Radiant Mode

Radiant Mode is a mode in Hollow Knight. In this mode you only have one mask and you cannot upgrade that number as unlike the regular mode and steel soul, there are no mask shards on the map. You also cannot upgrade your health using charms. It opens up once you fight all of the radiant mode bosses in Hall of Gods or when you complete steel soul mode. If you choose this mode you can choose whether death is permanent like in steel soul mode or not. The ability to focus soul as well as charms relating to health, focusing soul, etc are removed entirely because they would be rendered useless either way. Charms that were originally fragile are also removed if you choose death to be permanent because they could be used throughout the game and their fragile status would mean nothing. The overcharming function is also removed as well because double damage wouldn't matter. Another aspect removed from this mode is the Delicate Flower quest. Because in this quest you cannot take a hit, it becomes meaningless seeing that that is already the objective of the game. Because you die after one hit, bosses and enemies that originally did two masks of damage will be made harder in other ways such as harder attacks or a harder arena. Because benches no longer have the use of regenerating your health, they instead regenerate soul from the beginning of the game, without having to get Salubra's Blessing which is removed.
