Diluc is one of the 5-Star characters in the game. There is no story way or an open-world way to unlock this character. The only way to unlock Diluc is up to complete a chance. Players will need to make wishes using the Acquaint and Intertwined Fates. Since Diluc is a 5-Star character, its only a 0.6 chance of pulling him from that banner. Also, the Fate items are extremely hard to come by as the developers are hoping players will put money into the game to buy more. This is likely the only way players will be able to unlock Diluc at a reasonable pace. Those who don\’t wish to spend the money will have a much harder time getting Diluc from a wish. Although, it is completely up to chance.
Genshin Impact is so much more than another gacha title created to suck the money out of your wallet (even though it is). There is so much to do in the game without needing to spend any money to enjoy it. It is surprisingly one of the best games to release in 2020. It will likely be around for a very long time with new updates releasing in the future.
