Dimension for those who would like to survival as a water creature
The dimension is meant to complement your survival as an water creature.
The mod does not add the water creature mechanic, only the environment.
TIP: You can use Origins for this, for example.
You're expected:
- 4 biomes
- various water-friendly decorations (including underwater doors)
- underwater farms
- aggressive and neutral fauna
- some secrets
- resources
- mini-boss
To change the chandelier you need to use the flame opal gem on the right mouse button.
(or amethyst, in case of amethyst chandelier)
To call boss you need a special item “crowned jellyfish” for summoning, as well as find a shrine and use the item on the altar.
- while the boss is alive, if you are in the world of deep waters but not in water - you will be hit by lightning.
- If for some reason the boss is missing and is not summoned, or in case of a bug the boss debuff continues to hit you with lightning.
