If I summon a Spirit of Man force 6, it can have two optional powers. Those two optional powers could be two spells that I know since they are capable of spellcasting. If I choose Improved Reflexes and Improved Willpower I believe I can use two tasks to have the spirit cast and sustain both on me until they are dismissed.
A few questions:
1.) Is my scenario accurate?
2.) Does the spirit have to be on the physical plane to maintain the spells (for that matter, does a magician have to be on the physical plane to maintain a spell or can they maintain spell astrally?)
3.) Somewhat tangential, do spells with a range of touch that are sustained require the target to be molested for the entire duration of the maintaining or is it just the initial casting?
