Railhammers have been forged in the deep pits of the Scorched Plains since the founding of the Covenant, making them durable tools in the construction of Hellhorned armor.
Railhammer, whenever Armor is applied to a unit, increases the amount applied by +4. This applies to Armor that a unit intrinsically has when played and Armor given to it by a Unit essence (The Last Divinity (DLC) only).
Railhammer provides a considerable amount of longevity to your units provided you frequently apply Armor to them, and the benefit only needs to apply once per unit for this Artifact to be almost on par with Scorched Steel (whose benefit is also increased by +4 if you have both of these Artifacts). Steelworker's power benefits from this Artifact, once per turn per unit on its floor, making it a particularly good pairing with it.
Railhammer is at its craziest when obtained in a run with the Stygian Guard, as units with Incant effects that provide Armor, such as any unit with an Runestone, Guard of the Unnamed, and especially Guardian Stone, become insanely strong with this Artifact, benefitting from it on each Incant, and in Guardian Stone's case, on each unit on its floor as well. (Note that if you have Capricious Reflection, Runestone can be found on any unit.) It can be quite strong for similar reasons with Echowright's Shellsmith path.
Railhammer's value depends on how much Armor-providing effects you have, but it doesn't take many for this to be a good Artifact.
