Another thread has me wondering what kind of action Aid Sorcery requires from the bound Spirit.

I tend to go with the first option, since that allows multiple contributions to Counterspelling in a turn (although at the cost of many services) and also avoids any delaying of actions.

The spirit uses a service to help the magician, the service involves aiding a complex action, so it too should be a complex action.

So far a pretty even split between the first and last options. Is there any 1-3E precedent on this?
