lol so, sorry if this has been said, I only read the first 9 pages *gasp* and the amount of off topic made my head spin 
lol.
lots of great idea's here but my tank is a mage, none of the magic I throw at him works because of sheilding. He always has 10+ dice in it as he uses assault rifles and sustained spells. Acid sounds good but the Armor spell is on top, would the acid get through? Can you call shot to negate armor when he has a 10 force armor spell, full suit form-fitted body armor, and a full suit a security armor (all of which cover head to toe)? Oh BTW he's always invisible and silenced (indirect illusions are only resisted if the observer has a reason to suspect something is there), with an elemental scouting for astral targets that can give him away.
I'm having a hard time hurting him with out slaughtering the others
A) With this many sustained spells, he has to have either a bunch of foci, or a bunch of spirits sustaining them. Either of those will draw attention (unless he's taking multiple -2 penalties for sustaining each spell? But I doubt it...)
B) Even the most minor ward (breached or not) will glow like crazy if this guy walks past it
C) FAB Bacteria will mess with his spells, as will motion sensors, pressure sensors, MAD scanners or many forms of other easily-accessible security detection
D) A F1 watcher spirit will see him, and these are rented out to even low level corps
E) Dual natured watchdogs (Barghests, Hell Hounds etc) will have fun with him
F) Spirit/Critter powers will work wonders on him. Most don't get any Counterspelling defense
G) It's hard work to get Security armour onto most runs. Give them a few where they can't sneak armour or assault rifles into the mission
H) You can't call a shot to negate armour, but you can do +4DV. That can hurt a person.
I) There's ALWAYS someone tougher. A single Astrally perceiving enemy (Ghoul? Perceiving Mage?) with any of the below will knock him on his ass, especially with a couple of net successes:
-- LMG on Tripod: Full Auto Narrow burst = 15P. Average you'll need 45 dice to soak that.
-- SMG with APDS and Full auto also = lots. 45+ dice to soak
-- TAZER of any calibre with a called shot will get you to 14DV and HALF-IMPACT armour.
-- Unarmed/Melee Combat with knockdown tests
J) Reflecting ward at a nice high force (Street Magic). Happy boy walks through, and if he's lucky, he doesn't fall unconscious. However all his seperate foci and suatained spells are fried.
K) It takes time and effort to layer sustained spells and armour like this. Surprise him at some stage
L) It takes 10 successes to get R10 armour, and a F10 spell to boot just to try it (unless rolling Edge every time). Are you enforcing drain on this guy at all? Also, this requires a F10 focus or F10 spirit to sustain (o.O) if you're letting the PC play with these power levels with no consequence, I'm begginning to think this issue may be your own damn fault!
M) Acid spell is resisted with Counterspelling and Half-impact armour. Yes it will get through eventually but unlikely to be fast enough with all the Counterspelling and armour dice we're talking about.
N) Invisible and silenced does NOT mean intangible. The PC still has physical form, so water, mist, air currents, puddles, adept powers (Mana sense I think it is? Or Sensing Metamagic) will pick the PC up no worries.
O)
The armor spell glows (Bright blue iirc). That should deal with the invisibility.
Glow definitely. Blue colour however is an old edition holdover
Either way, this should allow automatic rolls to resist the Invisibility indirect illusion
P) Indirect illusion only works on technology (Cameras, microphones etc) with 5+ successes on the spellcasting test (to beat the Object resistance). This requires 15 spellcasting dice (on average) or 20 dice to automatically buy the successes. I'd definately make him roll this, and the required drain, every damn time.
There, so that's what, 15 ways to screw with any munchkin-mage. Have fun
