For starters, characters will possess too little orenda to 'do' anything spur of the moment. It is simply impossible in this setting to brute force magic. It's all ritual, to the point where it's considered just another branch of science in universe (and likewise best left to teams of professionals) But that doesn't mean you won't have magic. It just means it will be less something you 'do' and more something you 'own'

A player could as an example own a length of Tsukumographed rope. Being alive it could slither around, tie or untie itself at will or prove useful in any number of ways, able to follow simple commands (As long as the animal it was made from understood them.) I'll pretty much allow for most things to be Tsuked.

Another type of magic I'm leaning towards is construction being more or less guiding the environment to arrange itself in a particular fashion. So buildings are mostly natural formations made more cozy by the addition of human comforts. As this is again, very comparable to the time and effort that goes into putting structures up in real life that's not much use to a player.

I'm still fleshing out a few ideas, but I may allow for a more reactive form of magic that relies on players injecting themselves with a substance derived from extracted orenda before each and every 'spell', but the mortality rate of that will be so high that they only get a set number of uses for the entire roleplay.
