The problem with those however is that the thrush only manages a 30ft radius, and "healtful rest" only targets 6 things with ECL6

Dragon Shaman route is quicker than the Touch of healing route to the same end as it requries no actions and you can effect multiple targets at once.

Healing very large numbers of people beyond that is going to be very difficult and binder may well be your best choice for doing it in a manner that doesnt consume all your daily/financial resources.
