Changing Spell Cost, please help

Well I really need to change the spell cost on some hero abilities, and since I can't do it with the World Edit Blizzard has provided, I need help. What tool would be best for my purpose? And can you give me a quick explaination of how to change spell cost with the tool you recommend? Thx for the help.

For a map, it is impossible for now. Of course you can create a custom MPQ using a modified uniabilities.slk (this is the file where the spells properties are). But this approach would make this a "game-custom", not a map-related stuff. And game-customs require all players of it to be running the same modified MPQ.

Well I have made a trigger that enforces the mana cost I want for a spell, the only problem is I can't make it display the changed mana cost. All I really need to do is change the subtitled text so people know how much the spell costs instead of just clicking on it woundering why it's not working. So is there anyway to change just the number displayed?

well, edit the profiles for that spell and add it to w3m =)

And one would go about doing this how?

hmm try edit the humanabilityfunc.txt and such

What editing tool would best suit my purpose?

The "func" files (humanabilityfunc.txt , undeadabilityfunc.txt etc) are all text files and require nothing other than notepad to open and edit.

You will need an mpq extractor to remove a copy of the text(s) from war3.mpq, as well as a program (such as mpq2k) to put the edited func file(s) into your map.

thank you :)
