¶ Alien Invasion
The crystal that opens the way to them.
The Alien Invasion is content that appears in the middle of your hunt. You do not need to look for it or leave where you are. While you kill monsters, there is a chance for a crystal to appear near you, and what happens next is your choice.
This content has two parts: the prismatic crystals, which appear in any hunt, and the alien artifacts, which are spread around the Eternal Depths.
¶ Prismatic Crystals
While you are hunting, there is a chance for one of these crystals to appear. They are strong, so activating one or not is your decision. Nobody has to face the fight, and the crystal only does something when you interact with it.
When you interact, a portal opens and an Alien comes out of it. These creatures come in seven different colors, and each color is a different fight, with its own mechanics. Depending on your class, some colors will be easy and others will be much harder.
The Alien also adapts to the place where it was called, so the same color will not be the same experience in every hunt.
¶ What the Alien Gives
Defeating an Alien gives you three things at once:
Alien OrganDropped on each kill. The color of the organ comes from the map where you are, not from the color of the Alien.
Advances 20% of the task progress of the creature you were hunting at the moment.
A temporary buff of 5 minutes. It is worth hurrying to use every minute.
If you are doing the Hydra task and a crystal appears in the middle of the hunt, killing the Alien advances 20% of your Hydra task. It works for any task you are doing at that moment.
Because it follows the region, each map drops a different organ. If you want a certain organ, you need to hunt in the right place.
¶ Alien Artifacts
All over the Eternal Depths you will find these artifacts. They work like an ore vein, but the way they move is too strange to miss. You will recognize them from far away.
There are hundreds of them per map, so there is always something to break. When you interact with an artifact, one of two things happens:
You collect the crystals of that map right away.
A group of aliens wakes up and comes at you. Defeating the horde also drops crystals.
So both ways give crystals. The difference is the work you need to do to get them.
¶ Crystals of Each Map
Each map in the Eternal Depths has its own crystal. The deeper the map, the more valuable the crystal is when you trade it.
This makes the choice of map important. Farming in a harder place gives better crystals, but it asks more from you. Think about what pays off more for your character.
The crystals are traded with the NPC Annabri, and almost everything good in this content comes from her. The full list is right below.
¶ Annabri
Annabri, in Shallowrift.
Annabri is the NPC that closes the cycle of the alien content. Everything you collect while hunting becomes a deal with her. She is in Shallowrift.
You trade with her using two things:
From the alien artifacts of the Eternal Depths.
From the Aliens that come out of the prismatic crystals.
The crystals can also be traded with her for trade currency. So even if you do not want anything from the store right now, what you farmed does not sit idle.
¶ Annabri's Store
This is the list of what you can buy from her:
| Item | What it is for |
|---|---|
| Set resources | Material to upgrade sets, like Shard, Blood and so on. |
| Rarity Token | Used in the equipment rarity upgrade |
| Chaos Essence | The currency of the Chaos System |
| Relic T4 | You can buy a T4 relic from her, but at a HIGH cost |
| Tree | Progress in the Alien Skill Tree, explained at the end of this page |
| Dungeon and HG | Maximum charge of dungeon and of hunting grounds |
| General bonuses | Bonuses in the same style as the Orb tower, like drop chance and others |
| Trait Bloodrite | Trait of the Bloodrite set |
| Summon Raid Boss | Calls a raid boss for your party to fight |
The list mixes fast progression items with late game items, so choose what helps your character now.
¶ Alien Skill Tree
The Alien Skill Tree is the most important part of all this content. It is a new progression tree for your character, and it grows with the same things Annabri wants: crystals and alien organs.
If you make a mistake in your choices, you can reset the tree. The reset has a waiting time, so it is not something to do all the time, but it is not a decision for life either.
¶ The Seven Paths
The tree has seven paths, each with a color and a focus:
| Path | Focus |
|---|---|
| Red | Damage |
| Orange | Alien Gunner, a helper alien that fights by your side |
| Yellow | Harvest |
| Green | Resources, joining hunting grounds and dungeons |
| Blue | Double Task |
| Indigo | Rift |
| Violet | Pearl & Soul Stealer |
Even in the late game, with everything at maximum, you can complete about four paths. So every choice here matters.
Each player has their own way of playing, and each path shines at a different moment. Think about how and when you play before you spend the points, and remember that the reset is there in case you change your mind.
