Thanks for the submission, there are a few notable issues I'd like to address in the spell:
- Configurable values that do not change on a cast-by-cast basis should be in their own trigger (this avoids pointless operations to reassign values to the same value)
- Dummies should be owned by a neutral player as to not mess up the scorescreen
- Dummy unit type should be configurable as should effect models and other similar things
- You leak a point (position of Cs_Target)
- Use temporary variables to store references used more than twice (e.g. triggering unit, last created unit, etc.)
- floating text should be optional as there is a texttag limit imposed on every player of 100 (meaning this could interfere with other texttags used by a map)
- Your documentation doesn't make a lot of sense (I gather that English is not your first language so that is understandable, though it's extremely confusing to read)
- Why remove the units if their health is lower than the damage dealt? surely they should take the damage anyway (for example if a hero is removed from the game this way it can not be revived)
- Lacks a version number
- Needs a proper description
Because of these above issues I'm setting this submission to needs fix, I'll be happy to re-review your work once you've updated it. If you have any questions do not hesitate to post or send me a PM (Private Message)
