How does a monkey to start Dota2 Modding

My goal is to create an infinite bouncing Luna moon glaives.
1. Just to change mechanisms.
2. No FX required.

Progress:


All I have to do:
1. Get mod working
 --  Myll's getting started really helped.

2. Get to know how to customize an ability ( Data driven ability,  Key value and Lua script )
-- Noya's Beginner's guide is cool.

3. Oh my god.. I can't just change a parameter to let moon glaives bouncing 666 times..
    Shall I reinvent the wheel?
-- All works had been done by MNoya's Sepll Library! Thank to open source!

4. Umm.. this wheel doesn't work.
-- Seems after dota2 modkit merged all document, everything goes wrong..
-- Taking time to check it out later.
