Suppressive fire is base damage. That Force 7 spirit needs to be buffed with a total of 4 armor to be immune - which is highly likely with a decent summoner.
Incorrect. It's logical to assume that regular Armor does not stack with Hardened Armor for the purpose of nullifying damage completely. A 10P/-7 attack versus a Force 7 spirit with 4 Armor from the Armor spell will still deal damage: its Hardened Armor is reduced to 7, giving a Force 7 Spirit of Man 8+7+4 dice (at which point the Armor kicks in to boost its total Armor to 11, making it 10S) and (7/2, rounded up = 4) free hits: that's 6S versus 19 dice: on average that's only 0.65S damage, but the spirit is
not immune to it..
Against a Force 7 spirit, the RPK HMG is a better choice for Suppressive Fire: 12P/-8 means the spirit has Hardened Armor 6, Armor 4 and Body 8, which means it's 12P versus 18 dice and 3 auto-hits, for an average of 3.06P damage.
Of course, another question is whether (Weapon Skill)+Agility [Accuracy] is enough to hit, since the spirit either uses the summoner's Edge attribute for its dice pool, or its own Edge (Force/2): in the second case, that's 13 dodge dice not counting any buffs it may have, and since it has a threshold to reach, it effectively wins ties.
And hey, if we're going to use ambushes, here's one: while the spirit slaughters two guard grunts the summoner doesn't realize aren't the street sams he wanted dead because he's several miles away, one of the real street sams figures out its exact location based on where its actual attack comes from (in which case, even using Trid Phantasm to create a bunch of shadow clones won't help). Then, the second street sam fires an Anti-vehicle missile (18F: have your face obtain it for you) at within 1m of that location (threshold 3 to hit): 24P/-4 means Hardened Armor 10 remains, effectively giving 19P versus 8+4+10 dice, for an average of 11.67P damage (6.78P if the summoner uses Edge for Second Chance on the damage soak).
Another ambush: between the cameras and radar sensors, at least one picks up the spirit's location while the spirit slaughters the guard grunts, allowing two snipers to (at the very least) Blind Fire from 500m away even if the illusion itself fools them. Since the spirit is unaware of the attack, it gets no defense roll, which means the Blind Fire and other modifiers don't really harm the snipers (since it's a Success Test). Using a Ranger Arms SM-5 with APDS, and with a dice pool of 6+6+2+2 - 6 - 3 (6 skill, 6 attribute, specialization, smartgun + 'ware smartlink, Blind Fire, environmental modifier of -3) = 7, and spending a point of Edge with Edge 4, the snipers score 4.28 hits on average. Assuming 4, they each deal 18P/-9, reducing the spirit's Hardened Armor to 5: 3 free hits means 15P versus 8+5+4 soak dice gives an average of 9.33P damage (5.56P if the summoner uses Edge on Second Chance for both soak dice). Two snipers means 18.66P damage on average (or 11.12P), and if the snipers only attack after the grunts are dead, it counts as a seperate combat challenge to attack them.
Actually, it has used 1 service.
Prove it. What was it told to do, go into this room and materialize? Scout the room? Doesn't involve combat. Attack people it doesn't know are there?
If we are talking about just killing a couple street sams: "go kill those men" is 1 service for a bound spirit. The bound spirit must do its utmost to fulfill the command.
"Go kill those men that I can't see because I'm 5 miles away"? No. The best you can hope at with a single service under those circumstances is "Go to that room, and if there are people there, kill them" - and that uses up a service even if there's nobody there, and requires you to have done some scouting or sleuthing beforehand, or use a different service to tell the spirit to scout the room, after which it will return to you - you'll then have to send it back with a "kill them" command for another service.
5. Note that spirits are subject to drain and since they have only one condition monitor, they are basically burning their life force to cast the spell.
Not exactly: the rulebook says "If all of the boxes on a spirit’s Condition Monitor (
either of them) are filled, the spirit is painfully disrupted and is forced back to its home metaplane", which means spirits have both a Stun and a Physical Monitor.
