If you ever read some game elements novels you should know the basic ones like str, vit, dex, int, wis, luck and sometimes chr, this is something especially important in novels with 'The Gamer' power, like Percy Jackson and the Game; The game we play, the manhwa The gamer etc... but in those types of novel I hardly saw one being focused in luck, yeah I know that lucky doesn't really increase the strength of the mc but I think that it is more important than it is shown, it literally increase your luck and changes your fate! str, vit dex you can basically train, the initial levels of the stats is pretty easy to gain, and using some weights later it won't be that hard, int you would have to basically read books and gain knowledge, wis is rather hard to gain stats into, you have to do wise choices ? as hard as it is, and luck maybe isn't that difficult as you would have to play poker or some other luck games, but from all of them, I think that in real life luck would be the most amazing one, if you have luck enough, it's possible that your won't even have to deal with your enemies it could very well happen that some thunder strikes from the sky killing your enemies, but from all of the few novels that focuses on luck I can't really say that I liked them that much as I think it is hard to create a coherent story based in the luck of the MC. Have you ever read an amazing novel with game elements that focuses mainly on luck ? please recommend it here.
Virtual world white emperor MC has a friend with extremely good luck while the MC himself having an extremely bad luck. Its a really funny story
All I can think of is This MC Is Kickass. Within the game, the MC has a super high luck stat (compared to other players), allowing her to trigger special events/quests.
Invincible Saint -> MC's got "Great Luck-Sensei" w/ him, right from ch. 0 Cultivation Chat Group -> to be invited by mistake to such group... (0_0i) Demonic King Chases His Wife -> MC's luck is too much that makes me think it's the plot armor Last 2 don't have games elements though
