Keep her high strength, and take at least three levels of fighter. As an Eldrich Knight, she can throw her bound weapon and it returns to her hand. Take Tavern Brawler as your Feat and you will get +8 damage when you throw any weapon (assuming you have 18 Str with the +1 from the Feat). Multiclass as a Cleric and use your bonus action for Healing Word when necessary. This should really be enough in the early game. Work to get both classes up to level 5 (the bonus attack is really nice) and max out at Cleric level 7.

"He that can smile at death, as we know him. Who can flourish in the midst of diseases that kill off whole peoples. Oh! If such a one was to come from God, and not the Devil, what a force for good might he not be in this old world of ours."
