Leirn is a young Biochemist with a fetish-- err, passion for plants and... well, plants. He is proficient with most chemicals and transmutations, and can make a mean Molotov Cocktail.
Leirn is very mischievous, as his favorite hobby (asides from hugging plants) is pranking people around him. No one is safe when he throws an tantrum, as his various concoctions are either acidic, explosvie, and generally volatile in nature. Not to mention he can create plants to do his bidding (one of the perks of studying them).
Various vials, a traveler's pack, rudimentary weapons, a chemist's set, and many, many catalysts.
Leirn was the son of a very famous biologist, who bequeathed all his knowledge and research to him upon his death. Leirn took up that mantle and carried it a step further, delving into the (somewhat) forbidden art of Alchemy (a science of transmuting properties of matter). Leirn thinks that he had practically invented the science of Biochemistry (since he has yet to run into another practitioner).
