a couple of questions, help with some questions raised in game Options

[scarius]

hey guys,

i was just wondering if you could help me out with a few things, as i stated in a different thread i am currently in a game back in my home town, my books arent with me and the guy GMing for us has had a few problem with rules lawyering in the past and as such dosent let anyone have a look at his books (i kind of understand as i was presant for one of these occurences, after the better part of a hour me and the 2 girls that we role play with said that our character go out of coffee, we then went to the pub and go throughly blind, after a good 4-5 hour drinking session we got a sms saying that we could come back and continue the game) as i live a good two states away from my home town and my mate has the books i only had to bring down a character. i helped one of the girls and one of the guy make there characters on the first night and now they have asked me a few questions which i cant answer because i dont know if its right or wrong, and they dont want to ask the GM as they dont know if they want to go this way with their character yet... anyway

we are using S4A, augmentation, runners companion, street magic, unwired, running wild, arsenal

1 is there some sort of track/locate spell that a magic user can use to find people from their auras/hair/skin/personal gear? or is this more of an assenssing (spelling?) thing?
2 is there any bio/cyber ware that incresses your intuition?
3 how can a troll get his body to 15 if you can only get 4(3?) levels of bone density?
4 what drones would you recomend for a rigger? eg: infiltration/exploding/assault/back up/ect ect


i think thats about it for now,

thanks in advance... i hope
