Siege engines

Catapults, ballistae, trebuchets, rams and siege towers: how to get one, crew it, and pack it away.

Getting one

  1. A city's Siege Workshop (needs a rank-3 Heartwood) builds engine kits from planks and iron. The Inner Council picks which kit on the City tab.
  2. Kits go into the city's material storage. An Inner Council member takes one out.
  3. Without a city, buy a kit from the Siege Engineer at a capital's inn. It costs more than the planks and iron a workshop spends.
  4. Double-click the kit in your bags. The engine assembles on open ground in front of you. With no room, you keep the kit.

Operating it

F
Take the controls (anyone may, one at a time). Press again to step away.
W A S D
Drive it (catapult, ram and siege tower). The ballista and trebuchet stay put and only turn.
Mouse
Aim. A ballista points where you look. A catapult or trebuchet winds its arm: range follows the elevation, not a sight line.
Left Mouse
Load, then fire. A ram strikes 5 m ahead of itself.

Siege tower: raise or lower the bridge.

City walls are built to last: a lone trebuchet needs many minutes to bring down a wall section, and a ram opens a gate in a couple of minutes. Bring several engines, and guard them.

The siege tower

Drive it against a wall, lower the bridge with 1, and your side climbs the ladder at its back onto the deck and across. See Climbing ladders.

Packing it up

Select an engine and press H to pack it back into its kit: a 60-second channel. The engine must be at full health, with nobody at its controls, on its deck or on its ladder, and you within about 6 m. Moving or taking damage breaks the channel; press the key again to cancel.
