re: Official Skyrim Ultrathread.

You equip spells to L or R hand just like a weapon, and can use both spells and weapons in combat. For some spells, there are special features if you use both hands to cast the same spell at the same time. The initial destruction spells are kinda like flamethrowers. Later on, you can learn fireball type spells.

You learn spells from reading books that you buy or find in dungeons. Unlike previous games, you cannot make custom spells.
