    • Unit - A unit Begins casting an ability
  • Conditions

Trigger runs when player stops casting spells.

• MindStaffHasar
  • Events
• Unit - A unit Finishes casting an ability
  • Conditions
    • ((Casting unit) has an item of type Claws of Attack +15) Equal to True
    • ((Target unit of ability being cast) belongs to an enemy of (Owner of (Casting unit))) Equal to True
    • ((Unit-type of (Target unit of ability being cast)) is A Hero) Equal to True
  • Actions
    • Unit - Cause (Casting unit) to damage (Target unit of ability being cast), dealing ((Life of (Target unit of ability being cast)) / 10.00) damage of attack type Chaos and damage type Unknown

Trigger does not work.

How can i make a system like this?
When the player actually starts casting spell?

I don't know what you mean by a system since nothing of these triggers look like one.
You use Starts the effect on an ability, not Begins casting an ability.

It does not work too. Somehow still it runs the trigger. Here is the original trigger.

• MindStaffHasar
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • ((Casting unit) has an item of type Mind Staff) Equal to True
    • ((Target unit of ability being cast) belongs to an enemy of (Owner of (Casting unit))) Equal to True
    • ((Unit-type of (Target unit of ability being cast)) is A Hero) Equal to True
  • Actions
    • Unit - Cause (Casting unit) to damage (Target unit of ability being cast), dealing ((Life of (Target unit of ability being cast)) / 10.00) damage of attack type Chaos and damage type Unknown

Update: MY BAD, THERE WAS ANOTHER TRIGGER INTERFERING. Solved.
