I found the Mutagenic Potion on Jin'tiz the Cataloguer's table. In order to create the Transmogrification Elixir, I must find Doom Lord Septimus, kill him, take one of his scales and grind it into the potion. After that, I'm supposed to drink it. Hopefully I don't get transformed into some horrid beast.
