Unit immune to own spells

[Nevanii]

Is there a way to make unit immune to damange-spells that it's casting? For example I want flamestrike to not damage the caster, same for rain of fire etc (i dont want to make caster invulnerable during casting)

A very simple way is to detect damage taken via triggers, check if the damage source (unit dealing damage) is the same as the damage target (unit that will take the damage) and if so, set the damage amount to 0.00
Something like this:

• Untitled Trigger 001
  • Events
    • Unit - A unit Takes damage
  • Conditions
    • (Damage source) Equal to (Damage Target)
  • Actions
    • Event Response - Set Damage of Unit Damaged Event to 0.00

If you are on older patches then you will need damage detection system. If you already imported some damage detection system into your map (even if you are on latest patch), then you should use the system, but the basic idea will be the same.

Does the "not self" targeting checkbox not work for things like Flamestrike's damage?

 

[Nichilus]

No, even with the 'Not Self' flag, the caster takes both the direct and periodic damage.
Just checked the Rain of Fire and it does respect the 'Not Self' flag.
But since there is such inconsistency with the flags, it probably makes more sense to do it globally via trigger.

Thank You Nichilus, setting it via triggers worked fine!
