texture trinket companions

want to texture new trinket fairy companions , but need actually earn combat mastery to get companions ? no easy cheats ?
can use cjb to boost levels to 10 , but will get no further gain from there unless miss something . need actually play in test file to unlock things . oh no .

oh good ! did find answer to this from reddit thread ... which will now summarise in case that disappear .

with save file of choice open , paste into SMAPI console :

debug setstat MasteryExp 100000 

then warp ( or just ... walk ) to mastery cave and claim what need .
in this case just need combat mastery to test companion trinket textures . :P
