Haven – How to Spawn and Fight Beruberu Secret Boss (Thar She Blows Achievement)

The secret boss for the hardest achievement Thar She Blows. This guide is compiled from other sources and have been test by myself a little bit.

Guide to Spawn and Defeat Beruberu

Facts

The boss:

• The boss can spawn on clean island. No rust needed.
• The boss will spawn after characters are non-sleep for 24hrs in game, 24mins in real life.
• Sleeping at a campfire outside reset the spawning timer.
• However, once the boss spawned, sleep at a campfire does not despawn her (haven’t test sleep back at the nest yet.).

Misc:

• Red for blast.
• Green for impact.
• Every resource is capped at 99. So be sure to cook/transform them into food/potion rather than stack them up too much.

Spawn

I’d suggest maxing out the relationship first before decide to confronting the boss. So you’ll have max HP and combat power. Also choose a map with campfire and clean surrounding maps (rust and monsters) — prevent unnecessary HP loss by running into monsters.

When you ready to tackle Beruberu. Go back to the nest and make 5 healing balm and 5 speed tonic.

No need to make omni-thing, but having them when there’s spare resources is ok.

Prepare Some Top-Tier Foods

Eat. Sleep. And when you wake up, grab some food with you (2 basic food as a round-trip ticket for our sky-bus, at least 1 best food for picnic later at the camp.) and go out.

Go to a map with camping area. Stay near the bridge to other map. AFK for ~22 minutes. Then change map to trigger save game. (Optional: go back to the main screen and bump up save file if you wish.)

Now, just wasting time around in game. The characters might complain about their hunger. You might hear a roar and feel earthquakes. Just keep wasting time for about 1 minute. If she not spawn yet, change map (prefer the non-campfire one) and continue wasting time.

When she does spawn, I think it will happen when you change into a new map such that she will fly out from the bridge that you’ve taken (I’ve experience this first hand and saw in some guide videos). Luckily that she’s so slow. So fly away from her in a way that she’s not block the bridge (Optional: back to main screen to manipulate save files.).

Avoid her and fly back to your camping area. Eat. Sleep. Wake up and go back to the map she spawned. She’ll waiting for an epic fight there. However this fight will be a lot easier than other guide since your stomach is full!

Fight

In general, apply tonic to increase charge rate. Don’t forgot to re-apply it every now and then.

There are 3 phases of the boss fight.

First phase: DUO burst first, the DUO impact second. Rinse and repeat.

Second phase is observing aura:

• Red for DUO blazeburst.
• Green for DUO impact.

Don’t aim for full charge. Just the basic one is ok. The most important thing is trying to get the spinning wheel to land on the right spot.

Third phase is spamming burst one after another (avoid using DUO burst since it’s take too long to charge) to mainly get the boss in stunt-lock. And when she charge up a terrifying laser attack, shield up both characters.
