Alchemical Physicians of Uldah indeed! Posh!!
That article was all but invalidated by the Elezen Entrepreneurial Enterprise back during the first Heavensturn of the Seventh Umbral Era! During the evil reign of the first elevation of Titan's powers, we could plainly observe all races being resurrected en masse, and not once did they turn on their fellow adventurers seething for flesh!
...they did seem to continue their propensity for chewing on rocks though...
On that note!: What we have determined is that (while not exactly brain rot) these multiple resurrections do actually accumulate over time into a detrimental personal effect that causes Debilitating Ulcers Manifested in one's Brain (EEE thought it would be easier to abbreviate this into D.U.M.B.).
There is no known cure yet....
