Make a Coin Gun- shoot your crowns at enemies! Charge attack throws big gold coin

challenge elevator/room
no mats or Cr drop, cost a few hundred crown-1k crown to enter
specific challenges give you a certain costume recipe(bound/auto-learnt) to show youve beaten that challenge(maybe crafting that costume is as above, no ce + a ton of mats)can only craft the 1 costume which cant be unbound.
scoreboard for most kills, longest survived, avg DPS, highest hit in solo or party mode
can choose your enemy theme or combined theme(all have their own scoreboards) by adding crystals or by just clicking the option of which theme.

doubt anything like it would be added, just always like the idea of a survival room, waves and waves until death.

I've suggested this before.

Craftable mist tank:
On use: adds 50 ME.

Cost:
50 CE + 1000 cr + mats (preferably ones that currently see little use)

Note that this does not allow you to make energy (since it costs as much as it gives), but it does allow a player to save ME that he/she doesn't use for "a rainy day", at the cost of crowns and mats.

To prevent abuse these tanks should not be tradeable, and probably should expire after some time (say two weeks) to prevent hoarding.

i like the costume and coin gun ideas

-ther was that armor gear in twilight princess, that reduced money instead of health, maybe could connect/embed(as in fill gear with crowns) all kinda gear with crowns to add more functions to it(e.g power-up as in more dmg/def/hp/w.e, special move, extra combo, awesome sauce looks/colors/special graphics, etc..coin gun would be either a special move or a unique weapon then)

as a side effect, knights with gear, that is filled with too many crowns, could be having speed penalties
unbinding could remove all crowns just like with heat

i know its a silly idea, since such a feature would make more sense with energy, but meh, krogmo gets bribed with energy instead of crowns too >.>

The use is in converting ME to a tank, that can be used at a later moment. This is mostly useful for players that do not have time to play everyday, but might want to play some extra on the weekend or something.

Personal color changers NPC. Offers all the basic colors you can choose from at knight creation for a price. Offers some premium colors (ex: white and black) that are not available at creation at a higher price.

Armor/weapon dying NPC. Should be fairly obvious but dyes some of the armor/weapon another color. Could offer 2 different parts to dye for most armors, the main armor and the accent for it (ex: Vog and the glowing magma accent on the ears of the cap). Weapons could be done the same way but some parts would have to stay the same color for PvP reasons... most notable is the Brandish 5* center color and the status bombs. Again basic colors are lower priced then the premium colors.

Guild Hall upgrades. Add either a NPC or a machine that sells permanent upgrades to a guild hall. 50k minimum for the upgrades. It can be almost anything you want but some ideas are: the various NPC vendors, a Krogmo Coin Alchemy Machine, a dye and personal color vendor like I mentioned above, etc.

This one I don't think I'd personally use much but I know a lot of people would. Create houses for the knights that are connected via the trade chat and their own local chat. Getting a house costs crowns and the size could be upgraded with more crowns. After that you can craft/buy furniture items for it. Could have another basic NPC furniture recipe merchant in Haven and Basil's gf could sell the furniture recipes at the same depths Basil does (name her Ginger just for giggles). Could create unique furniture that is tied to boss tokens that bind upon receiving. As for the crafting, just straight creation... not the 2* becomes 3* becomes 4* like for equipment.

Other then the actual crafting of the furniture items all the above should use just crowns.

I think the most obvious thing to do is change the CE cost for slot upgrades to crowns. But it won't happen, OOO is running a business, the business is selling CE for people to use.

All the uses of CE in haven could be converted to crowns without OOO losing any CE sales. The important thing to realize is that the only way crowns (or materials) get fountained into the game is by running gates, and running gates *always* uses energy. So, say that currently 50% of all gates are run with mist, the other 50% is with CE. Then, if you changed all CE prices in haven to be about 13000cr per 100CE, players would end up having to sink enough crowns to equal the same amount of energy OOO currently get. Of course, OOO would need to see just how much CE gets sunk per crown fountained, it probably isn't 50% and they would also need to take into account that such a large increase in sunk crowns would cause the exchange rate to drop. My guess is that OOO would only need to use about an conversion factor of 7.5kcr to 10kcr to end up sinking the same amount of CE.

People would have to play more to get the things they want, but they would be able to buy CE with crowns much easier. This could also change the mindset of CE buyers to be closer to OOO's other game (puzzle pirates) were people often buy CE (doubloons) primarily to get crowns (PoE), rather than as a side effect.
