[Spell] Clockwerk - Battery Assault

[AtivEnergy]

Greetings!
I wish to create a spell that is identical to Battery Assault from Dota 1, and I don't know how to do it in a proper way.
The spell must be MUI.

Spell: When I press the spell:
Discharges high-powered shrapnel at 1 random (or closest) nearby enemy units in 200 AOE around the caster, dealing 25 physical damage and ministun for 0.1sec. That discharges occur every 0.70 Seconds, and the duration will be 10.5 Seconds. 10.5 / 0.7 = 15 times. I need just 1 level for my unit.

Example:

For the moment, I just have the smoke effect on origin..
Abilities\Spells\Human\FlakCannons\FlakTarget.mdl

The help will be appreciated!

Use Unit Indexing to make it MUI, use a Unit Group to track the casters, and use a Timer/Periodic event to manage the casters over time.
On cast -> Add caster to group.
On interval -> Track elapsed time per caster using Arrays + Unit Indexing.
If elapsed time hits the 0.70 second mark then Order a Dummy unit to Storm Bolt a nearby enemy. Reset this time as needed.
If elapsed time hits the 10.50 second mark then Remove the caster from the group.
Toggle the Timer on/off as needed -> on while 1+ casters in group, off while 0 casters in group.
Reals suffer from floating point error so don't check for exact values, use <= or >= in your comparisons. Or just use Integers and count the "ticks".

Hi, Uncle!
Sadly, my brain is still not able to understand how Unit Indexing or Hashtables works..
It is way too complex for me..

I did something random to test, but without a good result.
