Make a level-based mastery class system.

• This system will have different quests for each class, and these quests will reward each completion, which will be in the form of ability upgrades and/or additional tools that vary depending on the class.

• These quests will be repeatable and become increasingly difficult each time they are completed.

• Quests will have a limit, and upon reaching this limit, the class will gain a new ability with or without additional tools.

Note: The rewards will be better and more numerous if the class is more expensive.

This, in my opinion, will give players an extra purpose to play beyond simply earning bonds. Thank you for reading:)
