This question already has an answer here:
In the Avengers (2012), Loki is observed to not have much powers except his sceptre (known as the blue stick of destiny by Tony). We even see that in the final battle, the avengers are fighting the most with the army of Loki and least with Loki himself although Loki is the main villain. Is my understanding of Loki's powers wrong? Or what is it?
