Tutorial
In Fire Support Assault, you need to defeat as many enemies as possible within the time limit to earn a battle rating. After the challenge ends, rewards will be granted based on your battle rating.
Each battlefield has a unique feature that favors specific combat styles.
During battles, defeat enemies to accumulate Support Progress. When Support Progress reaches its maximum value, you can enter Guidance Mode to designate targets for the Guizhong Ballista's long-range strikes, eliminating enemies on a large scale.

After entering Guidance Mode, you need to actively aim at the targets to ensure that the long-range barrage hits the enemy accurately. High-speed, general-purpose ammunition will arrive first. After a period of time, explosive ammunition will arrive, increasing the attack range and DMG significantly.
Additionally, defeating enemies in Guidance Mode greatly boosts the battle rating obtained.

Like the Unshakable Mountain

According to modern military doctrine in Teyvat, the deployment of forces should resemble a crashing thunderclap instead of a rolling rumble.
