Cannon fodder

As said, the Ancient One is extremely powerful, which explains why Kaecilius and his minions didn’t stand a chance in the fight from the beginning of the movie. So, no matter how powerful they were, the Ancient One would have defeated them.

However, how did Doctor Strange defeat them in his first fight? Was Kaecilius followed by the most useless minions? I know he wasn’t, because they helped him defeat the Masters of the Sanctums…Why did they become stranded, as if they had no means of teleporting back into the Sanctum Sanctorum? It isn’t as if their special rings ran out of power…

And how did Stephen Strange defeat Lucian in the astral plane using electricity?!? Don’t tell me I’m the only one baffled by that scene. I guess they wanted to give Scott Adkins a bigger role, but they didn’t know how to have him lose against Benedict Cumberbatch…
