More than 5 hero abilities.

You see I am making a map where players can choose multiple rewards for leveling up.
Among these are your usual "learn next level of spell".

As much as I can id like to keep both spell levelling and other assorted rewards in the same interface.
Which brings me to the question, is it possible by any means to give ahero more then 5 learnable abilities?

Nope, wc3 hardcoded.

I use a window system for that.

As awesome as that system is Id still like to have a single Spellbook.

Anyway Ive scrapped the idea of using hero learn skills.
Is it possible to add requiremnts for each level of an ability?

Single spellbook? what do you mean?

The 8heroskills thing uses two pages it is simple enough, there's not a lot of spaceanyway in the command card.

I don't think it is possible to have specific requirements for each level.

Well what i meant was that you have single spellbook.
Which has 11 buttons, 4 of them are your normal hero skills the other are just random upgrades.

All Im actually looking for is to allow the above system to scale and mimic hero levelling.

You could easily make the hero have 0 hero abilities, then make a fake 'learn abilities' spellbook, with the same icon, and with up to 11 learn icons in it.
Then on cast detect it, and level up/learn the ability as appropriate.

Can spellbooks have "charges" though? (That is, you'd want the dummy spellbook to display a "1" in the lower-right corner on hero level-up.)

If so, then great!

Shift and double click the "Abilities - Hero" line and put there the raw codes of your abilities.

Does that trick really work with learnable abilities aswell?

No.

I doubted it. Else why would all do Skill Tech Trees etc?

Have multiple spellbook abilities, each with a different imported icon.

This is an expensive solution, but it would definitely work.

Why not using an ubersplat? :D
