OK - I'm not so smart

To attune your doll to a target, either click on them, or hit ctrl while you're facing them. Then when you use your attacks or heals, it will only attack or heal whoever you're attuned to. When you level up, you can put skill points into the top thing to be able to attune to more than one enemy/friend. However, if you are attuned to more than one enemy, the damage will be split between them (same for healing friends).
