I just had a thought about the combat system.

What it sounds like to me, is that to use a spell you need to equip it, much like in Morrowind. However, you have two hands in which to equip items. You can go sword + shield, Sword + sword, Sword +spell, Spell+spell, etc. It was interesting to note that it said by equipping two spells, you can create a new spell that is a combination of both.

But what if I was to mix two completely different types of spells? Say a fireball and a heal spell? Will such a thing even be possible, or will you only be able to combo similar types; like heal + shield or fire + ice but not fire + heal?

Well, it won't be so much 'mixing' spells, as it will be right-click for fire spell, left-click for heal spell. You aren't casting them as a single spell.

Apparently Todd stated this is not possible to combine spells, the Spanish Mag? also states this. sorry.

only the devs know for sure. it has been officially commented on but whethor or not what's been said is mistranslation or misinterpritation has and is being argued on these forums.
