We need a new weapon type that is melee magicka based. We already have melee stamina and melee ranged, but only ranged magicka, so now we also need a melee magicka weapon.
Why not fists? Your fists can wear special magicka loaded knuckles of some sort and they are channeled through your willpower.
Example of some skills for this weapon set.
Falling Meteor: Punch an enemy into the air, increasing the weight of your enemy by 1000000, when falling down into the ground it will create an earthquake that stuns and damages nearby enemies.
Impact Punch: Punch to deal x amount of damage. Enemies in a cone behind the enemy will take 150% of the damage. Enemies are more vulnerable to your punches by 20% for 3 seconds.

Heart Grip: Punch a hole though your enemy's chest and crush his heart with your palm. Can only be used on enemies under 25% HP. Deals x instant damage and x damage over 5 seconds.
