Units in a region getting healed when percentage-life = lower than 50%

[Inspexor]

I'm trying to add a trigger to my custom map where units in a specific region or units that are in range of the healer get healed by the healer when their percentage life drops below 50%.
However it seems like i can't find the right triggers.

I was thinking about something like:

Event: Every 2 sec

Condition: Unit's life in region X/in range below 50%

Action: "healer" casts "healing spell" onto unit with health below 50% in region X/ in range

----

If there are more than 1 unit with 50% health i guess i'd have to say "cast healing spell onto random unit [...]"

i'm too much of a noob to know how to set this trigger up, i basically know what to do but i can't handle the details yet.

can you help me?

Will there be only one of this healer units?

yes, it's like a mini-boss fight

the overall idea is:

• Get Healers Position/ is not needed if you use the rect version
  
• Save possible targets in an unitgroup
• Filter the unitgroup (%Life,dead,allied)
  • this is done either by using matching conditions in the group finding with matching unit
    
  • or by looping the group and use an if and remove units from the group with picked unit if the fail the conditions
• Order your healing spell.

• Some stuff
  • Set Loc = (Position of Healer)
  • Set Group = (Units within 800.00 of Loc)
  • Einheitengruppe - Pick every unit in Group and do (Actions)
    • Schleifen - Aktionen
      • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
        • If -Conditions
          • Or - Any (Conditions) are true
            • Conditions
              • ((Picked unit) is dead) Equal True
              • ((Picked unit) belongs to an enemy of (Owner of Healer)) Equal True
              • (Percentage life of (Picked unit)) Greater as 50.00
        • Then - Actions
          • Einheitengruppe - Remove (Picked unit) from Group
        • Else - Actions
• Unit - Order Healer to Human Paladin - 'Holy Light' (Random unit from Group)
• Custom script: call DestroyGroup(udg_Group)
• Custom script: call RemoveLocation(udg_Loc)

Inside the triggers condition you should place nothing concerning the group (location based).
