I don't want to sound harsh, but I think you're taking too sharp a reading of this rule.
You don't sound harsh to me at all. And I hope I'm not comming off that way either. I'm simply trying to make two points.
the first is that in adjudicaing the magical part of the game it is especially important to be vigilent in not allowing too broad an interpretation of the rules. The pit fall here is that being too lenient and lazy about applying the rules to one character achetype--the mage--is what causes imbalance in a rules set that is actually well ballanced. The "tertiary characters" (drones, agents, sprites) of Riggers, Hackers and even Technomancers have pretty well defigned limitations. This is not the case with spirits. Intuitively players and rules limit the utility of tech based helpers because we have some IRL experience with those limitations. On the other hand the tendency of players of spirits is to treat spirits as allies with free will, which they are not.
My second point is that there
are no rules for requesting an unbound spirit complete a TASK. A task would be a series of actions requred to achieve a goal. A strict reading of the rules for commanding unbound spirits
should indicate that you cannot make such a request or command at all. Period. However, most spirits are intellegent beings and 'should be treated like NPC's' so I personally do allow lattitude for generalized requests that are actuallly tasks such as "kill that guy". Strictly speaking though; a player cannot request a TASK from a spirit he can only request that the spirit provide one of four well defigned SERVICES.
Because I think my verbiage hasn't been understood in above posts."Kill that guy" =
Task and may require several
Services as the spirit will find the most effective way to complete the task and might chose both combat and the use of powers or several aplications of a power. A good example would be an air spirit casting several lightning bolts at an opponent.
"Attack that guy" = 1
Service as the spirit will then enter physical or astral combat.
"Engulf that guy" = 1
Service it requires the spirit to use a power.
Why I think that Materialization Costs One Service.QUOTE
pp. 186 sr4a "Spirits"
Spirits are creatures native to the astral plane and metaplanes. They
primarily exist as purely astral forms. Though such entities can sometimes
materialize and become tangible in the physical world, they dislike
doing so, and their true home remains in the astral realms.
Why I think that "Energy aura" usually doesn't cost the use of a power.Energy aura is an optional power that is a continuous radiation of the spirit there are no mechanics that indicate that the spirit is capable of turning it on or off. Also it generally applies only in the case of melee combat. In the case of the command "attack that guy" the spirit has no discresion to apply the effect or not. The command costs 1
Combat Service because the command was for combat. In the case of the command "light those drapes on fire" or "make me some ice cubes" We should assume that, unless the mage is an asshole, the spirit will make the most efficient use of
Services in accomplishing the
Task the spirit with Energy Aura would likely be successfull with a single application of it's aura while successive use of an elemtal attack might be required.
Note: the same application of common sence would apply to the Natural Weapon power.
Why I think that each use "Elemental Attack" costs a Service the same as any other Power with a Duration of "Instant".Mostly because it is a power the same as the Accident power or the Innate spell power. I have a hard time believing that any player would expect a GM to accept a comand like, "Use your accident power on that guy over and over till he dies." as a single service. A Spirit of Man might be able to cast Flame Thrower as an Inate Spell power but resists drain each time it uses the power. Obviously it's gona cost a service each time the spirit has to resist drain. Flame Thrower is almost exactly the same thing as the Fire Spirit's Elemental Attack. Just because a fire spirit doesn't have to resist drain doesn't mean he's going to go blasting everything for free.
Finaly:QUOTE
The use of combative powers or abilities by a spirit on behalf
of its summoner only counts as one service, regardless of the number
of foes involved.
Obviously this means that the use of powers that might concievably effect multiple targets such as Paralyzing Howel, Engulf, Concealment etc. cost only a single
Service per use no matter how many targets are effected. The command to "Use Paralyzing Howel" might concievably effect thousands of targets but is is a single use of a power and costs a single
Service. The reasoning that the quoted sentence means that successive use of an Elemental Attack power on multiple opponents costs a single
Service enables the command; "Go shoot a thousand orks with fire." as a single
Service. Such reasoning is ludicris or at least illogical and conflicts with the rules.
