How to Beat One in a Thousand

Recommended Team for Day 5

Hyperbloom Team

Hyperbloom Team
Magishroom	Bongo-Head	Stormstress	Rocksteady

This Hyperbloom team is the most well-rounded team we recommend! Rocksteady works as the flex member of the team, providing sustain thru its shield, which can be helpful against the Ironbreach mechanici. The remaining Fungi can easily proc Hyperbloom/Quicken/Spread, as well as provide buffs and heals for the team.

How to Defeat One in a Thousand

Utilize the Mystic Mechanici

The Mystic Phantasm and Freezing are friendly mechanici that can easily apply their corresponding elements to nearby mechanici. Although their reach is limited, they can easily help you set up elemental Aura to trigger reactions.

The Mystic Phantasm in the first phase can help you apply Hydro to trigger Bloom, which could then be triggered by Stormstress for a Hyperbloom! And although the last two phases uses Mystic Freezing, you can still trigger Supercharged, especially if your other Fungi are attacking other Mechanici!

Use Rocksteady to Poke Outlying Units

Since Rocksteady is the flex member of the team, you can command him to poke damage on an outlying Mechanicus, particularly those far from any Mystic mechanici. We recommend doing this strat when there are Enhanced Mechanici around, however!

Keep in mind that when your team's HP is running critically low, Rocksteady can still provide shields even if its far from its teammates!
