hoard yuor skill points until you can add them to the attribute you are training and you can take it over the next ability soft cap you can find soft caps here.
http://www.glbwiki.com/index.php?title=Ability_Softcapsyou can not really give an exact time frame because the variable change. You are training your attribute plus you are recaiving ALGs every time you level up. so horde yuo skill points abd after every time your LB levels do the math quick
find the value of SP Per Attr. for your current skill level then use the following formula... Current level of skill + (Skil points/ SP Per Attr.) if the result is larger than the value in the Max Attr. Value then it is time to add the skill points
Example 1 New LB is starting out I have Agility at 25 and 15 SP because I did not place them yet since my value is between 0.00 and 48.06 my SP Per Attr. = 1
my formula is 25+(15/1) = 40
since 40< 48.05 I do not add any skill points to the attribute.
Example 2: New LB has leveled up twice and now is a level three LB in that time the owner has trained him in agility so that he leveled up once. his natural agility score is 27 and there is now 25 skill points to spend.
27 is between 0.00 and 48.06 my SP Per Attr. = 1
I apply the formula 27+(25/1) =52
since 52 > 48.05 I should put my skill points into agility now unitl it goes over the cap.
Example 3: New LB just put 22 SP into Agility and now has an agility of 49. He has 3 skill points left.
49 is between 48.07 and 60.51 so my SP per attrib is now 2
I apply the formula 49+(3/2) = 50.5
50.5 < 60.51 so I should save my skill points.
