Spycraft already has Rep/Net Worth, so porting over shouldn't be hard. And Profession checks are the preferred method of increasing Rep gained after each mission. If you're wondering about starting Rep, the Rules As Written say it's 2 no matter the level. If you'd prefer something to work with, FC's 10/level works pretty well.
I typed that one a little quick. Didn't finish the complete thought. I blame work. Agent is spot on. Let me a little more thorough.
"Lost" magic w/ Cash n' Carry. Net worth disappears and Reputation remains. Let's say my players weasel out and scheme $10,000,000 from a bank, a country, what have you. Would it be 'simple enough' to just break the Rep cost down to cash by using the Net Worth equivalent? 2 Rep = $100,000 cold hard cash? At which point... a level 5 spell is...
(5 Rep x 5 x $50,000) 1.25 million in cash or 25 Rep?
FC Wizard Level 3 completes 3 Caliber III "Missions". Walk away with 39 Reputation.
SC Hacker level 3 completes 3 Caliber III "Missions". Walks away with 30 reputation. 39 only if he makes 3 successful DC21 Profession / Accomplishment Checks.
My concern is.. I'm trying to make magic a plot lynch pin and make it very 'special' to the party. "Lost" effect and what not. However.. I'm just hesitant to how the loss of 9 Rep would factor in if they choose not to sink in the skill points to keep up with the FC math. I want to have a magic class available, while difficult, I don't want it to be the only thing they spend time / money on. I want to leave the char with some Rep to play with.
I may just modify the multiplier for Lost to give the players a little more reasonable to have a caster in the party. Mainly because that sort of cash flow would mean if the player skims on the magic I'm assuming they're going to be taken, they'll be power equipment gaming (or throwing around money like snowballs).
