Dragyri air caste and healing

[Fe'ral]

Hi, long time player and lurker.
I have forsaken, ice caste, and brood who in their own way can return HP to members. However in building an Air Caste list I noticed that there is no foci with any healing affect. Am I missing something or if not then maybe there should be a foci added like chill the blood for the Air Caste?
Thanks
