Sifu got any recommendation to a zero knowledge newbie how to start this journey in create item in dota2 workshop? I saw there many videos from youtube, but I am blur and like know the proper sequence of learning this in creating item or arcana.

some addition questions:
- dota2 workshop is free or need to buy?
- what are other software require to use?
- is this 1 software to use to create all items and arcana effect? or need few softwares in creating different type of item? what are they?
- i watched video some modified Anti Mage weapon; means can we changing color or modify little on default item and consider it as new item? eg: white tiger of mirana or flying tiger?
- why no one copy blizzard dota1 heros aura effects into dota2?
