Arknights: Endfield Trophy Guide & Roadmap

Earn all other trophies in Arknights: Endfield to unlock Platinum. Microtransactions/DLC are not required, everything is doable with the free-to-play content.

Up to Exploration Level 3 the level is increased automatically from progressing Chapter I of the main story. After this you must complete specific Protocol Space missions that become available which will increase the Exploration Level further. Once you upgrade your Exploration Level it can only be lowered by one, so before trying the Protocol Space mission you should make sure you have whatever main team you are playing upgraded almost as much as they can be

This trophy is awarded for completing all stages in the “Inorganic Construct” and “Those Forsaken by the Land” sets in Umbral Monument on Agony difficulty.

Umbral Monument is the first “endgame” mode being added to the game, that functions somewhat like Spiral Abyss in Genshin Impact or Shiyu Defense in ZZZ. It is started from the Umbral Monument icon that appears in The Hub in Valley IV once you are able to participate in it. There are two sets of three stages, with each stage requiring you to defeat a certain number of enemies while having a specific combat effect such as you constantly taking poison damage, enemies dealing increasing damage the longer they are alive, or fighting unique boss setups not found elsewhere in the game. Normal difficulty has enemies capped at level 60, whereas Agony difficulty has enemies capped at level 90 and you cannot use any healing items. At launch these fights only require one team of 4 Operators, and you have 10 minutes to finish each fight with no other requirement than completing them without dying.

When getting set up for these fights you want to make sure you have a team that is fully leveled and geared for Agony difficulty. All 4 Operators should be Elite 4 with all skills upgraded to level 9. You can leave your off characters at level 80 with level 80 weapons, but you want to have your main damage dealing character upgraded to 90 with a level 90 weapon, and try to grind for a Weapon Essence that matches their main weapon in stat bonuses, and try to upgrade it if you have extra Essence. You can upgrade the Mastery levels on skills in your main damage dealer’s Ability Matrix if you want, but this currently isn’t as needed and is more for long term if you want to fully min/max a character. If it better currently to focus on making sure everyone on your team is leveled to Elite 4 and all skills are at level 9.

Make sure all characters have a full set of gold gear with an active set effect (from equipping 3 pieces from the same set) and try to have stats contributing to their main two (shown with the yellow and grey icons in their character stats). You only need to have three of four slots filled with the same set items for the set effect to apply, so you can use a 4th slot for a random other item if it has better stats to give. You can also use two of the same items in the Kit slots if it is helpful for stats, they don’t need to be different for set effects to apply.

While doing the actual fights on Agony difficulty the biggest thing is to be aware of your health. Equipped healing items cannot be used on Agony difficulty, so your only potential source of healing is if you have a healer such as Ardelia in your current party. This also means that if a character is knocked out you can’t revive them, and if your main damage dealer is knocked out early you are better off starting over and trying again. Because of the long 10 minute timer though you have plenty of time to be careful, and if you are nearly finished and have your main damage dealer knocked out you can still try finishing if you think you can get by with your remaining characters. The stages still count as complete even if you finish with only one character left active.

This trophy is for completing the main mission Intermission: Conference of the Four, which occurs at the end of the Valley IV section of the main story.

This trophy is for completing main mission Chapter II – Process II: Where Danger Sleeps which is the final story mission available in the Wuling section of the story released with the 1.0 version of the game.

This first is all TP Points in the Aburrey Quarry area. This is a side region within Valley IV that isn’t visited at all during the main story, but is related to a rather involved side quest chain starting from side mission Quarry Rescue.

The second is the two points located in the Rockill Passage area which is on the north side of The Hub, directly east of the Core AIC Area. This area is blocked off by a closed gate until some time after you complete Chapter I – Process III: Mystery in the Building. Currently the exact requirement for this opening is unknown, as some people seem to have it unlocked after this quest and some don’t. If it’s not open for you try coming back later after completing the Valley IV story or completing other side quests in the area.

When you are starting out your Operators’ max level is blocked by your current exploration level. You will need to reach Exploration level 6 to be able to upgrade Operators to Elite 4, along with upgrading their level to 90.

Upgrading level uses two different sets of XP materials. From level 1 – 60 you use the three Combat Record materials. From level 60-90 you use the Cognitive Carrier materials. As of launch there isn’t a way to convert these into each other or use one in place of the other. You can farm both of these types of materials from Protocol Space: Operator EXP missions using energy.

Upgrading Elite levels requires either Protodisks or Protosets, which are materials that can be farmed from Protocol Space: Promotions using energy, along with different rare materials collected from Gathering Sites. These are represented by round hump icons on the map labelled Rare Growths, and each will show the items that can be collected there. As you upgrade your exploration level this increases the cap items at each spot and how many regrow: at launch in all spots this is a cap of 8 pickups, regrowing at a rate of 2 per 24 hours at Exploration level 7. For all launch period characters materials for upgrading to Elite 1 and 2 grow in Valley IV, whereas materials to upgrade to Elite 3 and 4 grow in Wuling. This is likely to change in the future when new areas and characters are added, so if you are unsure you can view the upgrade screen for a character, then by selecting the material view the locations where it is available from which will point it out on the map.

When you are actively playing every day you want to make sure you are collecting all items as they grow. At Exploration level 7 you can leave Rare Growth locations for 4 days at a time, then when you view the map for an area it will show in the Mission Reminder menu on the top left if there are full locations, and when selected will point you directly to them. You can also grow items in the Growth Chamber on the Dijiang, but these generally only grow at a rate of 1 pickup every two days, so you will want to make sure you are still grabbing the growths from the open world as you are playing.

Weapons only have three types of XP materials (Arms Inspector, Arms INSP Kit, Arms INSP Set) and can be used to level a weapon at any time, there isn’t different sets for different level ranges like Operators. These can be farmed from Protocol Space: Weapon EXP.

Upgrading tiers functions the same as upgrading Operator Elite levels, but using different types of materials. They need Cast Dies or Heavy Cast Dies which function the same as the Proto items and can be farmed from Protocol Space: Weapon Tune, along with different materials from gathering sites. These are represented by an icon on the map that looks like a snail shell labelled Rare Ores, which function the exact same as the Rare Growths, and are split the same way between Valley IV and Wuling for weapons available during the launch period.

This trophy is awarded for completing all stages in the “Inorganic Construct” and “Those Forsaken by the Land” sets in Umbral Monument on normal difficulty.

• Refugee Camp – This is automatically connected during the main story in Chapter I – Process I: Building an Outpost.
• Infra-Station – This is connected during the side mission Outpost: Infra-Station.
•  Reconstruction HQ (Planned Construction Area) – This is connected during the side mission Outpost: Reconstruction HQ.

To earn this trophy you first need to make sure all possible locations have drills placed on all possible spots, and they are all powered. You won’t be able to do this immediately in each area, as the amount of spots in certain locations is determined by your Regional Development Level. You should be aiming to max out your Regional Development Level in each region, as this gives extra rewards and unlocks other features. Regional Development level is increased by placing and powering drills on mining spots, upgrading Outposts, Recycling Nodes, Depots, and Stock Redistribution Stations, and by completing some missions.

Once you are sure you have placed and powered drills on all possible spots, you will need to make sure that all of them are working at the same time. Depending on your manufacturing setup you are very likely to be mining more Originium, Amethyst, and Ferrium than you are actually using, which means that your drills will be starting and stopping as material is slowly pulled for manufacturing.

Once you have set up your Depot Nodes, this allows you to package and ship materials which are then delivered to locations in exchange for Stock Bills. You can use the three mined materials as materials to ship, so if you do all three at once you’ll remove enough material from your depot to have all mining drills working at once.

If you can’t do this, you can also open the Valley IV Depot inventory and specifically destroy the mined materials, but this isn’t generally recommended.

This trophy is for completing the main mission Chapter I – Process I: Awakening, which is the mission completing the prologue before you enter Valley IV, the first overall region of the main story.

This trophy is automatically earned during main mission Chapter I – Process III: Lodespring Crossing as you are working on destroying the Ankhor cores in the Origin Lodespring area.

This trophy is for completing the main mission Chapter II – Process I: Arrival at Wuling, which is the first main mission that occurs in Wuling, the second overall region of the main story.

Upgrading the Control Nexus is primarily blocked by story progression. As you progress the main story you will be awarded a material called Algorithm Expansion Chip, which is required to continue upgrading the Control Nexus. You will be awarded the final one that allows you to upgrade the Control Nexus to level 5 after completing main mission Chapter II – Process II: Where Danger Sleeps which is the final story mission available in the Wuling section of the story released with the 1.0 version of the game.

The other materials that you need to upgrade the Control Nexus are Aerospace Material I/II. These materials are obtained from the Recycling Stations throughout Valley IV and Wuling, represented by owl icons on the map. After they are activated they can be upgraded using the regional Stock Bills, which increases the number of materials that can be collected from them each day.

Note that Wuling AIC I corresponds to the top section of the Wuling AIC plan that is available with the 1.0 release of the game. When more is added in the future it won’t be required for this trophy.
