Rating Difficulty: Normal

Attain character level 90. This challenge still counts even if your character dies afterwards.

This.... requires a decent build to do. It requires around 2 weeks to reach this level, depending on how long you spend on the game each day and your skill level. If you are willing to spend a bit more currency to do more exp-rewarding content such as beachheads or breachstones or Zana map-modifiers, you're gonna level pretty fast. But of course, these strategies require at least a decent build that doesn't die too often …
