In the skill description for all schools of magic, there is a perk where your spells in that school of magic will be stronger when dual cast. I finally decided to take up this perk for alteration school of magic and then tried dual casting my adept lvl shield spell. I cast with just one had first and checked the armor stats. Then I dual cast the same spell and again checked the armor stats. They were both identical, providing me with the same armor bonus regardless if I dual cast the spell or not. I even tried it naked, same results. No difference in the power of the armor bonus. Thankfully I saved just before taking up this perk and just went back to saved point after. Phew, 1 precious perk point saved.
Can anyone confirm this is the same for them. If so, I am wondering if my precious perks were wasted in my other schools of magic, ie destruction and conjuration and if this perk actually works as described?
Thanks.
Cheers,
