Awesome looking post: outstanding detail and presentation! However, it's not, in fact, a valid submission. Remember to physically attach your hero map (.w3x) to the post before the conclusion of the contest.
Nope:
For everyone that's considering the implications of adding a fourth level to any of their hero's spells, just try to keep them balanced by either altering the spell's upgrade criteria, making the fourth level a very small enhancement, or spreading the power from three levels (33/33/33 %) to four (25/25/25/25 %).
Additional innate hero abilities outside of a hero's spell capabilities will likewise require balancing, reducing the power of a hero's spell book to offset the added special ability.
Also, heroes that progress past level 10 would be grossly unbalanced with existing Warcraft III heroes. Remember, the goal of this contest is to create an effective, original, BALANCED hero, not simply one that's "uber-powerful."
