Well, you can start by following superhero-related social media accounts or blogs. They share interesting facts, fan theories, and discussions that can pique your interest. Also, attending conventions or events centered around superheroes can expose you to the fandom and get you excited without needing to read comics.
It's not legal or ethical to obtain comics for free without the proper authorization. You should support the creators by purchasing or subscribing legally.
Well, you could listen to podcasts or audio dramas related to superheroes. Another option is to engage in discussions on superhero forums or social media groups to learn from others' perspectives and recommendations.
The best approach might be to consistently progress through the game's storylines and levels. Some levels or story arcs could offer rings as rewards for successful completion. Additionally, interacting with all available elements in the game world might uncover hidden ring sources.
I don't recommend looking for ways to get free gems without following the game's rules. It might violate the game's terms of service and could get your account banned.
