Advanced Guide: Sun Quest

See also: Uusi Aurinko

Prerequisites

This quest is endgame content. It involves travelling long distances around the world through very hazardous areas, culminating in the creation of one of the most deadly objects in the game. It is highly recommended, if not necessary, to have wands for fast travel, healing, and digging (ideally unlimited Extremely Dense Rock digging).

Having many protective perks will make this quest significantly safer, particularly the end part where you actually create the suns. You can accomplish this easily via "breaking the reroll machines". A total of 15 or more stacks of Stainless Armour (paired with Repelling Cape and Gas Blood to keep you free of stains) makes sundiving non-fatal.

You'll also need a Paha Silmä (one spawns guaranteed each run, but has a tendency to vanish) - can also be found in chests.

Basic Introduction

High in the sky in The Work (Sky) and deep below the earth in The Work (Hell) are moons (the Moon and the Dark Moon, respectively). You can locate them using the Moon Radar perk. This quest involves creating suns at each moon.

There are two types of suns - the "normal" Sun (which resembles a sun) and the Dark Sun (which resembles a black hole. Both are extremely dangerous to create, damaging to be near, and almost certainly fatal to be inside of.

How to make a sun

Preparing

1. Obtain a Paha Silmä (necessary for the boss fight step)
2. Obtain one each of the 4 elemental stones:
   • Kiuaskivi
   • Ukkoskivi
   • Tannerkivi
   • Vuoksikivi
3. If making a dark sun, also obtain one:
   • Kakkakikkare
4. You'll need a series of powerful explosions to ignite the new sun. Obtain one of these options (and a wand set up to cast it in under a second).
   
   Any

   1

   of:

   

   Sea Of Lava

   Summons a large body of lava below the caster

   

   

   Giga Nuke

   What do you expect?

   

   

   Summon
   Sädekivi[2]

   or

   Any

   6

   of:

   

   Bomb

   Summons a bomb that destroys ground very efficiently

   

   

   Dormant Crystal

   A crystal that explodes when caught in an explosion

   

   

   Holy Bomb

   Summons a bomb that... well...

   

   

   Giga Holy Bomb

   Bigger and therefore holier

   

   

   Thunder Charge

   A projectile with immense stored electricity

   

   

   Meteor

   A destructive projectile from the skies!

   

   

   Nuke

   Take cover!

   

   

   Destruction

   Instantly decimates foes around you, at the cost of your HP

   

   

   Explosion of Thunder

   An electric explosion

   
5. Obtain a mechanism for spawning the 100 blood sacrifices needed to nourish the new sun. You can use Summon Egg, Summon Rock Spirit, Summon Taikasauva etc. to spawn entities for it to kill. You can also create the sun somewhere with plenty of enemies nearby, e.g. Hiisi Base.
6. Obtain a Sun Seed by defeating the Ghost miniboss (Unohdettu). The boss spawns in parallel worlds and can be farmed for multiple Sun Seeds.
7. Dropping the Sun Seed at the top of the pyramid will cause it to violently explode, and evolve into a Sun Stone. The explosion has a tendency to send the stone flying off the top of the pyramid, to become lost in the shifting sands of the desert. Filling the top of the pyramid with a liquid (one that wont evaporate - Blood is ideal) mitigates this.
   
   Note that the Sun Stone inflicts proximity curse damage, but this stops if you pick it up into your inventory.
8. Decide where you want the sun to be (it is far easier to move the Sun Stone at this stage than any later stage). Finish preparing by bringing together the necessary elemental stones, blood sacrifice, and explosives. Clear the immediate area of enemies (unless you plan on using them for the sacrifice). If you are creating the sun within the moon, dig a tunnel into the top of the moon down about 1/2 of the way to the centre.

Ignition

This comprises three stages:

The detection radius for the Sun Stone to register compatible explosions for evolution.

1. Set off the explosion(s) to transform the Sun Stone into a Sun Egg.
   • The explosions need to happen within a radius of ~130px.
   • If multiple explosions are required, they must happen within the space of 1 second.
   • The transformation process destroys materials and liquids around the Sun Egg.
   • The Sun Egg will slowly dissolve away and eventually vanish - best to move it to the next stage immediately.
   • The Sun Egg can move, and may be created with significant initial velocity due to the explosives used. (Even full-grown suns are surprisingly hard to find if you lose them...)
2. Feed the Sun Egg 100 creatures to transform it again into a small version of the final form - a Star Child.
3. Add each of the 4 (5 for the dark sun) elemental stones. Each transforms the Star Child, infusing it with elemental energy and culminating with the final evolution into a Sun or Dark Sun.
   • The order of the 4 basic elemental stones doesn't matter, and you can throw them in one by one, or add them all at once by jumping into the sun while holding them in your inventory.
   • For creating a Dark Sun, you need to make sure the Kakkakikkare is added before the last of the 4 elemental stones.

Notes:

Sun damage

The Sun and Dark Sun are very dangerous - dealing huge damage to nearby entities. Four different damaging zones exist, centered on the sun:

• Fire - 915 damage per second - within a 560x560 area.
• Explosion - 1575 damage per second explosion damage - within a 380x380 area.
• Curse - 3210 damage per second - within a 244x244 area.
• Midas - (100x current hp per frame) - within a radius of 100.

The damage types are cumulative, being in the Curse damage area you'll also get the Explosion and Fire damage on top.

Note that the first 3 areas are square, and so approaching the sun vertically from above/below, or horizontally from left/right will allow you to get closer while suffering less damage. The Dark Sun is visually larger, but has the same sized damage areas, meaning you can get just inside it before suffering the extremely lethal Midas damage effect.

Associated achievements and cosmetics

The following are required for the related Achievement Pillars and the crown cosmetic:

• Create the Sun
• Create the Dark Sun
• Kill Kolmisilmä with a sun (It is advised to collect a few orbs so the boss has enough health to survive the trip)
• Supernova - Collide a Dark Sun and a Sun (they can be more easily moved with either a Kuu or Kuulokivi)
• Create a sun at both moons, with the second moon created being a normal Sun
• Create a sun at both moons, with the second moon created being a Dark Sun
  • Note that these suns must be created from the sun seed, and using those made by sacrificing the gems from the Celestial Scale will not count towards the achievement pillar. It is unknown if this is intended behavior.

Note: The minimum requirements to receive the Crown cosmetic is to create the Sun at the Moon, and the Dark Sun at the Dark Moon. After the suns are created, the Crown will appear on subsequent runs. If you move a sun away from its moon, nothing happens to your crown. No in-game action removes it after you have it.

Guide to getting all the Sun pillar achievements in one run

TLDR:

• First run: Make a New Sun at Both Moons
• NG+: Make a Dark Sun at Dark Moon (This completes the Sun Quest, and leaves both suns at their respective moons)
• Colliding the suns and killing the boss with it can be done at any stage of this quest

In Detail Explanation:

• Break the reroll machines to get perks
  • Perk Lottery x 4
  • Extra Perk x 3
  • Gas Blood - Prevents staining from the Sun damaging you. Make sure not to grab Slime Blood or Oil Blood after taking this as it will override the type of blood generated.
  • Stainless Armor x 15
  • Repelling Cape x 2 (note that taking more stacks may cause undesirable staining behavior)
  • Saving Grace

• Kill the ghost miniboss for a Sun Seed
• Place the Sun Seed on the top of the pyramid to create the Sun Stone
• Take the Sun Stone to the center of the moon.
• Summon bombs (Divide by 10 + Bomb) on it to evolve it into a Sun Egg
• Summon eggs (Divide by 10 + Summon Egg) at the Sun Egg to make a Star Child. Sun needs to get 100 kills total.
• Collect 4 essences and use the essence eater to get the elemental stones
  • Alternatively, the fire stone and thunder stone are naturally generated around the world. Pedestals frequently spawn in the fungal caverns

• Throw the elemental stones into the star child to make a new sun, or go inside it and it will grab them from your inventory.
• Repeat the above steps to make another sun at the Dark Moon
  • Alternatively, drag the sun you made at the moon all the way down to the Dark Moon. A Kuu or Kuulokivi can be used to pull the sun out of the gravitational pull of the moon.

• Start the fight with Kolmisilmä and kill it with a sun. The boss follows you no matter how far you travel and through all terrain, but can get distracted by other enemies.
  • Take the portal that spawns on its corpse to get a the Benign Sunshine achievement then exit the room

• Get another Sun Seed from a parallel world. You can get two to make supernova easier in NG+.
• Go to NG+
• Make a Dark Sun at the Dark Moon
• Use a Kuu or Stone of Hearing to drag the New Sun and Dark Sun together to cause a supernova. You can make a New Sun in hell so you don't have to drag suns through the whole world.

You'll want to make frequent backups throughout this process. Sun Seeds are not obtainable in NG+. Furthermore, items sporadically disappear off screen when they clip into the ground and when the game crashes.

Explanation of why only a Dark Sun has to be created if you opt to NG+

When the first sun is created at a moon in a run, this information is recorded and remains recorded throughout the entire run even in NG+ iterations. Therefore, you can create a sun at the other moon then enter NG+ and create only a Dark Sun at the Dark Moon rather than having to make an extra sun and then a Dark Sun. If instead you started a new run, this information is lost. You would have to make two suns.

Limitations

• There is no Ghost miniboss in NG+, so Auringonsiemen must be carried into NG+ by you.
• Entering NG+ can delete some of your sunseeds or sunstones due to a bug, but 2 sunseeds and 2 sunstones seems to be a combo that survives the trip often. Fix for this issue in the note below.
• There is only one Essence of Fire, so additional Kiuaskivi must be found.
• Essence Eaters are limited - There are six (two in the main world, two each in the first parallel worlds in each direction) in NG and only two (in the main world) in NG+.
• A moon can only "react" to one Sun per NG cycle. Further actions in that NG+ iteration will not have an effect; enter another iteration if required.

Important note: Entering NG+ can delete extra sun seeds and sun stones due to a bug. There is a mod on steam workshop that fixes this.

Additional Notes

• The supernova (colliding the Sun and Dark Sun) will transform many materials. This persists through NG+.
• The Sun will persist if it was created at the Moon and the Dark Sun will persist if it was created at the Dark Moon otherwise it will disappear upon starting a new game/NG+ iteration.
• A sun may be reverted to a moon by creating or moving the opposite sun to that moon.
• The sun egg (the stage after bombing it but before having sacrificed 100 creatures) disintegrates over time, albeit very slowly. Feed it 100 kills to stabilize it.
• You may supernova the two suns and they will still persist in their respective locations (sun in moon and dark sun in dark moon) in consecutive runs. It is the moon that remembers what is the last type of sun that consumed the moon, if the sun was the correct type, then the moon will spawn it there.
• The Moon(s) also die(s) from a single event, like one of these sun collisions, so no matter what you do in the location after, you cannot mess moon's "memory" up.
