The basic framework for NorseQuest II's system is something along these lines.
Orthstirr: Instead of counting every individual mote of orthstirr, we now go by general 'level' of orthstirr. So, Halla right now would have, like, 20 levels of orthstirr to spend in combat/other things (undecided if that is how much she would actually have). While planning for a round of combat, you'd decide how many orthstirr levels to spend on that round with higher spendature meaning the MC has more power to work with and bonuses to their moves.
Tricks in Combat: Instead of deciding exactly how many times you're going to throw out an attack or what have you, you instead decide what tricks the MC will have available to them to be used as needed. Hugr Capacity would no longer be an over-all limit, but instead being how many tricks you can have readied for action in a single round. It would literally be what the MC thinks to use in that moment.
Combat Stats: Instead of having a bunch of different combat stats, you have a single 'primary combat' stat that includes all the cutting, slashing, stabbing, and all that sort of thing in it. On top of that, you've got your martial styles which have their own bonuses to things. Also, individual capacity for stats and stuff is being gotten rid of
Now, this is all very WiP and is not the entirety of the rework, just what I've landed properly on so far.
