I am fairly new to shadowrun, so bear with me.
I am currently playing an augmented physical adept, which is my first shot at an awakened character. I have 2 ESS worrh of ware, a MAG score of 4*, and I am about to have enough karma for my very first initiation, which I only want for the ability to invest more in MAG for another PP. None of the adept metamagics look any kind of useful, except for perhaps adept centering and infusion, but I keep seeing extra PP purchased in place of metamagic in builds online. However, thee rule that lets one do this escapes me. Where kan I find it? I sure hope that it is not just a common houserule or some optional rule, as that would never fly at the table I play. Also, does adept metamagic really suck? I suspect that the reason that none of them look useful to me is that I don't know the rules well enough.
*Soft capped at chargen, and later increased with karma.
