The Accretian launcher is an enormous ranged weapon the size and power of which make it unusable by any other race. Launchers can fire missiles across great distances and are capable of firing many different types of rockets with either physical or elemental damage properties. However, there is a great delay period between shots but this delay can be overcome by using launcher specific armour. Accretians have the additional ability to enter siege mode, increasing fire rate but disallowing motion. Launchers can only be used at levels 15 and above and Siege Kits can only be used at levels 30 and above. There are currently two different Siege Kits: the level 30 kit is good for 1000 shots and increases defence by 20%, the level 40 kit is good for 1500 shots and increases attack power by 35%. After a Siege Kit runs out of durability it is destroyed and the player has to buy a new one.

The game's economy can be divided into two parts - production and consumption. Most other MMORPG economies focus on hunting. The mine is a new field where resources are produced as a part of and in support of economic activity. Mining for minerals and processing the products of these produce many kinds of items. These form the basis for conflict within the mines.
Also, just like in the real world, overproduction causes prices to fall. If many players convert their ore into currency, the going price of ore will drop as supply begins to outstrip demand. Every hour, the economy is recomputed taking into account sales of items over the entire server and who currently controls the mines. This system places the economy (mostly) in the hands of the players.
Every twenty-four hours, the amount of currency in the economy is re-calculated, and based on this, a tax rate (inflation rate) is established for each race. The tax rate makes NPC vendor items more expensive. Players can keep the tax rate in check by converting their currency into gold. The cost of gold is based on the tax rate; Higher tax rates mean cheaper gold, while lower tax rates make gold more expensive. In this manner, the tax rate prompts players to convert currency to or from gold based on whether or not the economy suffers from inflation or deflation.

Certain battle dungeon keys also yield money when the objective is met. Before Ep2, these keys are dropped by monsters or can be bought from Sundries Vendors in HQ. as of Ep2, the sundries version is gone. "BD farming", as it has been coined, is a simple way of gaining currency through an easy method.
Since the Episode 2 update, ore has no value when sold to vendors. In order to profit, it has to be purchased by other players on the Auction House. The ore may be processed, but the materials when sold off to vendors usually does not meet the cost of processing the ore. Other items such as gems or talics can be sold in the Auction House (AH) for increased profits.
