TFS 1.X+ TFS 1.2 Nostalrius exp formula

[Vantoria]

hello i have a question, im trying to change the exp formula from tfs 1.2 nostalrius edition well i want change it to like

((level * 50ULL) * (level * level * level) / 500ULL)+10ULL

but that one i cant use on tfs 1.2 because it is from old otserv it is basically the mastercores exp formula.
this is how i have it

return ((50ULL * lv * lv * lv) - (150ULL * lv * lv) + (500ULL * lv)) / 3ULL;

you probably need to reset the xp and levels on all your chars in db

im testing alway with new chars so i think no

EDIT:
did it like this

return ((50ULL * lv) * (lv * lv * lv) + (500ULL * lv)) / 10ULL;

it works but it need exp 55 instead of 50 to advance level 2
