This would be a new dungeon, accessible via the Town Square.

Immediately on entering, a knight named Forsence Greets you. The room would be like the interior of an arcade, except with a lot of the computers everywhere and a single elevator down. He will explain how it works.

Well met noble knight, you stand before the pride of Spiral HQ scientists. I'm Forsence, head of the Spiral HQ Research and Development Division.

This is the Simulation Dungeon. Here we have collected data from all the journeys into the clockworks. With the BSD we salvaged from the Skylark and the unique power of the minerals, we are able to create a simulation for knights to experience.
> BSD? (Advancing the conversation)
> Details, who needs 'em, bring it on! (The goodbye option)

The Battle Simulation Driver. It lets us create fairly realistic images of enemies you have encountered before. If you give us the minerals, we can create a safe dungeon in which you can practice your skills.
> Sounds cool, how does it work? (Advancing the conversation)
> Good enough, thanks for the sitrep. (The goodbye option)

First you must go through the Clockworks, experience many gates. Afterwards, we log your progress and we can access any single level you go through. With it, we have the exact proportions of minerals required to generate a BSD for that level. We also have developed a support floor where we can generate extra equipment for use inside the Simulation Deck. You will find Vitapods relevant the the Tier and various potions or capsules. Once you and your party are ready, descend down and our engineers will create the battle. Keep in mind however, you cannot gain anything from simulation dungeons. Instead, you will collect Score Orbs that will judge your performance.
> Thanks, I'll get going now. (End conversation)

The Gate is named Dreaming Hawk. It has two floors. It will not cost energy to start or advance deeper. It will however, cost 10 minerals depending on the type you want. It will use the ratios used in Gate Creation. For bosses, it will also use the ratios for that type of floor. The gate select would be something like:

============Stratum: Jelly==============
============Levels Available============
Lichenous Lair: Prognosis: Symbiosis
Lichenous Lair: Fiery Fusion
Lichenous Lair: Cold Fusion
Lichenous Lair: Shocking Synthesis
Lichenous Lair: Toxic Union
Aurora Isles: The Jelly Farm
Aurora Isles: The Jelly Farm II
Royal Jelly Palace: Garden of Goo
Royal Jelly Palace: Red Carpet Runaround
Royal Jelly Palace: Battle Royale

Once you select which level you want and input the minerals, you can enter the dungeon. You enter a room that has a Knight next to a very large computer with a dumping chute hooked up. You can talk to him (Supply Sergeant Gears) and he opens up a shop menu. Here you can also invite party members, who do not have to pay anything.

Everything in the shop will cost 10 crowns. You can buy any belt item or vitapod relevant to the tier you chose. After you finish setting up, head down the elevator and enter the dungeon you specified.

Crowns and heat are replaced with score orbs. Score Orbs are given to everyone, and take up the heat spot.
Reviving will affect your party's end score. It will not cost energy to revive, but if you choose to revive, it will deduct a percentage from your total score at the end. Getting revived by an ally will not have any penalties.

At the end of the dungeon, you will be given a score:

Score Orbs = #

Multipliers

Monsters Killed = #% ( # / # )
The percentage of monsters defeated will become a multiplier. Respawning monsters does not go toward the total.
25% or less will yield a no boost.
26% - 50% will yield a boost of 10%.
51% - 75% will yield a boost of 30%.
76% - 100% will yield a boost of 50%.

Casualties = #
Each time you pay to revive, you will deduct 5% from the total. This will stack up over time. 5 revives = 25% loss.

Party Size = #
Bigger parties are given bonuses.
Solo = 10% boost.
Duo = 20% boost.
Trio = 30% boost.
Full Party = 40% boost.

Time Taken = #
The average time for the dungeon will be judged by the GMs.
Blitz Time (25% or lower of the Average time) = 50% Boost.
Fast Time (75% or lower of the Average time) = 10% Boost.
Average Time (The time the GMs took, give or take 25%) = 0%.
Slow Time (125% or more of the Average time) = 10% Reduction.
So Zetta Slow Time ( 175% or more of the Average time) 30% Reduction.

Total = #
It will apply the entire multiplier at the same time to your original Score orb count.

Example:

Royal Jelly Palace: Battle Royale
Score Orbs: 5000
100% (1/1) Monsters killed: +50%
2 Casualties: -10%
3 Man Party: +30%
Time Taken : +10%

Total: 9000

You can use this score to compete with friends.

The entire point of this idea is:
A) An energy free dungeon for practice
B) A high score people can compete with (prizes maybe?)
C) Fun

Whaddya think?
