Stoneskin II

If you have her in Sic mode and you time it right she will use that HoT whenver you use Succor so it can be pretty effective

I guess you can do that and make a makeshift Medica 2, personally I like everything being on manual so I can do Rouse + Fey Illumination + Whispering Dawn in that order at will and also throw in Covenant.

If you count SS and SSII as different actions, why do you not count "whispering dawn" and "embrace (eos)" as separate actions both available to an SCH?

You have to be aware it's handled that way because of how SCH was tacked on to Arcanist, so they had to move a lot of those utility abilities onto their fairies or else they'd fall short on the healing side, since Arcanist only has 2 healing abilities and one is pet only, I guess 3 if you consider the very minor self healing from Energy Drain.
