Viewers Note:
A very decent and original idea. I like it, especially the work with effects.
It is well coded, I can see no flaws. The only thing I can oppugn is your coding style... for example your globals. 1 row -> global, 2 row -> comment etc.
I dislike using another row only for comments, that makes it for some people unclear, it would save lines to just put the comments behind the matching global but well, it is everyones own coding style

Ability tooltip is the standard wc3 ability tooltip what every spell should have at least.
MUI, vJass -> extra score.
All in all, this spell deserves a highly recommended.
It is just an idea...but wouldnt the spell look even better if it was like immolaton or manashield? Switching it on/off with mana drain overtime? :P
Well, personal taste ^^ GJ
