This is supposed to be two to three paragraphs of general impressions. As I understand David's instructions there is supposed to be another file containing a full playtest report.
Ok, this is a first draft. I am sure it can be improved a lot so feel free to edit it.
The chapter presents a good balance between new rules and background information on House Bonisagus, providing flavour for characters and rules to enhance the game. Overall the chapter left a positive impression. Most of the rules fit the flavour of the house with the exception of folios. Some points could be improved, most of them are related to the treatment of the Trianoma lineage.
The chapter focuses mostly on the Bonisagus lineage of the house. Most of the history section concerns Bonisagus while the information about Trianoma is comparatively limited. We especially missed more information on her magic tradition. Song magic is mentioned once but there is no further information how it works or how it was integrated into magic theory. Some of the paragraphs dedicated to Trianoma discuss the Seekers, a group only very loosely associated with the house. Although the Seekers are interesting and are well suited to provide interesting stories we think the space could be used better for more details on the Trianoma linage itself.
The rules for original research are a great addition for Bonisagus characters and potentially useful for magi from other houses as well. When starting original research it was unclear in some cases what suitable projects would be. The different examples for original research take up a large amount of space without adding much to the game. The Arma Magica example would work just as well or even better with fewer folds.
These are the notes I put up earlier for reference.
