Level any new character to 45 within three weeks and get exceptional rewards.

With the launch of Unchained on March 2—and the new Warlock class—we’re challenging everyone to level up a new character before March 23, and get some incredible rewards when they do.

Any character that is level 10 or under when Unchained releases on March 2, and that reaches level 45 before maintenance on March 23, will receive an upgrade bundle and first chance at the Temptation costume.

The upgrade bundle includes all of these non-tradable items:​

• Warrior’s Tokens x30
• Siren's Emblem x20
• Pirate's Emblem x20
• Hongmoon Unsealing Charm x15
• Naryu Silver x10
• Element of Luck x5
• Lucky Jewel x5

Temptation ​

Your first character of any class that meets the criteria of the challenge will earn the costume and the upgrade bundle, which will be sent to your account-wide Received Items tab where it can be claimed by any character. While the upgrade bundle is only able to be earned once, we’ll grant additional Temptation costumes for any other characters that complete the challenge on your account.

The rewards will be distributed at defined intervals throughout the leveling challenge, and characters that were level 10 or under—and reached level 45 before server maintenance on March 23—can expect to receive their rewards the day after maintenance each week (March 10, 17, and 24) following when they hit level 45. The challenge rewards will be sent to the account-wide Received Items tab, where it can be claimed by any character on the account.

We hope to see many of you taking on this challenge, and earning some exceptional rewards. Good luck!​
