No no no! A leak is when you use too many Triggering Unit or All units in Region commands. It's better to use variable arrays, because every time you use one of those commands, WC3 makes a new variable for it, and the more you use it, the laggier things get. With variable arrays, the data from previous casts are overwritten so there's no 'leakage'.
This spell sucks! The triggering is GUI, LEAKS, AND IS INEFFICENT! How long such a spell take you to make? 15 minutes?
Mine was better I posted in the map fourm. In mine it was multincastable by using locals and did not leak and the code was WAY better than this.
And WT# is with a if then command for every spell level? YOu ever heard of maths? You can use mathimatical fomulars to make AOE go up with spell level or even stats!
I strongly reccomend no one use this spell! It will only add unescary filesize, lag, and leakage. . .
And also the map is cheaply finished off (says it was made by "Unknown" and has no discription.)
