This Dendro Reactive Team team focuses on Magishroom's Dendro attacks and Bongo-Head's and Stormsage's Hydro and Electro, to constantly trigger Hyperbloom, and Quicken/Spread. Both reactions are high in damage, plus the Li'l Fungi needed for this can provide heals/utility to the team.

You can also trigger Burning/Burgeon using the nearest Mystic Blaze, but since its coverage is limited and is immobile, you can only apply such reaction on the first Thundering March and the second Windblade

The fourth member of this team is entirely up to you; depending on how your style for this stage is going to be. A safer, more well-rounded option is to bring Twirly-Whirly to trigger Swirl without removing Electro/Hydro aura, or Rocksteady, for the shields.

How to Defeat Thundering Devices

Prioritize Mechanici by Level of Threat

Genshin Impact - Fungus Mechanicus Day 4 Guide for Thundering Devices - How to Beat - Prioritize Mechanici by Level of Threat
Use the Mystic Blaze to immediately trigger Burning/Burgeon on the first Thundering March, then immediately go for the first Windblade on the left side of the board, afterwards. Take note that Thunderflash is the biggest threat among the normal Mechanici in this stage, so it's important to go after them first.

As for the enhanced ones, we suggest taking down Water Mirror first because of its pesky Hydro shields!

Do not Defeat the Second Windblade

Genshin Impact - Fungus Mechanicus Day 4 Guide for Thundering Devices - How to Beat - Do not Defeat the Second Windblade
Windblades are mechanici that spawn on the more outlying side of the board. First one spawns on the left side, while the second one is just across it, on the right side.

For the second Windblade, we suggest holding-off the attacks against it, until you've defeated the Thunderflash that spawns on the upper-left side after the first Windblade goes out.

Targeting the second Windblade otherwise, takes your Fungi away from the center, where most of the incoming Mechanici will spawn, therefore losing valuable time in defeating the enemies within 240 seconds!

Do Not Spam Your Abilities

Genshin Impact - Fungus Mechanicus Day 4 Guide for Thundering Devices - How to Beat - Do Not Spam Your Abilities
Spamming your abilities in Thundering Devices can be normal at first, especially with the high-damage output of the Mechanici in this stage. However, we strongly recommend saving your abilities only when you needed, especially your Heals/Shields!

The most viable situation in using your Heals/Shields is when an Enhanced Mechanicus is around, most specifically, Thundering March. Prematurely using your abilities without any of the enchanced mechanicus present, could mean losing some of your Fungi, and by extension, losing the stage.
