Welcome to Hidden Street:D
To answer you're question you need to keep putting points into Luk until it's 3 higher than your level. So if you where level 38 then you would need 41 Luk. So the level which your Luk would 3 higher than your level would be level 47
39=11 Luk /195 Int
40=16 Luk /195 Int
41=21 Luk /195 Int
42=26 Luk / 195 Int
43=31 Luk / 195 Int
44=36 Luk / 195 int
45=41 Luk / 195 Int
46=46 Luk / 195 Int
47=50 Luk /196 Int
So by level 47 your stats should be correct to that of a luk wizard
I hope this has answered your question.
Ice wizards FTW :)
