Aim for formations
Choose a target whose size and position make an area bombardment useful. Dense infantry presents a different opportunity from a lone fast-moving character. Retarget as the fight changes instead of leaving the battery shooting at a poor target throughout the battle.
Place the artillery where it has a workable shot and room for supporting troops. Enemy cavalry and flyers can cross the battlefield to reach it, so keep a reserve or a protected approach between the crew and those threats.
Watch the close fight
Explosive artillery becomes harder to use safely once friendly and enemy troops are intermingled. Check where the rockets will land, change targets when necessary and stop firing if the shot creates more danger for your own formation.
The battery is a war machine with a crew rather than a line-holding infantry unit. Moving it late in a battle can take time; plan the initial position around both useful targets and a route away from pressure.
Recruiting the battery
The Fire Rain Rocket Battery belongs to Grand Cathay's regular roster and is supplied through its gunpowder and artillery military chain. Use the building browser to locate the battery's unlock and develop a province able to recruit it.
Jade Warriors can hold approaching infantry while other units watch the flanks. Miao Ying or Zhao Ming can help contest a dangerous part of the battlefield, but the lord's presence is most useful when the rest of the army can continue doing its jobs.
Recruiting across Cathayan factions
Miao Ying, Zhao Ming and Yuan Bo use Cathay's regular roster alongside their faction mechanics. Bhashiva develops access to Cathayan forces through Iron Favour and modified military buildings. Check the recruitment entry for the faction you are playing before planning a replacement army.
Use the unit's battlefield role to decide what support to add. A spellcaster supplies magic, while Saytang supplies a separate heavy ranged presence; neither fills every job required to protect an artillery position.
