Siege Weapons are large scale weaponry used on the battlefield.
Siege weapons must be built on Siege Pads found in the world or on Keeps. They cannot be deployed anywhere else and the number of siege weapons used is limited by the number of pads. Furthermore, siege weapons cannot be moved once placed, although they can be rotated.
Siege weapons do not require a Trade-skill to build and can be deployed by anyone. They are purchased from War Camps or from an NPC inside the keeps. Once purchased, a siege weapon will take up a single inventory space. These items have no weight, and can be carried and traded by anyone. Players can carry as many siege weapons as they want, as long as they have space in their inventory. When a player deploys a siege weapon, the item will disappear from the player's inventory.
Siege weapons will increase in cost and power based on location/Tier purchased. (The exact cost of siege weaponry has yet to be determined.) A Siege weapon purchased in a higher Tier cannot be placed on a lower tier Siege Pad. Only one Siege Weapon can be on a pad at a time. Siege Weapons have a life span of 30 minutes and can be destroyed by the enemy before that time.
Rams are can be used against keep doors or other pre-selected targets
Ballistae can be used against individual players or other siege weapons
Cannons, Catapults and Trebuchets can be aimed to fire at a selected location, doing splash damage to players or other siege weapons
Boiling Oil can be used to rain down liquid death from keeps and walls
Siege Pads are pre-set locations on which Siege Weapons can be deployed. They are physically represented in the world as large slabs of concrete, slate, or otherwise engraved pads.
Keeps will have one Siege Pad per destructible door for placing Rams (for the attackers) and several pads for Ballista, Cannons/Trebuchets, and Boiling Oil on the Bastions (for the defenders). The surrounding area of a keep will have 4-8 locations on the frontal arc of keep for Ballista or Cannons/Trebuchets, and 1-3 locations per side arc of a keep.
To place a siege weapon on a Siege Pad, players simply right click on the pad to open an interface window. This window will display the siege weapons available to the player to be placed on the pad. Only one person can interact with the Siege Pad at a time.
Players have the ability to destroy and repair Siege Pads to add another level of strategy and depth to the siege mechanic. Siege Pads can only be destroyed by Ballista, Cannon/Trebuchet fire, or special demolition charges purchased from War Camps or keeps. A destroyed Siege Pad cannot be used to deploy siege weapons as the ground is littered with wood planks and metal bits. Siege Pads have very few hit points but repair themselves after several minutes.
Siege weapons are under the control of the player that built them and only one player can operate them at a time (except for rams). However, control can be relinquished leaving them open for another player to assume control.
A very simple UI element will be used for Siege Weapons utilizing a three click "golf swing" meter. The more accurate your clicks on the meter, the more accurate your shots will be.
