Can you tell me about that? Cause I've never seen much creating artifacts in Exalted.
I'm not overly familiar with the mechanics, but the gist of it is that you have to build up resources to get the materials to create stuff, and then you have to invest the time into creating the objects. Given that we're an Infernal Coven, most of our stuff will be made with Chalcanth (demon Essence, basically - see the threadmark for how it's made in this quest), vitriol (an element unique to Malfeas, and vitriol corrupted magical materials.
Effectively we can get weapons, armor, and gear that provide effects related to what demons were used to craft it.
A few example artifacts from Infernals:
Chaos Targe (3 dots): Forged from a scale of Oramus's wings, this shield gives +3 to the wearer's DV against all attacks, and allows the user to apply their Parry DV against unblockable attacks.
Time-Strung Bow (4 dots): Made from Szoreny's tarnished silver wood and strung with a thread of Time, the user can spend one willpower to shoot an arrow into the future. At some point in the next five days (Storyteller decision) the arrow will attack the target, regardless of location, as an unexpected attack.
Key to the Infernal Gates (2 to 4 dots): Key allowing fast travel into Malfeas via any door in Creation. Does not allow fast travel out. (The Scarlet Bridge allows two way travel, though I'm not sure if the Creation endpoint stays where it is in Creation after summoning or if it goes back to Elsewhere - may need a unique attunement rule if the latter, given you have to touch an attuned artifact every 25 hours to keep it attuned)
Of course, I expect we'll come up with some original artifacts (especially given we have Charms to help create unique items) and many of the artifacts we make will end up being modern weapons and equipment fused with demon stuff.
