What about a new mode for our knights to play in?

Arena Mode
- Its a Onslaught Mode that lets go through multiple waves of enemies and along the way you earn crowns for each wave defeated, but to participate in the Arena Mode or Onslaught Mode you must get a Ticket for entrance that could be acquired by a new NPC. I thought of maybe that the Tickets would only cost 100ce. The crowns you earn for each defeated wave is increased per wave, so does the difficulty of surviving it. This way it will be easier to produce crowns and also time consuming. The cap of waves you can defeat is about wave 20 which is the most difficult wave, also it will have the highest prize pool of 10,000cr to make you really wanna finish it. And finally the Rules of this Mode.

Rules (This rules will be extreme due to the huge amount of crowns on the line)
-You must Enter ALONE.
-You can NOT die or else you lose the match and go home with a 50% decrease on the prize you've earned.
-You may not quit a Onslaught Match once you have started.
-You can not heal as well during a wave, only when you have defeated a wave will you be back in full strength.

Since this gives such a large amount of crowns per run (although if you die in the middle you get shut downed 50%), I believe that the difficulty of the waves should go to an extreme point just by reaching wave 5 since I the prize pool would increase 500cr per run like this.

Wave 1 - 500cr
Wave 2 - 1,000cr
Wave 3 - 1,500cr
Wave 4 - 2,000cr
Wave 5 - 2,500cr
And So on and so forth.

So if you die in Wave 5 for example you will get 2,500cr as a profit for the 4 waves you cleared.
If your asking why its not 5,000cr its because you were affected by the 50% decrease when you die.

The Difficulties

I think the difficulty for this Mode should be a lot harder than anything this game could offer. Like a Huge HP Lumber/Trojan, Huge swarms of slimes, Multiple Gun Puppies or Polyps, these should be put in to the field when you've reach Wave 10 since Wave 5-9 is just like going to a JK run with 4 members fighting alone (can get the difficulty of that can't you?). So my best bet is to pump up the difficulty to balance out how worth it is it to use 100 energy for 1 run of this Arena Mode.

Your Suggestions

Party Groups
- Yes its a good suggestion, but if we would apply this we would have to eliminate reviving options to balance the difficulty to the amount of the prize pool.

Number Tweaking
- I don't really think it would need tweaking and the price for the ticket is just 100ce meaning you can do it everyday using your mist, and the Prize pool is not really a bad thing that its over priced because the Arena itself is INSANELY HARD. So what I'm saying is that this mode is up to the very pros of this game those who know how to use the skills of survival for this game so not all can finish this because its like Soloing Vana without taking even 1 damage from anything. So you see its kinda balance it out and if you read the upper part "When you die you lose 50% of the profit". But I guess slashing it down to 5,000cr in Wave 20 might be good as well, and probably lowering down the difficulty as bit. So it would start to 250cr and increase with 250cr per wave.

Quitting
- I guess we could apply this as well but the 50% decrease in the profit MUST take effect so if you quit on Wave 5 you still get 2,500cr and not 5,000cr like I said earlier.

KC Combination
-It really would probably be related to it since its a Arena type thing....

Maps
-The Maps I thought of was just like the arenas in the Clockworks. Small, Trappy and Full of Dangerous Surprises (Knight hate Dangerous Surprises) so I wouldn't like it if the map is as big as Lockdown that would be time consuming.
