Doom Tower Explained

The Doom Tower is 120 floor challenge that resets every month and can be played once you reach level 40 player level.  Each floor contains 3 waves of enemy champions with every 10th floor having the 3rd wave be one of 8 bosses.  You will receive a one time reward for completing regular floors and secret rooms.

There are currently 2 difficulties for The Doom Tower, normal and hard.  Most players who are able to complete dungeons such as Ice Golem and Dragon floors 15+ will be able to wave clear the floors without too much difficulty, but may struggle on some boss mechanics depending on your champion selection.  Normal enemy champion levels is in the 150-180 range.  The real difficulty comes in the boss fights and the boss’ mechanics.  Once you move on to the hard difficulty, you can expect a much harder challenge.  The enemy champion levels rise to 250-350 and they have increased speeds and resistances.

At each days daily quest reset, you will receive 10 gold and silver keys for The Doom Tower.  You can also aquire 5 more silver keys through the completion of an advanced daily quest.  Gold Keys are used when you attempt to climb to an uncompleted floor of The Doom Tower. Silver Keys are used on secret rooms and to replay boss floors for additional rewards. Failing a floor does not consume a key.  This allows you to try out different strategies on floors you are struggling with. If you use all your keys every day you will be able to complete The Doom Tower in 12 days.

Secret Rooms

Each of the difficulties contains 12 secret rooms.  These rooms follow similar rules to the regular floors of The Doom Tower, but have additional champion restrictions on them which can make them more difficult.  Some of the restrictions include only using champions of a specific rarity, champions of a specific faction, or even champions of a certain affinity. Once you complete a secret room, you will be given 2 silver keys and champion fragments towards the current Doom Tower champion you are collecting. Each secret room will give 2-3 champion fragments which means it will take approximately 3 months to unlock each champion. You can see the current secret room rotation on the Secret Room Guide page
