Speak with the Battlemaster to enter the staging area. Upon entering, Corrupted Night Walkers will begin attacking; defeat them for a chance to receive a Corruption Key. Speak with the Corrupted Guard upon receiving a key to enter the first level of the dungeon. There are 10 levels in total, and each successive level comes with a more challenging set of monsters and a final BOSS.
You have 5 attempts per day. After you get a key you can enter the dungeon, and a key is needed each time you enter. Keys can be collected all at once and regardless of attempts left for the dungeon, and are only obtainable by killing the Corrupted Nightguards within the Corruption (Lobby).
Enter Corruption (Lobby) by talking to the Battlemaster in the times between 10:00-11:00 and 19:30-20:30 Server Time. AFK is disabled for this map. Cannot enter map in party. Talk to ??? to enter the Corruption L1 with a Corruption Key in your inventory.
Enter the dungeon, talk to the Battlemaster to enter the battlezone, kill the Corrupted Reapers and Corrupted BOSS. Talk to the Corrupted Envoy to move onto the next level, collect the level pack for that level (cannot move on if this option is selected), or return to Starglade. Corrupted BOSS drops Lionheart Banner Materials.
Every level's Corrupted BOSS holds the chance of dropping a Lionheart Stone. Each level's Corrupted BOSS also drops the corresponding loot:
|Corruption L1||Outstanding Lionheart Essence x1|
