Play on a harder difficulty – after making their way through all three acts of Torchlight III, players have probably learned a lot about how the different systems of Torchlight III interact with each other.
Players can and should try out a different relic as well on a new character.
There is also the relic system, which basically acts as a secondary class. Upon switching to the relevant class, they will be able to try out the new gear once they reach the appropriate level. Also, as items can be shared by characters on a single account, players have likely amassed some unique weapons and armor that their current class cannot use.
It helps that maps are randomly generated as well, meaning that no two games are alike. Each class has a unique style of play, so trying a new one can be exciting.
Play as a different class – this one might be obvious, but players should try a different class in a new playthrough.
