Flash Powder Factory

The Flash Powder Factory is a minigame that replaced the Rogues' Den. It was released on the 13 December 2011.

After the Imperial Guard took notice of the old Rogues' Den, Brian O'Richard shut down his maze and opened the doors to his Flash Powder Factory instead. Inside players can operate the factory, while dodging obstacles and the sneaky fingers of other players.

Agility, Thieving and Herblore experience can be gained from the Factory, and pieces of the old Rogues' Den rewards can also be found lying around.

All games at the factory take place on an instanced shard world - accessible from any server but actually taking place on another server.

Location
The Flash Powder Factory can be found inside the Rogues' Den, which is below the Toad and Chicken bar in Burthorpe.

Requirements

 * 75
 * 75
 * 50
 * Stat boosting items CANNOT be used to gain access to the factory.

Playing the game
The aim of the game is to make flash powder. The first step is to collect the two reagents known simply as "A" and "B". These can be obtained from the reagent machines A and B, marked with blue and orange arrows on the minimap, respectively. These can also be located by checking the map where the world map icon usually appears.

To navigate the map, players must pass agility obstacles that separate each room. Some rooms also have 'pressure doors' between them, which can be blocked off, making navigation more difficult. Doors will lock or unlock when catalyst is taken from a machine in a room that it is joined to. Some doors may be opened by operating the nearby call buttons when they are blue - if the button is red it cannot yet be opened. If a player is trapped in a corridor by two locked doors, they have a few seconds to step through one of the doors before they get teleported out, ending the game early.

Once both the reagents have been obtained, they must be taken with catalytic powder to one of the four mixer machines, marked by the dark red arrows on the map, to make the flash powder and gain points. Players start with 6 catalytic powder, although more can be collected from the catalyst machine in the centre of the arena.

You will gain a minimum of 100 points for each flash powder made. Additional points can be obtained when making powder by having a bonus, provided by certain factors: Note that the bonus stacks additively - the individual bonuses will be added together to form the actual bonus.
 * Charge - charge can be obtained through an active charge machine, marked with an electricity bolt on the map. The machine will give a 10% bonus for 100 seconds. As a result of two active machines the maximum bonus is 20%.
 * Apparatus - determined by the number of refining apparatus in the inventory, a maximum of 6 can be held at one time for 15% bonus when making flash powder. Players will have three of these at the start of the game; more may be obtained by pickpocketing other players in the arena, but they may also be lost to other players who are pickpocketing. The number of apparatuses each player has will be displayed as a number of green bars above their head. It is not possible to pickpocket a player immediately after they have pickpocketed you, nor can you pickpocket one twice in a row. There is a slight delay in the ability to pickpocket if an attempt to do so fails. It is advised to click quickly to either escape pickpocketing or to pickpocket the other player before they can pickpocket you. There is no period of immunity in the beginning of a game, so players can pickpocket or be pickpocketed immediately after spawning in the factory. Since pickpocketing only gives a bonus, it is generally better to focus more on getting to the correct machines.
 * Residue - increases by 1% for every flash powder made.
 * Factory outfit - Wearing the full set gives an extra 10% bonus if the bonus by the above means is equivalent to a score of 120 or more when making the flash powder.

While traversing through obstacles you may come across Fallen Rubble. Searching these may yield pieces of Rogue armour, flash powder, catalytic powder or sets of apparatus. It is also possible to find nothing at all. It is assumed receiving a piece of Rogue Armour is considerably rare.

Rewards
Within the factory, the player will earn points referred to as Brianpoints. They are determined from your score by counting score before 500 as .2 reward each, and points after as .05 reward each. The total score is rounded down. So, for example, 615 score turns into 500*.2+115*.05=105.75, rounded down to 105. This means, for maximal efficiency, you should leave before your score reaches 500.

The amount of time spent inside of the factory seems to award a small amount of points. This initially caused people to think 625 was the score dropoff, but it was actually time awarded points being added on at the end that gave this illusion.

These points can be used to buy rewards from Brian O'Richard. The rewards that can be bought are as follows.


 * Agility and Thieving experience.
 * Factory outfit.
 * Factory mask - 2250 points - increses the chance of finding items in fallen rubble.
 * Factory body - 3500 points - gives an extra 2 minutes in the game.
 * Factory legs - 2750 points - gives an extra 3 Catalytic powder on entering the game.
 * Factory gloves - 1750 points - increase the chance of successfully pickpocketing by 10%.
 * Factory boots - 1750 points - reduce the failure rate on obstacles.
 * Multitool - 35 points
 * Wearing 3 out of the 5 Factory set pieces allows you to make 4 dose potions instead of 3 sometimes.
 * Wearing the full Factory set gives experience for making unfinished potions, equal to the amount of cleaning the herb used.

Trivia

 * On the day of release players received the message "The instance you tried to join is full. Please try back later." This was due to a bug limiting the number of instances and the huge volume of players trying to access the minigame. Players on foreign servers did not have this problem.
 * Brian O'Richard opened this factory, here is a quote of what he said: "Depressed. My wonderful Rogues’ Den is full of cooks rather than thieves, using the everlasting fire to burn lobsters. It is hardly the purpose I had in mind for my wonderous cavern." (From Runescape "Behind the Scenes December" News)
 * If you switch your language on the main RuneScape page to something other than english, you will go to a shard world used only by the worlds of that language, meaning if you go to Brazils page, only 2 members worlds will feed into the shard world you'll be put in to play the game.
