We might almost say that wizards in D&D with their necessity to prepare "spells" to have ingredients (material components, which are not simply a focus, but real components related to the effect, like sulfur for fireballs) should be more correctly named "alchemists", therefore leaving the sorcerers (and later the psions) the only ones really able to shape reality using only their sheer willpower.
