Seeing a few threads about this topic: PETS. Only read one and it suggested having the Snipes that go fly about Haven as pets. Though it also suggested being able to train one to help in battle. My suggestion is simple. Regular Companion Pets to accompany you into the danger ridden depths of the Clockworks. They could have Vendor in the Bazaar that sells Snipes of different varieties (black, white, yellow, undead, volcanic, or get the idea) for crowns but also pets based off of the monsters you face during your expeditions into the Clockworks for the tokens you get. Here would be a list of some possible pets (and their possible antics) sorted by the tokens that you'd need to trade for them.
Forge Spark:
Mecha-Squire (follows you around and occasionally takes practice swings with it's sword that leads to it stumbling/ tripping)
Shoulder-Mounted Gun Puppy (occasionally fires a nerf dart/pellet in a random direction)
Gremlin Orphan (tinkers with a random gadget)
Grim Spark:
Devilite Intern (takes notes)
Greaver Pup (occasionally lands on you hand to rest)
Shoulder-Mounted Howlitzer (occasionally bites at the air)
SpooKitten (mews, ya i know but i can't really think of things that a real kitten can do that a ghost kitten can also do)
Floating Phantom Skull (floats around hauntingly)
Primal Spark:
Baby Chromalisk (hangs out on your shoulder and occasionally grabs a bug with it's tongue)
Wolver Pup (sits up and barks, occasionally rolls around and chases tail)
gentlecube (jelly cube with a monocle) *not to be confused with the impostocube who has hair, mustache and pipe
Boss Tokens: (bought with tokens obtained from the bosses their based on. Only knights with the artifacts obtained after the boss can purchase boss pets depending on what artifacts they have. i.e. knights must have Recon Module: Gloaming Wildwoods to be able to purchase baby Snarby and Echo Stone: Gloaming Wildwoods to be able to purchase Rabid baby Snarby.)
Baby Snarby (stands up and let's out a cute roar)
Rabid baby Snarby (same as baby Snarby but foams at mouth)
Almirian Shade (floats around and occasionally sobs for his lost kingdom)
Roarmulus Prototype (shoulder mounted, fires nerf darts and shoots out a nerf dart in a mortar like fashion)
Red Roarmulus Prototype (same as Roarmulus Prototype)
Heir Jelly (occasionally spins about)
Icy Usurper (spins and also shivers)
Just wanted to put my ideas somewhere and maybe get some input about them.
Those that are shoulder-mounted/fly around you, can become accesories or auras.
