Magecrafter
I thought he didn’t know about medicine. If so then how did he go from inept to master in 5 days, enough so to discover potentially one of the most dangerous poisons is a world like this, one effective against any mage and more effective with more powerful mages by the looks of it! And I get he’s a genius but there are limits, and learning an entire profession in 5 days far exceeds them. And to his point, if one could discover this poison so easily that a novice could prefect it in 5 days then it is absurd that nobody had discovered it before, expecially given his explanation of how he discovered likely meaning that the creators of the remedy where aware of its effects ( using a poison to combat another poison (one would then know that there using a poison no?))
