I think there could be a chance for something of the sort to Extract and Remedy for the Alchemist class. In the nature of Alchemist they could try and imitate life essence. A very Delicate and costly brewing process with a chance to fail. (Lowers based on Alchemy level? Starts off on a high chance to fail, Say 80-90% failure, and lower by 1% per 10 levels so as a master alchemist(around 1000-1500) they have a near perfect success rate.)
If the brewing succeeds they get 1 Imitated life essence, they then can cast a version of Remedy that has set chances to fail(also lowers with alchemy level- if possable). If it succeeds it works like regular Remedy. If it fails however, there could be diffrent effects...
: Nothing happens
: Recipient receives a temporary negative effect (poision, wither, hunger, ect.)
: Recive a higher teir Death state/Doom finger?
