Can Item Abilities be Converted to Hero Abilities?

I am working on a map right now and I want to know...how do you convert Item abilities to hero abilities? I want to give a hero a Spell Book (TFT item-allows you to cast a few minor spells without knowing them)- style ability as an ultimate, but I can't get it to become an ability...please help if you can.

You should copy the original spellbook ability in the abilities tab (special->item) and paste it as a custom ability.

Uncheck 'Stats-Item ability' and check 'Stats-Hero ability'.

Set 'Stats-Required level' to 6. Add whatever spells you want and then set 'Data-Maximum and Minimun spells' to the same number of spell in total (the 3 default spells and whatever you added.

'Art-Button position-normal(X,Y)' should be 3,2 respectively.

'Art-Button position-research(X)' is 3.

Thats it.

I've recognized that passive item abilities doesn't get any button but they still work. You can also make an aura that does nothing and place tootips and thing in the aura instead...

The sad thing about the FT abilities editor is that you can't make a new ability from scratch. It would always be based on an existing ability.

A Deathpact + Raise Skeleton spell would be nice. I suppose triggers would have to do for the moment.

Well, it has to be based on something. The only purpose I could see in doing brand new no predata spells would be to use item abilities and/or have multiple abilities in one spell.

Exactly. This would allow me to create a 'Great Gospel'-type ultimate, without using triggers. Besides, making new (or rather, semi-new) spells is why we got this in the FT editor.
