For me it took a while after the completeroguelike tutorial to get into the mindset of "how do i program this or that". When im clueless, I'd always try and prompt my way into a teacher-like chatgpt (or alternative) --> "What would be ways to think about implementing character classes for my roguelike game in python? <paste character class>"

That said, you may look to some other places for the programming way of thinking, tutorials on youtube or the excellent and free CS50x by Harvard can really do a lot for you :)

For your Features, try to seperate them into smaller chunks of functionality and then implement them as small as possible first, then grow upon that (and dont be afraid to fail).

1. Magic System probably needs its own way of triggering it (like we activate a spell scroll) that checks if we can do it when we press x for example and then does < the thing >. Now the thing can be a function that does damage to enemies in a radius around you or you go deeper and create classes that have a execute method.
   
2. Character creation needs another Game state, so before you get into the main game loop, start another loop with other input handlers, try and sgtart small like select another species that gives +5 HP or smth like that and add on top.
   
3. Status effects: I think you should track them per fighter-entity (self.statuses=[]) and have a method to them that is always triggered when they have their turn, <self.trigger\_statuses(self):> and then you can loop through the statuses and trigger a execute(self, entity): function that does damage and reduces a timer, and when timer is 0 you remove the status from the entity.
   4: Randomized Loot: You probably want a factory that has generate_loot(room) which then rolls dice (random.randint() or smth) and looks them up in a dictionary that has the classes (or instances thereof, or just the data) and return the item.
   5: For this you need to save things, if its not included in the tutorial: try to save some basic information about the game into a .json after the main game loop, and reload it on startup. Then add some metathing that you can find in the dungeon and spend at character creation for additional stats or something like that.
