In one of the videos in the skills category under destruction it says, "The School of Destruction involves the harnessing the energies of fire, frost and shock/ This skill makes it easier to cast spells like Fireball, Ice Spike, and Lightning Bolt." Ignoring the incorrect grammar, what does it mean by, "Easier to cast"? Does this mean we are going back to a chance based spell system like in morrowind, or that it will cost less the higher in level you go?
