A revised Tiefling Artificer pairs the 2024 Tiefling’s legacy spells and resistance with the 2025 Artificer’s Intelligence-based spellcasting and magic-item plans. Choose Abyssal, Chthonic, or Infernal legacy for the defense and spells the campaign needs, then use the background—not species—for ability increases.
Rules edition: Revised 2025 Artificer for 5.5e with the revised 2024 Tiefling. The current Artificer uses Replicate Magic Item plans, not legacy infusions.
Tiefling Artificer Quick Build
| Choice | Recommendation | Why |
|---|---|---|
| Primary ability | Intelligence | Powers Artificer spells and features. |
| Secondary abilities | Constitution, then Dexterity | Support Concentration, Hit Points, Armor Class, and Initiative. |
| Fiendish Legacy | Abyssal, Chthonic, or Infernal by resistance and spell package | Each gives a different defense and level-based magic. |
| Background | An Intelligence-compatible full package | Revised backgrounds supply ability increases and an Origin feat. |
| Subclass | Choose by party role, not ancestry | All five revised subclasses can support the concept. |
Choose the Fiendish Legacy Deliberately
The revised Tiefling can be Small or Medium and chooses Abyssal, Chthonic, or Infernal legacy. The choice determines a damage resistance and a spell progression. Otherworldly Presence supplies Thaumaturgy. Read the current species entry and record the selected legacy on the sheet.
Choose for campaign conditions and action economy. A resistance that regularly applies may contribute more than a spell that competes with the character’s usual action. A species spell can broaden the Artificer without using a preparation, but its casting ability and recharge follow the species feature.
Ability Scores and Background
The revised Tiefling does not provide ability increases. Put the standard array’s 15 in Intelligence, 14 in Constitution, and 13 in Dexterity before the background. Select a background that can improve Intelligence and whose feat, skills, tool, and equipment support the intended role.
Do not import the legacy Tiefling’s old +2 Charisma and +1 Intelligence. Those increases belong to the older species.
Subclass Directions
Alchemist can frame fiendish reagents as something studied and controlled. Armorer creates a strong visual contrast between infernal traits and deliberate protective design. Artillerist supports ranged magical pressure. Battle Smith adds a constructed partner. Cartographer can map planar boundaries and dangerous routes.
Theme does not change mechanics. An infernal-looking Eldritch Cannon, Steel Defender, or replicated item still uses the feature’s printed damage, size, actions, and limits.
Replicate Magic Item Loadout
At Artificer level 2, the revised class learns four plans and creates one or two different replicated items after a Long Rest. Compare those items with the Tiefling’s existing resistance, Darkvision, and spells. Avoid spending a plan on a benefit the character already has unless the item is for an ally.
Attunement matters. A plan that creates a strong item may compete with found treasure. Track plans known, active items, attunement, charges, and carrier separately.
Spell Planning
Separate Tiefling spells from Artificer spells on the sheet. The two sources may use different spellcasting abilities and recovery schedules. Concentration remains one effect at a time regardless of source.
Prepare a role-complete Artificer list: one important Concentration option, one non-Concentration combat option, utility, and support. Fiendish legacy magic should add choices rather than replace the class plan.
Story Without Stereotype
A Tiefling’s fiendish legacy has no required moral outlook. An Artificer might study inherited magic, build tools to control it, treat it as ordinary family history, or reject institutions that mistake ancestry for intent. Define a concrete craft tradition, mentor, customer, or problem instead of making prejudice the character’s only story.
Common Mistakes
- Using old Tiefling ability increases with a revised background.
- Calling the 2025 class’s plans infusions.
- Assuming every Tiefling has Infernal legacy and Fire Resistance.
- Using the Artificer’s Intelligence for a species spell without checking.
- Concentrating on a species spell and class spell simultaneously.
- Changing a device’s damage type because it looks infernal.
