I built Jaxen because Armorer Artificer is the cleanest official way for me to turn the Iron Man idea into a fantasy character. The part I wanted most was the self-made armor: a smart character who solves problems with preparation, tools, and a suit that changes how he fights.
Jaxen is still a concept build, not an active campaign character. I wanted the baseline to stay practical at level 3, so this version assumes equipment he can reasonably have from ordinary play rather than an idealized late-campaign loadout.

What I wanted from the build
The build only needed a few defining pieces.
- Arcane armor that feels like the character’s signature invention.
- A durable front-line mode that can protect allies instead of only blasting from range.
- Spells and infusions that read like gadgets without pretending every single effect is a separate suit.

Attacks and key features
| Feature or attack | Value | Notes |
|---|---|---|
| Thunder Gauntlets | +5 to hit, 1d8 + 3 thunder | Uses Intelligence |
| Defensive Field | 3 temporary hit points | Bonus action, 2 uses per long rest |
| Arcane Armor | Official armorer feature | Lets the armor function as the suit concept |
I am keeping Guardian as the baseline at level 3. It fits the protective version of the Iron Man concept better than the Infiltrator model for this draft.
Why I chose these options
The main correction here was keeping Jaxen legal at level 3 instead of writing as if he already had later-level flexibility.
Scale mail and shield are the safe assumptions because they are ordinary for an artificer and do not depend on finding expensive armor early. With Dexterity 14 and Enhanced Defense, that gives him AC 19 without inventing extra gear.
I also separated infusions into three groups: what he knows, what he can actively maintain, and what he might keep in reserve. At level 3 he knows four infusions but can only keep two infused items active, and Arcane Armor does not split into separately infusable pieces until level 9.
How the character plays
Jaxen is a durable front-line artificer with a defensive bias.
- Normal combat approach: start in Guardian armor, attack with Thunder Gauntlets, and pressure a target so it has disadvantage on attacks against anyone except Jaxen.
- Defensive options: AC 19, Shield, Absorb Elements, and Defensive Field for a small buffer of temporary hit points.
- Exploration and social utility: artificer tools, Detect Magic, Mage Hand, and Guild Artisan background skills make him more useful outside combat than Tharn.
- Action-economy limit: using Defensive Field costs the same bonus action pool that other class features or items might want later, so it is not free protection every round.
- What the build cannot do: it does not have flight, multiple armor configurations in one fight, or high-level suit customization yet.
Official rules, reflavouring, and homebrew
Official mechanics
- Half-Elf with Tasha’s ability-score reassignment
- Artificer and Armorer from Tasha’s Cauldron of Everything
- Guardian armor model, Thunder Gauntlets, standard artificer spellcasting and infusions
Reflavouring
- The armor is Jaxen’s “suit” in the Iron Man sense.
- Spells and infusions are presented as built-in gadgets, shielding systems, and calibration tools.
Optional homebrew
This build does not need homebrew in its main version.
Progression
The next useful decisions are close by.
- Level 4: increase Intelligence to 18.
- Level 5: Extra Attack makes Guardian feel much more complete as a front-line armor build.
Current status
Jaxen is still a concept build I wanted to make coherent and table-ready. The official baseline now works cleanly as a level 3 Armorer without borrowing features or numbers from later levels.
