There are potion cooldowns on every floor that's not Floor 03, the Lobby, or a rest floor.Logging out on any stage that is not a rest stage will end your run, returning you to the Lobby.(And if you enter Floor 01 with any amount of floors remaining that day, even having just 1 floor left, you can just continue that run all the way through. You can only go through 200 total floors a day.The Stupid Timer (how long you can stay in the Tower) has a base time of 10 minutes and can be expanded up to 1 hour and 30 minutes by adding Stupid Pills.You can do Oz with a group, but whether you can interact or team up with others or not is based on the floor you're on.You don't really need much damage (200k will do you fine) until you reach Floor 47.You must be Level 140 or above to enter the Tower of Oz.This guide was written based on information from the current version of the Tower of Oz in the Global MapleStory service (GMS). In other regions, the Tower of Oz may be referred to as The SEED. You can return to the Tower of Oz through the Dimensional Mirror. You can answer Alicia's Soul's call to the Tower of Oz through the quest Tower Under the Sea in the quest lightbulb at Level 140 and above. The Tower of Oz is a 50 floor dungeon consisting of a wide variety of challenges. Unforunately, the Tower of Oz's defense system, which only allows those that have the intelligence of a simple monster to enter, blocks your way! Thankfully, Alicia has Stupid Pills on hand (who doesn't?) which can reduce your intelligence level to that of a mere monster, paving the way for a grand expedition! You must stop Dorothy and the guardians to regain control of the Tower of Oz! However, the Tower of Oz's guardians, whom Alicia created and modeled after her favorite childhood story, grew too powerful for her to control, and are now running omok. With his help, Alicia was able to protect many stupid monster lives from the Black Mage! 800 years ago, Alicia, the Transcendent of Life of Maple World, created the Tower of Oz with the help of the Winter Bard, Ryude.
