There's a number of issues with the ability that need to be addressed ontop of what Meatmuffin has mentioned:
- It only works for one unit type
- The decoy is an imperfect duplicate making it easily detected by selecting it and has no option of being a perfect duplicate
- The configuration is very limited, as Meatmuffin mentions more things should be able to change each level (needed to be re-iterated)
- Decoy has fixed stats (health being most notable)
- The ability is exceptionally simple from a scripting perspective, I couldn't award it a particularly high rating as a result
Other (suggestions):
- The primary part of this spell is windwalk with a bit bolted on to it which is a neat extension but not encouraged due to being object editor based, that is to say if fully scripted then people can use any dummy ability or any other extension they wanted (e.g. adding passive critical strike)
- Quilnez created the very useful
GUI Custom Illusion which essentially does the same thing (scripted mirror imaging) minus the animation and damage at the end but works for any unit. I'd recommend using it as a base for the ability instead of the very flawed current method - there are other similar systems on the hive if I recall correctly
Edit: on a totally unrelated note that description is a bit painful to look at, notably using that blue (
This colour is exceptionally hard to read, exacerbated by the very bright animated titles, I suggest going for something a little less 1990s-internet generally for descriptions
