-------------------------------------
Now, I'm wondering is there a way to damage units in SS_DMG_Group just once when they get hit by the frost breath and they continue to recieve damage if they stand in the frost splat while it lasts ? Can't think of a simple way of doing this...

1) Your Hashtable isn't doing anything. You can delete it and just check the SS Variables directly. If you want the triggers to be MUI then you'll want to use something like Dynamic Indexing, it's a good fit for this type of spell.

2) To prevent units from being hit more than once you can use a separate Unit Group which is cleared at the start of the cast and maintained throughout. This is your "hit group" which will be checked in the Conditions when trying to damage a unit:

• If - Conditions
  • ((Picked unit) is in Already_Hit_Group) Equal to False
• Then - Actions
  • Unit - Cause SS_Caster to damage (Picked unit)...
  • Unit Group - Add (Picked unit) to Already_Hit_Group

I attached an example map that shows off Dynamic Indexing for a triggered Shockwave. Here are the triggers:

Thanks! I'll go over it and see what I can apply (tommorow, since it's 3am and my brain is , I'll post tomorrow what I'd manage to do)
