A list of the 24 Artifacts you can find during the game and what they all do.
The Bonus Artifacts (-difficulty)
Planets store double health
Gloves of Infinite Gardening
Instant planting
One of the rare ones! Play on a difficult mode to find this.
Fairy Water
Less enemies
Goggles of Destiny
See NPCs and bosses on the map
One of the rare ones! Play on a difficult mode to find this.
NPCs will be indicated by planetary rings, bosses by a red dragon head
Blue Ring
Touch damage cut in half
Breakfast Diner Stool
Find egg on first planet
One of the rare ones! Play on a difficult mode to find this.
You’ll still need to find the planet it wants to hatch on.
Lotus Flower
Health refills when not shooting or carrying a sword
One of the rare ones! Play on a difficult mode to find this.
Enchiridion of Insults
Enemies have less HP
Ancient Breakfast Cereal
No wasp hives
Don’t lose weapon powerups
Hammer of Leapmen
Instant base building
One of the rare ones! Play on a difficult mode to find this.
Compressed Gas
Fast jetpack refill
The Malus Artifacts (+difficulty)
More evil plants
Note only ultranovas can get rid of the spiky stem evil plants leave behind.
Conch Shell Kazoo
No weapon powerups
Completely harmless if using Illumina sword or the Interstellar Superweapon.
Chaos Emitter
More aggressive enemies
Wart Star
Enemies have double health
Deaths Drum
More enemies
Electro Magnetizing Pulsifier
No ultranovas allowed
Opening a chest still emits one free ultranova even if this is active.
Unfinished Blueprints
No bases allowed
You cannot construct any lasers, towers, shields or (worst of all) moai.
Frying Pan of Yore
Exist in a universe without eggs
Unvarial Pendant
Double touch damage
Eye of Sinistax
Jetpack only refills with kills
Ancient Income Tax Form
No currency
No crystals will drop. A bad one to use if you ever hope for the RRSP achievement.
Mutagen
Completed planets don’t heal you
Even worse than the “No structures” blueprints! No special achievement for completing a game with this active, either. (Phew!)
