Just go with:

Weapon DMG > INT > DET > Speed/Crit

Crit will even its usefullness out the more you get of it, spell speed is only useful to a certain degree as well - Example: Abandoning 30 crit which gives you around 1%+ of crit rate is not worth casting 0.01 seconds faster, if you're too fast you'll loose time in ice transition if you have to wait for ticks etc.
Det will increase your crit and speed values, b/c you get more base dmg which is increased by crits and speed - same for WD and INT - all stats below benefit from the higher ones.

Just one thing you should look out for, there is generally only two ways to make a good Novus build, or you'll loose out bonus points in the Lower stages:

44 Main stats - 31 offstats aka. 44 speed/crit 31 det - this will give you + 9 points offstat on zodiac (49/35)

or the cheap version which i went with:

36 crit 24 det 15 speed (or switch the speed and crit, whatever your gearset is lacking more) - this will give you +8 stats offstat on zodiac (40/27/16)

In the end, if you dont care about the money go fullstats - if you dont want to dump millions into your weapon like me, go with the second one so you dont loose out later

Anyways - gl with the future stages and the light grind
