[General] What spells are cast in a group vs. are cast per unit

What spells are cast in a group vs. are cast per unit

Is there a place where it is described?

For example, rain of blades, if you have selected 3 units, all three will launch it when you press the button.

However blink will only be released by one of the units.

Well, it's easy to trigger it, but you need use Jass because GUI doesn't let you issue any order:

• Trigger 1
  • Events
    • Unit - A unit issues an order with an object as a target
  • Conditions
  • Actions
    • Set TempGroup = (Units selected by (Triggering player)) //I think triggering player should work, if not, use (Owner of (Triggering unit))
    • Unit Group - Pick every unit in TempGroup and do actions
      • Loop - Actions
        • Custom script: call IssueTargetOrderById( GetEnumUnit(), GetIssuedOrderId(), GetOrderTarget() )
    • Custom script: call DestroyGroup( udg_TempGroup )

• Trigger 2
  • Events
    • Unit - A unit issues an order with a point as a target
  • Conditions
  • Actions
    • Set TempGroup = (Units selected by (Triggering player))
    • Set TempLoc = (Target point of issued order)
    • Unit Group - Pick every unit in TempGroup and do actions
      • Loop - Actions
        • Custom script: call IssuePointOrderByIdLoc( GetEnumUnit(), GetIssuedOrderId(), udg_TempLoc )
    • Custom script: call DestroyGroup( udg_TempGroup )
    • Custom script: call RemoveLocation( udg_TempLoc )

• Trigger 3
  • Events
    • Unit - A unit issues an order with no target
  • Conditions
  • Actions
    • Set TempGroup = (Units selected by (Triggering player))
    • Unit Group - Pick every unit in TempGroup and do actions
      • Loop - Actions
        • Custom script: call IssueImmediateOrderById( GetEnumUnit(), GetIssuedOrderId() )
    • Custom script: call DestroyGroup( udg_TempGroup )

These examples are just to give the idea, you have to add more details you wanna.
