1. Machine Cultist: This artificer brings to life all your fears regarding artificial intelligence if played as themed. Very futuristic, very grim dark, 40k or Skynet from the Terminator. Artificer/Warlock hybrid.
2. Reanimator: Do you want to play the insane scientist archetype (see Frankenstein) bringing the creature/beast to life.
3. BUT!!!, that's not all! 2 pages with new Artificer infusions: The injector has the rule of cool down, but the advanced potion craft is sexier.

Quality artwork like all Grim Hollow - Ghostfire Gaming products. It's a yes from me.

Two horror-themed artificer subclasses:

• Machine Cultist: Basically a warlock artificer, who gains powers from a far-future machine of evil. Very flavorful, with interesting mechanics, largely centered around granting warlock features and an "Infernal Engine" vehicle. The catch is that this subclass feels very specialized, especially with the vehicle focus.
• Reanimator: An artificer with a golem ally, as well as lightning-themed powers. Again, very flavorful with interesting mechanics, and somewhat more broadly usable than the Machine Cultist.

The two subclasses are followed by a set of new artificer infusions, both for the new subclasses and (somewhat more randomly) for the core artificer and official artificer subclasses. I'm not sure about the balance on these, though they are, again, very flavorful. (I particularly like the Potion Injector Projector, a crossbow that fires syringes filled with potions at targets.)

The product overall has very high production values, to include great custom artwork (though it did miss a few typos). If you're looking for artificer options for a fantasy horror campaign, this product is highly recommended; this material is somewhat less useful for more general campaigns, if still very interesting.
