Play a botanist wizard and flavor all your spells as plant magic. Longstrider? Vines wrap around your legs like an exoskeleton, making you faster. Shield? A flower bud on your person blooms suddenly, deflecting a blow. Lightning Bolt? Generated by static in spontaneous cotton fluff that makes you look like a death-dispensing sheep. Illusions? Caused by floating pollen, scattering light to create something unreal. Need some undead minions? Check out the Myconids and their Spore Servants, or maybe the Yellow Musk Creeper from 3.5
