There are currently 5 gods in Nevermine.
Selyan
Selyan is the god of nature. His interests concern plants, trees, and other foliage-related things. The tribute bar for Selyan is located at the very top, and is colored green.
In the Overworld, in order to fill the tribute bar up and please Selyan, the player has to harvest 50 crops. If the player manages to get the bar completely filled before nightfall, Selyan will reward the player with a Resistance buff. Note that Selyan's tribute bar will go down if the player chops down trees. In the Ancient Cavern, the player can increase Selyan's tribute bar by killing Flower Faces. It takes 50 Flower Faces to fill the bar up completely. Once the bar is completely filled up, the player will receive a Resistance buff.
Selyan currently controls 5 dimensions, all of which contain heavy amounts of foliage. These include Precasia, Mysterium, Gardencia, L'Borean and the Lands of Lelyetia. In a future update, Selyan will co-rule the Everland alongside Luxon. Whenever the player enters these dimensions, the player will receive a Resistance buff from Selyan.
Selyan's guardian in the Ancient Cavern is Coniferon. To fight Coniferon, the player has to have level 70 Augury, level 70 Infusion and a full Selyan tribute bar. Once the player has all these things, they can fight the boss by right-clicking a Selyan Shrine. Coniferon drops various Selyan-themed items when defeated, such as the Selyan Scythe, Selyan Stickler and Selyan Banner.
Luxon
Luxon is the god of light. Luxon's tribute bar is underneath Selyan's but above Erebon's and is colored blue. To please Luxon, the player can either smelt items, capture Pixons, or use Essences on an Ascension Shrine. The player must do 50 of any of these activities alone or combined in order to get a full bar. If the bar is filled when night falls on the world, then Luxon will reward the player with a Regeneration buff. Keep in mind, Luxon's tribute bar will go down if the player kills mobs with melee weapons. In the Ancient Cavern, the player can obtain Luxon tribute points by killing Automatons. The player must kill 50 Automatons to get a full bar.
Luxon currently controls 3 dimensions, all of them seem to be light-hearted concepts. These include the Haven, the Lands of Runandor and Candyland. In the next update, Luxon will also control the Shyrelands. In a future version, Luxon will co-rule the Everland with Selyan. When the player enters these dimensions, the player will automatically receive a Regeneration buff. In the next update, Ambient Pixons spawn in all dimensions controlled by Luxon.
Luxon's guardian in the Ancient Cavern is Horon. To fight Horon, the player has to have level 70 Augury, level 70 Runation and a full Luxon tribute bar. When defeated, Horon will drop a few Luxon-themed items, such as a Luxon Stickler, Luxon Scythe or the Luxon Banner.
Erebon
Erebon is the god of darkness. Erebon's tribute bar is underneath Luxon's but above Pluton's and is colored red. To please Erebon, the player has to kill mobs with melee weapons. The player has to kill 50 mobs in order to get a full bar. If the bar is filled when night falls on the world, then Erebon will reward the player a Strength buff. In the Ancient Cavern, the player can obtain Erebon tribute points by killing Bloodsuckers, and in Immortallis, the player can obtain Erebon tribute points by killing Skelekytes, Skeledons, Urvs, Visages, and Ghastus'. The player has to kill 50 of these mobs in order to get a full bar (Note that Skelekytes and Skeledons will only get the bar filled up halfway).
Erebon currently controls 6 dimensions, all of them are very dark and evil. These include the Nether, the Abyss, Greckon, Dustopia, Vox Ponds and Creeponia. Erebon also co-rules Immortallis with Pluton. When the player enters these dimensions, the player will automatically receive a Strength buff. If the player attempts to place any blocks in Immortallis, Erebon will scold the player, and set the player on fire.
Erebon's guardian in the Ancient Cavern is Penumbra. To fight Penumbra, the player has to have level 70 Augury, level 70 Hunter and a full Erebon tribute bar. When defeated, Penumbra will drop a few Erebon-themed items, such as a Erebon Stickler, Erebon Scythe or the Erebon Banner.
Pluton
Pluton is the god of treasure. Pluton's bar is at the very bottom, and is colored yellow. To please Pluton, the player has to get Foraging and/or Logging drops from mining stone or breaking wood, or extract items from lava with an Extraction Device. To fill up the bar completely, the player has to get 50 drops from either Forging/Logging or both combined, or the player has to extract 100 items from lava. If the bar is filled up before nightfall, Pluton will give the player a Haste buff. In the Ancient Cavern, the player can obtain Pluton tribute points by killing 50 Rock Critters. In Immortallis, the player can gain Pluton tribute points by using Impure Gold on a Gold Accumulator, or by using Pure Gold on a Pure Gold Accumulator.
Pluton controls 6 dimensions, they are either themed around mining or do not fit the theme of another god. They are Iromine, Lunalus, the Deeplands, Barathos, Celeve and Crystevia. He also co-rules Immortallis alongside Erebon. When the player enters these dimensions, the player will automatically receive a Haste buff.
Pluton's guardian in the Ancient Cavern is Goldorth. To fight Goldorth, the player has to have level 70 Augury, level 70 Foraging and a full Pluton tribute bar. Goldorth may drop several Pluton-themed items, such as the Pluton Scythe, Pluton Stickler or Pluton Banner.
Krasaun
Krasaun is the god of equality. To please Krasaun, the player must fill up all of the tribute bars at least halfway or more before nightfall. If the player manages to do this, the player will be rewarded with 3 Gold Coins and a temporary Health Boost II buff.
Krasaun currently doesn't control any dimensions. In a future update, it is most likely that he will control Labricon. Unlike the other gods, Krasaun doesn't have a guardian in the Ancient Cavern.
Krasaun is considerably more "active" than the other gods towards the player. He will talk to the player when the player right-clicks the five Realmstone Fragments onto the Recreation Station. He does have one weapon themed around him: the Krasaun's Dawn. In the 2.5 snapshot, Krasaun will punish players who attempt to fly during most boss fights. In the 2.5 snapshot there is also a block called a "Krasaun Communicator".
