That's actually a really good question and I need to post this damn write-up I have of how magic specifically interacts with mediums. Here's how it works though. And I left a TL;DR at the bottom just in case people want to skip straight to the summary lol. 

Magic channeled through a human body is 100% guaranteed to cause the disease which will mean organ shutdown until death. As such, humanity learned to harness magical energy through mediums, or objects as it were. With a medium, one is able to gather magical energies without actually channeling said energy through their body, thus avoiding the disease. Unfortunately, it's not that cut and dry though. The power of magic is generally governed by the strength of the medium one is using. I gave someone else the example of having a character using a key to maybe magically unlock doors and using it as a medium for a weapon construct--all that would be perfectly within reason considering the source is a key. However, if one attempted to conjure up a lighting storm with a simple key as a medium, the spell would fail and the key would be destroyed because it wasn't a strong enough medium to handle the necessary energies. This is basically the logic of magic in the world of Pratus. 

To answer your question specifically, one could indeed enchant armor sets or weapons and gear. The gear or armor itself could serve as the medium and that would be perfectly fine. Where it gets murky is constant activation. If the spells one wishes to use on the gear are in constant, passive use then the wearer of said gear will likely develop the disease after some time due to being in constant contact with the medium and having the energy seep into their body. Spells are meant to be a one time use and then one must conjure again, but enchanted items carry the greater threat of poisoning their users or wearers and attracting the supernatural due their passive, consistent use. 

[b]TL;DR[/b]
Yes, enchanted weapons, armor, and gear are certainly a thing in this world. However, they carry the threat of slow poisoning if the spells they conjure are in constant, passive use. The wearer or user would slowly develop the disease and then suffer the same fate as one who tried to channel the energy through their body. 

EDIT - Added the write-up under the general information section called "Magic: Part 2". Hope this answers your question though.
