i suggest pets in the game.
pets are great for occupying time while waiting for mist energy.
most games have pets why shouldnt spiral knights?
pets dont have to be cuddly puppies or kittens they can be pet dragons and robots.
pets can help you in dungeons from picking up items for you and fighting inflicting that amount of damage needed just to wipe out a boss.
and you would have to take good care of your pet or they will die or stuff like that.
pets would be help full in may ways.
