Adding an Ability Level

[CrackUps]

Im having trouble adding another level to an ability on DotA. The ability is Techies Remote Mines. I've changed it so it's no longer his ulti and have decreased the damage but I need to add a 4th level to it. I'm having trouble doing this I'm not quite sure what I must do to add it in, i know i obviously have something to edit in the war3map.j file. Could somebody please explain to me what to do and what else i must edit for example the .slk files and AbilityFunc and AbilityStrings files.

Well I'm no good with JASS. But couldn't you just use the WE and then convert it into jass? I means thats what the "convert to JAss" button is for isn't it? Just make the spell and tell it to go to level 4? Then convert it to jass and work from there changing what you know you want changed and leave the part that says " LEVEL 4!" ?
That's about all I've got.
