Ok, part two of my 'basic' questions...
We played the shilling adventure this evening and one player ran the Grey Wizard. The same question came up with channelling and casting spells that came up when I read combat.
Are both 'unopposed'? Nothing I found in the spellcasting rules stated as such. Magic Darts, for example, is not a melee attack or ranged attack (which receive a standard 1 challenge die), it does have its own difficulty (as do other actions) and we couldn't decide. And, is it an easy action, simple, etc if it should receive a challenge die? Without the challenge die a caster could channel power and cast spells like magic darts (which only adds a challenge die when engaged) all day without incurring a miscast. I'm sure I need to dig further, but anyone know where to find that its confirmed channel and spells receive a challenge die if a roll's required.
