Not so long ago (unless you are reading this about a month after i posted it)accessories were released in Spiral Knights. I thought that was a great idea, so now everybody is unique in a way and you won't have a bunch of people in Wolver coats standing everywhere, not knowing who is who. The Silver Lockbox already made accessories hard enough to obtain, but the silver key just ruined it all. I mean seriously first you spend all you mist energy or crowns in the Clockworks or doing Lockdown and now you have to put up with this? 750ce is quite something (in ce)think about all the items you could craft or how many times you could go to the Clockworks. Accessories don't actually do anything than make you look good. My point is that the cost for Silver Keys should be decreased OR they remove accessories from the game completely.
Silver Key Of Leeching
I find it pretty expensive, too, but then again it appears to me, many people spend their CE on it, because theres so much stuff on auction for less than 45000 crowns. However, if i wouldn't need ~1000 CE for making my Blizzbrand into a Glacius, I would have 750 CE too much at the moment. So if you desire a rare accessory that's not available in AH (e.g. a Volcanic Halo) that's totallly the reason for opening lots of lockboxes and spending tons of CE on silver keys.
What I mean is: They shouldn't be removed from the game, because nobody is forced to buy them. It would be nice, if they were cheaper though, because opening a lockbox can lead to a big loss, because the contents often have a value far below 750 CE. Just sayan.
accessories are just made for people who own LOTS of CE (or money), that's kinda stupid, i agree with you.
there should be a way that everyone can get some accesory rather than spending 750 CE for a silly silver key.
even if you get enough CE for a silver key the chances you have to get a good item is like 1/10.
You answered yourslef with "Accessories don't actually do anything than make you look good" so who cares if they are expensive, some players like to pay for them, let them be. It won't afect your gaming experience.
