your only meant to have 1 specialization point per level, you cant use two.
to address what your probably talking about, if you cheat and give yourself more points, you wont be able to give yourself x amount of points depending on level.
so lets say your level 20, that 1 point.
21: 2 points in what ever skill
22: 3 points in what ever skill.
so if you wanted to put 10 points into a skill then you need to wait to that allocated level.
whatch out though, if you give yourself allot of points. rather than getting one per level, if you used 15 points, you will have to wait 15 levels before you can spend points again. softlocking yourself out of using it. Ask me how I know.
