The game developers have stated that void crusades won't be changed or added, so I'm not expecting any major issues with the paths getting outdated.

The last round of updates to my void crusade guides was done with the game at patch version 2.3.4, during the Season of Warp Surge.

This guide was last updated in April 2021. I added a bit more general Void Crusade information, and added the Relic farming part.

What changed:

• I changed my steam name, to bring it in line with reddit, the game and discord.
  
• The season objective with all Info Fragments got changed to 75 minutes (was 60 in the Season of Inferno)
  
• A Versioning/Update history section was added
  
• An Info section was added
  
• All guides got (roughly) the same format
  
• Amber got an Info Fragment path, and a discussion of its merits
  
• Viridian got a Relic farming route

• Bonus, Secret and Covert missions add a higher bonus to loot than regular missions
  
• Starting with the Season of Warp Surge, item levels will go up to 100. You need to do missions of at least +7 difficulty to get level 100 items, if you are 100. I have yet to find out - all other things being equal - whether an extra Tarot card, or extra difficulty would lead to more level 100 items
  
• I'm pretty certain the Servoskull can not spawn right next to the starting node on the VC map, but it can spawn one node away. Apart from that, it seems random. And you can get unlucky, and it will shop in a high difficulty mission, in a room full of Elites
  
• In almost all cases, the Servoskull is exactly in the direction you were facing/moving when you got the notification

• You will NOT get the info Fragment if you pick it up, and then concede the mission
  
• The mission timer starts when the missions starts (not when you launch it)
  
• The mission timer stops when you fulfill the mission objective (not when you leave the mission)
  What that means for you: Do mission objectives first, until you get the 'Quit' popup. Then go hunt for cogitators and Info Fragments

• If you die AFTER the mission objective has been fulfilled, the crusade continues
  
• Abandoning a mission ends the hardcore crusade
  
• Failing a mission (that includes hot pursuit and vip/guard rescue) ends the hardcore crusade Rescue missions get very dicey around +6, depending a little on Tarot Cards and enemy type

• Two keys are granted for finishing the Supreme Mission
  
• A key is granted after completing five missions of any kind
  
• A key is granted after completing at least two Bonus missions
  
• A key is granted after completing all Covert and Hidden missions
  
• A key is granted after defeating the Wandering Servoskull

• Dataslate Decryption Terminals don't have a map icon. Use Vrakos' guides if you get stuck
  
• Cogitators for secret missions don't have a map icon. However, they are always in a 'secret' room you have to teleport to
  
• 'Survivors' are in a group of guards, and one of them has a label of 'Survivor' when you hover over him
  
• Hot Pursuit: Keep your mouse over the fugitive, and hold down the magic new button you have (usually '5')

• I always make my paths with the difficulties peaking in the middle, and then working down from there. It has been pointed out to me that that's not fully optimal, because some missions give bonuses for subsequent missions after completion, like '10% extra damage vs. Rebels'.
  My take on that is: If you are really, really struggling to finish the missions, the bonuses might actually help you a bit.
  At the same time, if you are really, really struggling with some normal missions on Void Crusades, my advice would be to hop onto Discord and to ask for help.
  And, my focus when doing Void Crusades is gaining loot from the Supreme Mission. The quantity of Relics goes up with difficulty, and we will also get more level 90+ items. So I'm bumping up the difficulty there, and by the time we are at the Supreme Mission, we will have also collected all the bonuses.
  
• As of this patch, the highest possible difficulty you can run a mission at is +29, and it's on the Crimson Void Crusade
  
• For regular (and Supreme) missions, the difficulty gets set when the mission is made accessible
  
• For Secret and Covert missions, the difficulty gets set, then the difficulty modifier is added for subsequent unlocks

Amber 4
Amber 12

This is the best way to farm Tarot Cards I have found so far.
I made three runs yesterday and got 31, 42 and 47 Tarot Cards.
Run in Hardcore. The final mission is a +4.
What also helps with getting even more Tarot Cards: Loot Quantity rolls on gear. And high levels of the tarot cards. I'm at Level 3 for the double item cards, Level 5 for Tarot drops and 169% Loot quantity.

Watch out for the Servoskull appearing in mission 2! It never spawned for me, and waiting after fulfilling the mission objective made the game crash. The only way to finish the mission in that scenario was to do the mission, and then to hit 'Quit' the very instant it was available

One key for five mission - we do seven (or eight).
One key for two bonus missions - we do two.
Two keys for the final mission.

So four keys at the very least.
There's a fair chance that we spot the Servoskull in a mission. We will unlock the final mission, and then tackle the Servoskull for a fifth key.
We have three Info Fragments. That means we will either already see which void chest contains the Tarot Cards, or we see that none of the known ones have it, and then we unlock the majority of the unknown ones, and have a good shot of hitting the one with Tarot cards.
We run all the missions with two double item tarot cards and with the higher chance of Tarot Card card.
The 31 Tarot cards was with just the Supreme Chest and a miss on the Tarot Card chest.
42 and 47 was with Supreme and hitting the Tarot Card chest.

There is a path for Viridian (included in my Viridian guide) with 12 missions, and a higher difficulty Supreme mission. However, there are many big maps on this Amber path, while the Viridian one has smaller maps, Nurgle (easier to kill, and less ranged DoT) and a nice amount of Nurgle Demon Hosts, which drop very good loot.
I have now run both Info Fragment paths several times, and my conclusion is as follows:
If you move slowly, but increased difficulty doesn't slow you down much, do Viridian.
If you move quickly, but increased difficulty slows you down, do Amber.

• 99 doing this as well (if you have the time) gives an extra key, and increased/better loot
  
• 98 doing this as well (if you have the time) gives a lot more and better loot
  
• 11:+2 Bunker Busting. There is an unidentified blueprint smack in the middle of the map. First (and so far only) time I found it, it dropped two archeotech blueprints.
