the trailer showed magic with one hand and magic with two hands and magic from a staff. so far they still havent decided on whether or not there will be spell combos but if that is the case would that mean that casting a fire spell with both hands gives double the damage or maybe you can only cast the more powerful spells with two hands which is how i hope it is. as for staffs it would be nice if they gave a bonus to magic while you have one equipped this making a spellcasting mage with a staff an actually viable choice. is there any info out there that confirms or denies any of this or any additional information. im dying to know how the new mechanics work. :sadvaultboy:

If you equip two of the same spell, you cast one powerful. I think.

That is what I saw in the trailer

Yeah they explain it all in the GI articles.
