass grants heavy armor proficiency, and the Arcane Armor feature waives that armor’s normal Strength requirement for you. Guardian and Infiltrator have different attacks and roles; the armor does not give every model the same benefits.
Alchemist: Experimental Elixir offers specific effects and uses, while Alchemical Savant applies only in its stated circumstances. Read the feature’s level, spell, tool, and damage-type conditions rather than assuming all healing or damage benefits from it.
Feats and practical choices
Resilient (Constitution) can improve Constitution saves, including concentration saves, if it fits your score. War Caster grants advantage on concentration saves and has separate benefits for somatic components and opportunity-attack spells. Its spell option only permits a spell with a casting time of 1 action that targets only the creature provoking the opportunity attack.
Choose a background for its actual skill, tool, and story benefits. Guild Artisan, Sage, or another background can fit a character who studies or builds magical devices, but no background automatically grants access to recipes, rare materials, or a permanent workshop. Those details depend on the campaign.
Roleplaying a Half-Elf inventor
Skill Versatility can help the character participate in exploration or social scenes, but it need not define their personality. Decide what they want to make, who taught them, and what problem they hope to solve. Their family history can shape the character without determining their values or requiring them to serve as the party face.
