Kits that have been ruled impermissible
NWP/WP RulesCharacters cannot trade NWPs for WPs. However, due to the lack of a common language and the general bilingual nature of most people in the Atva-Arunia, characters made in the setting receive a number of NWPs = to their bonus NWPs for intelligence JUST to spend on languages. More can be spent from the all-purpose slots. Only mages start knowing how to read, and that only their Language of Power.
No character, warrior or otherwise, can shift NWP slots into WP slots.
Two-Weapon Fighting - available as a prof (as per C&T) but it costs 3 slots.
Shield Mastery - only available to be learned in game, mostly taught by very old dwarves.
Mastery and Grandmastery - only available to be learned from certain dwarves and elves of extreme age and skill.
Time and CombatWe use the 15 second C&T combat round. This means we multiply the length of all spells by 4 (1 round now equals 4 C&T combat rounds when the fighting breaks out) during combat.
As I think of more, I'll add more. These will eventually be compiled into a rules supplement for FG&G.
