How to make a damage over time trigger?

[darkloladin]

Im trying to create a trigger enhanced spell of something like envenomed weapons and every 3 seconds the buff deals damage = 3x agility.

First, create 3 variables: CastUnit (unit variable), EffectedUnits (unit group variable), and AgilityVar (integer variable). Then just follow the triggers

• Trigger
  • Events
    • Unit - A unit Finishes casting an ability
  • Conditions
    • (Ability being cast) Equal to EnvenomedWeapons
  • Actions
    • Set CastUnit = (Triggering unit)
    • Unit Group - Add (Target unit of ability being cast) to EffectedUnits
    • Set AgilityVar = ((Agility of CastUnit (Include bonuses)) x 3)

• Damage
  • Events
    • Time - Every 3.00 seconds of game time
  • Conditions
  • Actions
    • Unit Group - Pick every unit in EffectedUnits and do (Actions)
      • Loop - Actions
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • ((Picked unit) has buff EnvenomedWeaponsBuff) Equal to True
          • Then - Actions
            • Unit - Cause CastUnit to damage (Picked unit), dealing (Real(AgilityVar)) damage of attack type Spells and damage type Normal
          • Else - Actions
            • Unit Group - Remove (Picked unit) from EffectedUnits

I dont know if this is completely leakless, so if you have a problem with it, just tell me.
