Just some random things I thought about that would be cool to have in game.
-Clockwork key
Reward for Cradle and all achievement or maybe a Event item to celebrate some occasion like there 4th anniversary , it is a Back accessory that would have a winding animation and looks like this ----> http://www.shutterstock.com/pic-5259901/stock-photo-conceptual-clockwork...
And lucky us, we even already have a Key model to work with (But maybe it should be recolored Silver or Gold) http://wiki.spiralknights.com/Heavy_Deconstructor
-Bunny ears
What? it's getting close to easter -3-
Would work just like Vertical vents but rounder and taller! Im guessing Divine would be most popular... or it could be a event item, to gather Easter eggs (like tokens to win it)
-Party aura
Would be a aura with the raining confetti effect!
That's all I got for now If I think of anything else I'll edit it, let me know what you guys think!
key gates are the same as clockwork keys
