Movement detection and slow spell help

[Darkshine]

Hello, i have some questions:

1. there is some method to detect the movement of a unit? I mean, if a specific unit is moving or is stopped. I want to do a an ability where the hero gains bonus damage and armor when is stopped and lose it while it is moving.


2. i plan to do a skill (for the same hero) where it creates a ''ring'' of slow around it. Precisely, at 300 ranged. So, up to 300 ranged from the hero, nothing happens. At 300 - 400 range, there is a slow aura. There is some way to do this? I think, maybe, stacking two auras for this.

Any help will be welcome ^^

2. Every 0.2 seconds or so, pick all units in 400 range of the unit. If the distance between the aura unit and picked unit is less greater than 300 and the picked unit doesn't have slow buff, then create a dummy unit and order it to cast slow on the picked unit.
