How to Beat Waterbag Barrier

Recommended Team for Day 3

Melt-Burning Team

Melt-Burning Team
Gusto-Frosto	Magishroom	Duelblaze	Twirly-Whirly

Gusto-Frosto and Magishroom are your core members to take down the pesky shields that the large Hydro Mechanicus creates. Gusto-Frosto is a reliable Cryo applicator whose attacks you should should spam especially for Mechanici that are close to each other.

Combine Dendro and Cryo with Duelblaze's attack to deal both Melt and Burning damage! Magishroom will also heal the Fungus with the lowest HP so you can slot in Twirly-Whirly or Rocksteady instead of Bongo-Head this time!

How to Defeat Waterbag Barrier

Go in-between Mechanici

In the first phase, three Mechanici will spawn far apart each other, you can order Gusto-Frosto to go in-between two Mechanici to apply Cryo, then focus on each enemy at a time!

We recommend holding your Marvelous Gels until it caps or until the large Mechanici arrives.

Apply Cryo and Dendro to Remove Shields

The main threat in this stage is the large Hydro Mechanicus, who can give shields to its nearby allies. Luckily, you now have a Dendro and Cryo shroom that can easily take care of it! Once you apply both elements, finish it off with your Duelblaze!

Order Gusto-Frosto to the middle

Gusto-Frosto is especially useful in Phase 2. Order it to attack while in the middle of the four Mechanici to apply Cryo. If there are shields, Gusto-Frosto together with Magishroom will take care of it easily!

Watch out for the Large Pyro Attack

At the very last phase, watch out for the delayed AoE attack that the large Pyro Mechanicus readies to a Fungus. Once this happens, order the fungi underneath to quickly sprint out of it!
