Thanks for the H tip - should be useful in other situations too. I looked up the controls when I restarted playing this game, but somehow I missed that one.
The Spell Combination sounds great - with my current Spellpower, it would cause 45-50 damage per tick, which would be just great. But unfortunately, none of my mages have gone down the Electricity damage line, and I don't want to use a mod to reset points. Have you used a 3 mage plus tank party - I think that with lots of Lyrium Potions will make quick work of anything that is not a dragon. I hate dragons (okay, only faced two yet), especially the one that you meet while doing the Urn quest. Good think that fight is optional because I couldn't kill it even on Easy.
EDIt: Just realized that if I had used the Storm of the Century on Easy difficulty, even that dragon woould have died.
