Odins Will

After years of training and forming a bond with your weapons you're now able to cast "weapon bond" from the Eldritch Knight subclass; This returns all thrown weapons back to your inventory but is only available for throwable weapons such as Shortsword, Dagger, Mace, Handaxe, Javelin, and Spear. 

You also gain a +2 on the attack damage from thrown weapons, and can cast Mage armour once per short rest so long as you're not wearing amor heavier than the light category.
