Since the identified problems/ambiguities of Magic in Character Creation
and Character Progression are intertwined, I think itīs a good idea to bring them all together. Hereīs what I extrapolated from the discussions in the forum
so far, with my personal, subjective take on the matter in parentheses.
- Do Phyiscal Adepts get additional Power Points when increasing their Magic Attribute with Special Attribute Points? (Personal take: Yes, they should. It worked well in 5th Edition, and while 4th Edition didnīt have a Priority System, there is an important consistency: Adept Power Points = Magic Attribute. Itīs easy to remember, easy to backtrack and doesnīt turn Special Attribute points into a mechanical trap for Adepts. In longer campaigns, there will often be moments where (new) players or GMs want to make adjustments to a character or just want to "check up" if everything is alright about a char. If increasing Magic through Special Attribute Points doesnīt grant Power Points while Karma does, youīll always have to remember that there might by a couple of "dead" Points in your Magic Attribute that donīt give you additional powers because you (foolishly) decided to use your Special Attribute Points on your Magic Attribute.)
- See above, but for MysAds? (Personal take: For consistency, do it just the same as Physical Adepts, + the additional Karma cost for "unlocking" the Power Point. I do think that 5 Karma per Power point is a bit low, though. Personally, I wouldnīt even mind if the rules from 4th Edition come back that forced Mystical Adepts to "split" their Magic Attribute between Adept stuff and Magician stuff. Since there are no flexible spell ratings anymore, this would be a lot more viable in 6th Edition than it was in 4th Edition.)
- Do Magicians get additional spells when raising their Magic Attribute with Special Attribute points? (Personal take: Indifferent. If I understand it right, the current RAW is basically like 5th Edition in this regard, just written less obvious.)
- Can Magicians buy additional spells with Karma during Character generation? (Personal take: Yes, they should.)
- Burning out, part 1: Do Adepts and Mystical Adepts lose Power Points when lowering their Magic Attribute when burning out?
(Personal take: Holy shit, yes! Is this even in question?!) - Burning out, part 2: Does it reduce your maximum Magic Attribute? (Personal take: Yes, it should. Else, burning out is just a temporary dip in your Magical Potential that can easily be bought back with karma).
- Wait a minute, is there even such a thing as a maximum Magic Attribute? ( Erm. Yeah, I think I saw it popping up somewhere, donīt know if thatīs really (not) in the RAW or if its just an oversight. The way I know it from 4th and 5th Edition, awakened characters can theoretically raise their Magic indefinetely as long as they keep on Initiating. Personal take: There definetely should be a limit in Chargen, but I highly doubt that this is missing, given the lack of another "Booo Magicrun" outcry about this
Having no limit past Chargen basically means that the need for Initiation has been removed, making the whole thing it a bit cheaper. Donīt really like it, but I also donīt think itīs a gamebreaker, given the progressive Karma Cost for raising Magic itself) - Burning out, part 3: Assuming I start with Magic 4, drop to Magic 1 because of Augmentations, and want to buy Magic back to 2: Do I pay 25 Karma or 10 Karma? (Personal take: RAW itīs probably 10 Karma, just like in 5th Edition. TBH, Iīd rather have it like 4th Edition, where advancement costs were based on the Magic Attribute you would have if you hadnīt lost Essence. This burnout-buyback-discount is one of the reasons why Burnout Adepts and Mysads were so popular with powergamers in 5th Edition.)
- Burning out, part 4: If I burn out down to Zero Magic, can I buy back my Magic with Karma? (Personal take: No. Or more precisely: Not for measly 5 Karma, not without GMs permission and not without jumping through some RP hoops - thinking about Glory in Shadowrun: Dragonfall here. Itīs always been canon that a total burnot means a total disconnect from your magical abilities thatīs usually permanent.)
Note: Iīm not arguing which kind of interpretation is
supported by the RAW, because
a. I know only some controversial snippets of the RAW and not the whole picture.
b. frankly, I donīt care. This is a thread about Errata, so letīs talk about how things
should work and not how the current RAW can or can not be interpreted

Also, if there is ground for discussion on how the RAW works, that alone is a reason for errata.
