And the difference between a Fighter-Wizard and Eldritch Knight is ... ?
Lots and lots and lots of more spell power, a lot more spells one can learn, and less hitpoints and attacks.
An EK 6 / Wiz 6 for example has spellcaster level 8 and gets level 4 spells.
An EK 12 has caster level 4 and gets level 2 spells AND only a few of them.
