[Trigger] Siphon Life / Mana

[tml616]

I want to make a custom Siphon skill that is cast and then works for its duration without channeling. I also want it to stack for the caster, meaning:

Caster uses siphon on enemy A
Enemy A loses 10HP/s + Caster gains 10HP/s
Caster uses siphon on enemy B before the siphon on A ends
Enemies A + B lose 10HP/s each + Caster gains 20HP/s
---
Caster uses siphon on enemy C
Enemy A loses 10HP/s + Caster gains 10HP/s
Caster uses siphon again on enemy C before siphon is finished
Siphon duration on enemy C is refreshed but still only siphons 10HP/s

You can do something like:

• Trigger1
• Events
  • Unit - A unit starts the effect of an ability
• Conditions
  • (Ability being cast) Equal to Siphon Life/Mana
• Actions
  • Set Unit1 = (Triggering unit)
  • Set Unit2 = (Target unit of ability being cast)
  • Unit Group - Add Unit1 to (AlreadySiphoned)

• Trigger2
• Events
  • Time - Every 1.00 second of game-time
• Conditions
  • ((AlreadySiphoned) is Empty) Equal to False)
• Actions
  • Unit - Set life of (Unit1) to (((Life of (Unit1)) + (10 * (Number of units in (AlreadySiphoned))
  • Unit Group - Pick up every unit in (AlreadySiphoned) and do (Actions)
    • Loop - Actions
      • Unit - Set life of (Picked unit) to (((Life of (Picked unit)) - 10)

Well, the part that i am stuck with, is when to remove the Unit2 from the Unit Group, so that it won't replenish any more hp for the caster.

How about working with your trigger I do the following:

--Make the spell place a buff on the target for the duration.
--Set the looping trigger to run every 0.10 seconds and remove 1 health.
--Make the looping trigger check if the picked unit has the buff.
--If not, remove it from the group.

This way it would stop when a unit loses the buff or dies. Would that work then?

**Edit**
To keep the 0.10 second loop from running when there is no siphon, have trigger 1 check if the group has units; if so, turn on trigger 2.
Trigger 2 has a check at the end to see if any units are in the group; if no, turn off this trigger.

That is good actually! You can base the spell off cripple, to give it a buff. Then, yes, check the buff, like this (from the second trigger):

• Trigger2
• Events
  • Time - Every 1.00 second of game-time
• Conditions
  • ((AlreadySiphoned) is Empty) Equal to False)
• Actions
  • Unit - Set life of (Unit1) to (((Life of (Unit1)) + (10 * (Number of units in (AlreadySiphoned))
  • Unit Group - Pick up every unit in (AlreadySiphoned) and do (Actions)
    • Loop - Actions
      • If/Then/ Else
        • If (Conditions)
          • ((Picked unit) has Buff (x)) Equal to True
        • Then (Actions)
          • Unit - Set life of (Picked unit) to (((Life of (Picked unit)) - 10)
        • Else (Actions
          • Unit - Remove (Picked unit) from (AlreadySiphoned)

How come i couldn't think of that?
