Scorpion, as far as I can tell, is an atypical Chinese author who doesn't focus on the complexity of combat in his maps but rather prefers to create challenges for the player outside of battles. I judge this not only by "New Splendid World," but also by this question from N Iko regarding "Light of the World," and by Glenn's walkthrough of "Perfect World." Plus, the author's style is characterized by impressive visuals.

Regarding the final battle in "New Splendid World," if I remember correctly, the tactic there boiled down to the following: it was necessary to defend behind a power field with the azure dragon and snipers so that the enemy fairies would spend all their spells on the snipers, whom we regularly resurrect; that is, the fairies should not have access to 4th-level magic, otherwise the azure dragon would die. After the fairies had exhausted their spells, we raise a stack of snipers (fortunately, there is enough mana) and under Frenzy, we shoot everyone down.
