Celtic Heroes

I was wondering what level you have to be to get 20 max points in a skill, Because I know new character has 5 but i need to know what level you need for 20 , I am level 42 With 15 max skill points in a skill and if you could please post the anwser and if you don't know then post your level and max skill points ONLY if your levels higher than me. Thank you

I think 60 is /20 and 90 is /25. I am 110 with /25. And I'm not sure what /30 is

120 is /30

Thanks this really helped me out
