Solo Dungeons are dungeons that the player goes through alone or with NPCs to receive loot as well as progress through the story. In total, there are six dungeons maps the player must progress through; each of the maps have four levels within them. Depending on how fast you complete a level, you'll be awarded S, A, B, C, D Rank. Failing the level gives you no rank and the level will not be marked as complete. The option to Blitz is unlocked once you reach S Rank Mastery for each of the levels within the dungeon. Players who are VIP 3 can Blitz without waiting for a countdown (CD). Each level costs 1 stamina to play.
