So my group is getting ready to kick SR5M into gear, and I've been designated character updater for a fellow player who is still trying to learn everything. Knowing he's going to want to be looking at purchasing and upgrading gear (he's a cybered combat decker build), I realize that outside of the bare basics (ammo), I never bought anything in Season 4. I looked through the SR5 rulebook, but I'm having difficulty understanding the buying rules in regards to posts I've seen here. I know that you have to buy hits (four dice per hit) to buy an item, and that contacts can buy you gear if you're not a face type (and thus do not have the necessary social graces). What I seem to be missing is some of the formulas used to determine how it is done, and how long it takes.
For example, I've seen it posted on the forums that a contact buying gear uses [Connection x 2] + Loyalty as the formula to figure out how many hits can be purchased. However the book says (on page 418, Contacts and Availability) that contacts use their Negotiation and Charisma with their Connection Rating serving as a bonus to their Social Limit. Am I missing a rule that changes this somewhere? I checked both the SR5 Errata and SR5M documents, but saw nothing changing what the books says.
If it is indeed [Connection x 2] + Loyalty, help me break down the process with the following scenarios, please:
Scenario 1: Sammy the Street Sam has a contact, Fred the Fixer, with a 6/1 rating. Loading up on all kinds of cyber/bio goodies, he forgets to purchase eye upgrades and now needs to purchase glasses [Rating 4, no availability code] with vision enhancements [Vision Enhancement [3], Smartlink [1], availability is now 10R] for a 2400Y total cost.
According to the formula above, Fred would have [[Cx2] + L] dice, or 13 dice to buy hits, giving him 3 hits, correct?
The glasses, having an availability code thanks to the enhancements, would have 10 dice to buy hits, for 2 hits, correct?
Looking at the Delivery Times Table on P. 418, 2400Y takes two days. How long will it actually take Sam to get his glasses, assuming he doesn't throw extra money at Fred?
Scenario 2: Sam and Fred are at it again! This time, Fred's fake SIN got burned and he needs a new one that's of a higher rating. He contacts Fred, and requests the best fake SIN that Fred can get [R6, 18F, 15,000Y]. Assuming Sam is a tightwad, and doesn't wish to throw more money at Fred, can he even get the new SIN - Fred has 6/1 - or 3 hits, versus 18F or 4 hits? With a delivery time interval of 1 week, if he can get the glasses, how long would it take?
