Main Cannon, Make Ready… Fire! Event Guide

Sail your Waverider and clear out every monster encampments you can find. When you finally found hilichurl encampments, you can attack them with Waverider armament or just defeat them directly with your character.

I found some guide from Paimon in hoyolab forum, here’s the details:

Waverider Armaments

Main Cannon, Make Ready... Fire 2 Kind Of Monsters Tower
2 Kind Of Monsters Tower

The Waverider is equipped with two types of armaments — the Swiftstrike Cannon that shoots Swiftstrike Cannon and Heavy Cannon. The Waverider’s two armaments are capable of dealing considerable damage to light floating towers, but cannot damage heavy floating towers.

Attack The Enemy With Your Waverider
Attack The Enemy With Your Waverider

You can use the Waverider to destroy light floating towers and defeat enemies by sending them plummeting into the sea.

Destroy Enemy Wind Barrier

You can also climbing to platform directly and defeat the enemy. As for tips, use charged attack to throw enemies to water. If the enemy is in another platform, use archer charged attack to knock them back and throw the enemy to water.

Some enemy encampments may be shielded by a Violent Wind Barrier. Travelers will need to use the Heavy Cannon or Explosive Barrels to destroy it.

Collect pity pearls to greatly decrease the cooldown of your Heavy Cannon and bring the barriers down faster.

Beware of Whirpool!

There may be Whirlpools near the sea monster encampments. Please avoid the Whirlpools during the challenge.

If caught by the Whirlpool, the Waverider will start taking continuous damage and Travelers’ Stamina will be rapidly consumed. If the Waverider is destroyed, Travelers will automatically be ejected from the Waverider.
