Sorcerer (Dungeons & Dragons)

Sorcerers are really just singleminded versions of their Wizard brothers, able to cast spells spontaneously (e.g. without preparation in the morning).

Players of Sorcerers (not to be mistaken with Saucerers) often enjoy the dragon blood fluff, and use it in some vague attempt of roleplaying, but we all know that deep down inside they're just playing a sorcerer because they want to throw more fireballs per day than the wizard.
