Please help with an ability selection system problem

[U_a_ShEkY]

i want to be able to pull off a hard to explain scenerio that seems simple on the whole.

but first ill give some background.

i want to make a World of warcraft map, from scratch. i used to play WoW and now am trying to make a map for it.

i want the heros to be able to spend ability points on certain subgroups of abilities. this is how i want it, (i didnt make a system of triggers or anything, these are just simple pics to explain what i want

ill give it to you in pictures.

Simple Rogue.

rogues have three speccs to choose from in woW. Subtelty, Assasination, and Combat.

i want to be able to let the unit pay a "fee of ability points" to buy a Spec(which is a spell book as a dummy)

but within the book i want them to be able to use ability point (from leveling) to buy the spells in their spec chosen. which is the hard part...

can anyone help me, let alone understand me??????

First of all, there is already a Warcaft III: WoW team developing such a map. Second, without a huge team of people you won't get enywhere. Third, such a system would be hard to implant since you only have 6 slots for abilities.

Sorry if I seem forward but this has been tried soooo often and almost always failed.

Use the speellbook system, and add him a ability like the actual levelup system (The red cross in the right) and make something like that:

- Set a variable to 0
- Unit level up: add +1 to variable
- Unit uses the ability (The dummy levelup): Open a menu with the spells inside the spellbooks saying the actual level and how much point you have (the variable)

So if you click on a button you level up the spell you choosen.
