Most of your 'spells' are sword skills, so they wont cost magik. Lets call elemental juggernaut fire type, and lets say last stand is a natural ability. The remaining few wont cost much magik. Lets say Juggernaut is the largest at 6 magik, the 2 shout types would each cost 2, and smithing would cost 3, but as they are low level spells, would you rather learn new ones later, or have their power and cost progress as your level does?
