Welcome to another trinket hunt in Factions world! This hunt involves exploring the oceans of the world, as the rewards are four trinket that let you stay underwater indefinitely.
Hunt details
Four Diving Helmets have been hidden in each quarter of the world as such:
Each of them is in a chest underwater, with nothing else in the chest.
The chests are below the sea level.
Some are visible from the sky, some are not.
You don’t need to break any block to reach the chests.
Note that unlike the hunt for the Invisibility Tunic, there can be factions and player structures near the chests.
Hints
To find the four trinkets, you have the following hints:
The northwestern corals hide a deep dark secret.
The wizards from the northeast have no idea that X marks the spot.
In the southeast, two opposing waters meet.
In the southwest, a very special atoll is forming.
Trinket description
The Diving Helmet is an iron helmet that can’t be repaired (at least for now). It works by preventing damage taken from drowning, that is, your air meter running out. Note that it does not protect you from suffocating (taking damage from being inside blocks).
