The League Tower is a special Event that allows League Members to work together by fighting the Corrupted with their Champions. The Tower is split into floors. The Corrupted are malevolent creatures who patrol these floors. Send your Champions to fight them to get Champion XP and incredible Rewards. You will need to defeat all of the Corrupted on each Floor in order to progress to the next one.
The Event is time-limited. League Members send Champions to clear Tower Floors. Each Champion Type can be sent only once. After a particular Champion Type is sent to the Tower, it is blocked from being sent again unless you use a Champion Type Unblocker. You can only unblock each Champion Type ONCE. This means that if an Unblocker is used on each Champion Type, you’ll be able to send a total of 30 Champions of different Types to attack the Tower during one single Event.
The higher the Floor, the stronger the Corrupted you’ll encounter there. Higher Level Floors will need to be cleared with Champions of higher Rarity Grades. Each Tower Floor contains a certain number of the Corrupted. Some Corrupted have an Element, others don’t. If your Champion's Element beats a Corrupted's Element, your Champion will receive a 25% Attack Boost in the battle. If the Corrupted's Element beats your Champion's Element, or if the Corrupted does not have an Element, no Bonus will be applied. The Corrupted cannot receive elemental bonuses in the Tower.
Rewards you receive for clearing Tower Floors can be divided into 3 types:
- Personal Reward. You receive this Reward for defeating the Corrupted on the Tower Floors. This Reward is the same as the one players receive by defeating Undead in the Champion window.
- Milestone Floor Reward. This Reward is given to Leagues upon successfully clearing a Milestone Floor. To receive this Reward, each League Member must defeat at least one of the Corrupted within a given number of floors.
- Special League Reward. This Reward is given to a League that successfully clears Floors 30, 50, and 100. To receive this Reward, each League Member must have defeated at least one of the Corrupted during the current League Tower Event. Rewards gained during the League Tower Event can be claimed once the Event has ended. Exceptions are Champion XP and Energy gained in battles with the Corrupted, which are added to your account automatically.
