Works for any non-combat action, but for lulz
Vulcan liege lord RCC or similar. Rating 5 anyway.
I-Doll, Realistic Features 4, Stacking Mortimers and some Black Panther for a +3.
Every Social Skill Autosoft at 5.
Swarm the silly thing to 14 Kanmushi drones, all running Stealth 5 (or Palming maybe?)
So, Pilot 5, Autosoft 5, 3 social mods, so a not terrible 13 8 Dice, +14 from Swarm, 27 22 Dice on Social tests, with a limit of around 20. Swarm all has 24 dice of Stealth/Palming so the horde of Spiders is fairly well concealed.
Cripes build a RCC with enough Sleaze and whatnot... 24 dice Stealth, no astral signature, the Kanmushi aren't triggering any Alarms, you should be able to get 18ish dice to resist Matrix Perception if you try hard. Get double digit Noise Reduction and as many Non-combat Autosofts as you can afford. As long as you never have to roll initiative you're going to stomp any sane opposed or threshold check. 24 Dice on Social skills, Technical Skills, Sneaking, Perception, Hacking.... RAW is anything you can get an Autosoft will basically have a dice pool of 24+ with a Device Rating 5 RCC.
I mean, sure, any player pulling such a stunt should be smacked with a book. But c'mon. Jeebus, Swarm is broken. Sorry I'm late to the Swarm Party, but I never really read it, I had always assumed that it was something sane. Not "For 14,000 Nuyen your Drones can take a +14 Dice, +14 Limit, on any skill you can get on an Autosoft." I presume at some point in time some kind of limit will be added? Treat it like a teamwork test and limit the bonus dice to the Autosoft level or something.
Okay, rant over, I was fiddling with a Telepresence Rigger concept this morning and thought "Why not be the Face too?" and actually read Swarm specifically looking for the sane limit I had presumed was in there. Now I get it. Jack_Spade is correct in that the answer is always Drone Swarms. Had no idea.
Edit: Minor Sanity, Drone Autosofts aren't for every Skill in the Game, so shucks only 18 Dice plus whatever gear mods you can find for any Default-able Skill in the game. Not that any GM would let that happen, but that's the RAW.
