soul burn damage

Im making a custom buff system where I have made soul burn into a buff called Paralyze which disables skills.
However, after 1 second units affected by paralyze dies. I think it has something to do with these fields:
Data - Damage Amount
Data - Damage Period

What should I set those to in order for the spell to make no damage?

Well if you want no damage than set Damage Amount to 0.
Damage Period is how often the spell inflicts damage. Set to the duration of the spell just to be safe. 0 makes it hit awesomely fast hence the insta kill.

If you want instant damage at the start just set Damage Amount to how much damage you want it to do. While setting Damage Period to the duration + 0.5 seconds or so. Or you can just trigger it.

damage period longer then buff duration and no damage will pass.

ps. dont you have hand to test it self?
