Both talking about downtime, and making money. Now, here's the rundown, and the problem....with a plea for help and ideas. The rundown, is, in the campaign I'm in, our GM is looking at a payout of around 10k per run, with one run per gametime month. He figured this was about average. If its not (which I have no idea seeing as its been forever since I've played, let alone 4E, let alone my last GM always HATED letting his characters buy anything other than at chargen....) I'd love to know what "average" usually is. We're a decently skilled group consisting of mage, two adepts, and a techno. Now, the GM encourages us to come up with what we do during our "downtime." I myself have Chemistry, so can have all kinds of fun making different chemicals (if you have suggestions on which ones would be best, I'd love to hear that) and the Mage can do enchanting and all that entails.....and the Techno has the whole Matrix at his fingertips. The conundrum comes down to the other Adept.
They went with a gunslinger adept, and so felt that Armorer, with spec in firearms, was appropriate. I wholeheartedly agree. The question comes down to the dice pool, since we have to buy our successes, with the GM not being there to verify rolls. With a Logic of 5, and Armorer of 5, this gives her 10 dice. She's opted for a shop, instead of facility, since she didn't have the starting nuyen for one anyways. Eventually getting a large desktop forge to "count" as a facility. However, at the moment, she's only getting a DP of 12, meaning 3 successes. Is there ANY other ways of boosting her dice pool for the actual tests? I know of improved ability for adepts, and that'll be taken once the skill gets to 6....but we're still only really talking about stats+skill+spec. Is there something I'm missing? What is a good setup for actually modding in order to maximise returns? Thanks for all the advice you can give us!
