I've created a character stats' topic for your magus. Put his final stats there at the time of his Gauntlet.
https://forum.atlas-games.com/t/belisarius-of-house-jerbiton-stats/172014
- First post should always be his current stats
- Second post should be his advancement log
- Third post should be for custome spells he has
- Additional posts can contain past versions of his stats (for example if you want to keep a snapshot of him at Gauntlet and another one at the start of play), description of his lab, enchantments of crafts, additional details, etc.
Once that is done, then you can start on the first year (only) of pre-play advancement here (not with the stats). Let us review that before you keep going. You can start with just a single season, or do the whole year if you prefer. Then we'll comment on it and give you the go ahead for additional years. That gives us a chance to check for assumptions before there are too many layers built on top of something that might need to be adjusted.
