To complement a brief update from Derek Paxton about the focus they're putting on spellcasting in Elemental's Fallen Enchantress expansion pack, Stardock has released a downloadable PDF that details the add-on's magic mechanics, as well as the base, air, death, earth, fire, life, water, faction, researched, and quest spells we'll be flinging around with reckless abandon.
This alone has convinced me to reinstall my copy of Elemental as soon as the expansion launches.
