Review Detail of OCspeller in SpiderGwen: I have a system?!

It is an exciting fanfic. Since the setting is the comics world of DC/Marvel Universe, all the characters/references mentioned are easily understood if you have ever read or watched Marvel/DC. Even if you haven't read/watch Marvel/DC, you get a good understanding of the powers granted to the MC. Or else you can do a Google Search and you immediately can picture the hero/villain with a wiki page of their powers. Nice. The system barely makes a showing here except to show stats and granted rewards. this isn't one of those "symbiotic" systems. it feels more like the AI of a game, or a good secretary/butler. Which is good since the focus is now literally on Gwen's development. However, the story seems to develop too fast. I feel she is really reeeeaaaallly OP. By the 15th chapter, she is basically immortal. Not an Undying, but an Immortal. I mean, she literally receives the knowledge and powers of superheroes/supervillains every few chapters, by the handful. One of them had the ability to survive without breathing, and a few had the ability for rapid regeneration/healing. She is developing too fast.
