Hidden Boss Locations

[Matutd]

So did anybody else manage this yet?

Not very clear, but yeah I got every single one
Locations:
Xaxis - fathom crypt - mega maze mash up - dark forest achievement

Zyla doom - balefort castle - hidden passage 4

Vyxnaar - fathom crypt - the forbidden crypt

Skeller krunch - fathom crypt - a secret passage

Fridge - lost expedition - a hidden ice cave

Shadow demon - shadow caves - cave of shadows - ao1 achievement

How to find them:
Mega maze mash up - you can enter this area from the join game screen or host a game in this area

Hidden passage 4 - as you enter balefort town, turn a full 180° and walk until you can turn right. Make the right turn and there should be a grid right in front of you, enter it.

Forbidden crypt - do the same as you would for hidden passage, but run straight past the grid and go through the portal. After entering the portal, run straight ahead until you are forced to make a turn, turn right.

A secret passage - Enter Fathom Crypt town and go into the sarcophgus

A hidden ice cave - in the lost expedition town there is a guy called Ryom. Behind his shop is the grid that you need to enter to reach the area.

Cave of shadows - in alien oasis town, go to the museum and turn right into the place where you craft the mystery weapons. Enter the grid in the corner.
