How to make AutoCasting

How to make AutoCasting

Is there a way to make normal spells like Mana Burn, Banish or w/e auto castable?

Though I'm not positive, I'm fairly sure you can just use a base spell with autocast (Fairie Fire for example) then modify it to cast bash.

The only other way I know about is to do a dummy unit, which might actually not be all that hard, but whatever.

Anyway, let me know if using a base autocast spell works.

I have no idea how to modify a base auto cast spell to an other spell but I think I know how to work with a dummy just like this:

Event - Whenever a unit begins casting an ability
Condition - Ability being cast is equal to Dummy AutoCast Spell
Action 
- Create 1 Dummy unit at position of Casting unit Facing default building angle
- Order last created unit to cast demon hunter mana burn on target ability being cast.

Well not sure if it looks exactly like this (my english isnt very good) but I think it works like this.

Thx for the idea

Event - Whenever a unit begins casting an ability

should be

Event - Whenever a unit begins effect of an ability

But that doesnt interact with

Condition Ability being cast equal to..

Does it?

It does.

Oh ye your right nvm
