To begin the Operation Downpour Simulation event, you will first need to complete the short quest titled "Operation Downpour Simulation," which will give you an idea about the wargame. This event has a total of 11 challenges, with the first four challenges unlocked on day one and the rest unlocking on subsequent days.

As stated, the Operation Downpour Simulation event works like a tabletop wargame, wherein you will need to select and deploy units for both offense and defense. All units are divided into either melee, ranged combat stance, and they will act accordingly on the battlefield.

Melee units prefer charging head-on and will destroy any obstacles in their way to get to the enemy targets. Ranged units can only fire from a certain distance, and will not move from their positions till the enemy unit they are attacking is defeated. You are allowed to have a total of five units on the field at once.

Challenge #1: Frontline Formation

This challenge features Cryo Whopperflowers as enemy targets, while your lineup consists of Hilichurl Fighters (melee units) and Electro Samachurls (ranged units).

This challenge is pretty easy, as all you have to do is deploy two sets of Hilichurl Fighters and Electro Samachurls on both the left and right sides of the battlefield. They will easily take down the enemy Cryo Whopperflowers without any further input from your side.

Challenge #2: Thrust and Volley Combined

The enemy lineup for this challenge features two large Hydro Slimes and two Treasure Hoarder Pyro Potioneers. Your lineup will consist of two Ruin Guards (melee) and two Hilichurl Grenadiers (ranged).

This challenge is also easy, as the Ruin Guards are tanky units who can take a lot of damage. Deploy all four of your units one by one on the bottom of the field, and let the Ruin Guards break through the blockades, following which all your units will focus on taking down the Hydro Slimes and the Treasure Hoarder Pyro Potioneers one by one.

Once the Whopperflower is defeated, deploy two groups of Hilichurl Fighters. Finally, deploy the last group of the Electro Cicins. All the units on the field will now work together to defeat the rest of the enemies and structures.

This challenge includes enemy units such as the Suppression Specialist Mek: Ousia, Large Hydro Slimes, as well as a Shackling Mine mechanism. Your units will comprise of Cryo Specters (ranged), and Hilichurl Fighters (melee).

Once they have defeated the two Hydro Slimes, deploy all your Hilichurl Fighters on the left side of the field, near the opening by the palisades. While a couple of them will get stuck in the Shackling Mines, the rest will charge ahead and defeat the Suppression Specialist Meks.

Start by deploying two groups of your Hilichurl Grenadiers on the bottom right of the battlefield.They will immediately target the Treasure Hoarder Pyro Potioneers. Once they have defeated them, deploy two of the Hydro Mimic Finches in the same location.

After these Hilichurl Fighters and Eroding Avatar of Lava have moved further in and drawn the attention of the Suppression Specialist Mek, deploy one Cryo Specter on the left side of the field.

Once you are done, you can run a defense simulation, which will give you an idea of how your formation will hold up against an actual attack by the opponent. After you are satisfied, you can go ahead and match with real players in order to play the PvP challenges.
