Spiral Knights is an awesome game!
Everybody that plays it knows that its totally awesome and fun to play. Its a great tribute to Zelda and Bomberman.

Going down the dungeons and fighting monsters, uses up all your Mist energy and Crystal energy!(CE) and the only option you have left is chat with co-players, go to Auction House, go to Advance Training hall and mess about or buy more Crystal Energy for more game play.

If your like me who doesn't want to waste money buying more CE or Who gets bored when you run out of Mist or Ce.
I think that a "Player Vs Player" in the Training Hall to pass the time is a great way to do it. I as a Spiral Knight Player know for a fact that everyone that goes to the training hall just mess about and i think that kinda cool. Its a place where you can show off your cool weapons in action.

Therefore by introducing an area in the training hall where Knight has a free for all combat with one another, will not only make it funner but will also improve players game play as they will try to dodge attack and will also think ways how they can defeat the opponent, or team up to defeat a certain player. But the thing about this is that you can only battle one another in the enclosed arena(it should be big for more players to fit) so once you leave this arena you cannot inflict any damage to other players!!!

How it will all works!

-You should prove Vitapod outside the arena which enable Knights to have more health for combat
-Around the arena should be filled health and vials.
-On hit is one damage
-When player dies they can revive themselves just like when you die in the Training hall
-Anyone should be allowed in the arena and knights can attack anyone.
-The Higher the weapon is i.e. 5 star weapon. The more damage it could inflict to the opponent.

This is my idea!(Some people my have though about this too but this is just my version of it!!! )
Thanks for Reading!!!!!!!!!!!
