Achievement has been discontinued due to the server shutdown. It's impossible to unlock this now. Challenges are no longer available.

Challenges are found from , then . Champion challenges will mention a hero by name. Each day, there will be one new daily challenge for Karlsnor. There are also a small number of permanent ones.

Most daily challenges are something like "Kill/Damage X enemies with a certain attack." You may need to level Karlsnor up to unlock certain attacks. I recommend doing this is crossroads. You might be able to complete the challenge in a user-made world, but that can be buggy.

You'll need to play on 20-50 days for 5-15 minutes to unlock this achievement. I didn't get it until the day after Karlsnor reached level 20.
