Warframe Deep Archimedea Reset on September 28, 2026 is the first weekly rollover that will use the new four-group Personal Modifier system revealed in Hotfix 44.0.1. The reset happens at 00:00 UTC, and one Personal Modifier will be randomly chosen from each of four groups instead of the game drawing the whole weekly set from one unrestricted pool.
That makes this reset more important than a normal weekly refresh. It is the first time players can see the grouping rule working in the live Archimedea menu, and it arrives alongside the wider Update 44 changes to Research Points, Arsenal Bonuses and the reward track.
Warframe Deep Archimedea Reset: September 28 time and first grouped roll
The September 28 Warframe Deep Archimedea Reset occurs at midnight UTC. Digital Extremes uses Monday 00:00 UTC for Archimedea weekly refreshes, and Hotfix 44.0.1 explicitly names September 28 at that time as the first activation of the new Personal Modifier Groups. Iceblade of Narin launched on September 23, which was too late to alter the modifiers already selected for the current week.
| Reset detail | What to expect |
|---|---|
| Date | September 28, 2026 |
| Server time | 00:00 UTC |
| UK time | 1:00 AM BST |
| Personal Modifiers | Four total, one randomly selected from each group |
| Applies to | Deep Archimedea and Temporal Archimedea Personal Modifier generation |
| Exact weekly combination | Unknown until the reset rolls it |
If you open the mode shortly before the Warframe Deep Archimedea Reset, you will still be looking at the pre-grouping weekly selection. There is no manual activation step. Once the server crosses the weekly reset, reopen or refresh the Archimedea screen and inspect the new Personal Modifiers.
How the new four-group selection works
Hotfix 44.0.1 divides the Personal Modifier pool into four groups. At weekly reset, the game randomly chooses one modifier from each group. The change is designed to reduce unusually harsh combinations where several penalties attack the same part of your loadout or survivability at once.
The Warframe Deep Archimedea Reset does not make the modifiers predictable. You cannot know which entry from Group One, Group Two, Group Three or Group Four will appear before the roll. What you can know is the structure: the week should contain one modifier from each group rather than multiple selections all taken from a single category.
| Group | Examples of what it can target |
|---|---|
| Group One | Broad combat penalties, weapon restrictions and movement or damage pressure |
| Group Two | Ability duration, range, energy and ability access |
| Group Three | Ammo, Gear, Companions and Transference |
| Group Four | Shields, armor, health recovery and survivability |
For the full named list, the separate Personal Modifier Groups guide breaks down all 25 entries. The important reset-day check is that all four active modifiers map to different groups. If that structure is present, the new selection system is working as described by Digital Extremes.
What else changed in Deep Archimedea with Update 44?
The Warframe Deep Archimedea Reset lands after several broader Archimedea changes introduced in Iceblade of Narin. Warframes and weapons that match the weekly Individual Parameters can receive Arsenal Boosts, and the Research Point track has been expanded. These changes are separate from Personal Modifier Groups, but they affect how you decide which restrictions are worth accepting.
The maximum in an Elite Archimedea run is now 43 Research Points. The highest reward is at 40 points, while the Legendary reward was moved to 37. Matching the listed Warframe now contributes three Research Points per mission rather than one, which gives more room to leave an unwanted parameter disabled and still reach the upper reward tiers.
What should you do before the September 28 reset?
You do not need to farm a special item before the Warframe Deep Archimedea Reset. The useful preparation is to finish any current-week activity you still care about, then wait for the normal rollover. After the reset, inspect the new missions, Loadout Parameters and Personal Modifiers before committing to a build.
- Finish any current Deep Archimedea run you still want to complete before the weekly rollover.
- After 00:00 UTC on September 28, reopen the Archimedea menu.
- Read all four Personal Modifiers and identify which group each belongs to.
- Check the weekly Warframe and weapon choices separately from those Personal Modifiers.
- Calculate the Research Points you actually need before enabling every restriction.
- Build around the harshest active modifier rather than assuming the grouped system makes the week easy.
Does the reset guarantee an easier Deep Archimedea week?
No. The goal of the Warframe Deep Archimedea Reset grouping change is to reduce excessively punishing combinations, not to guarantee a soft weekly roll. A difficult entry can still be selected from every group. The difference is that the system now spreads those selections across four categories instead of allowing the weekly set to cluster too heavily around one kind of restriction.
That means a player with a specific build can still get a bad matchup. For example, an ability-focused setup may dislike the Group Two selection even when the other three are manageable. Treat the new rule as better distribution, not as a promise that each week will fit your preferred frame or weapon.
What if the new modifier groups do not appear after reset?
If the Warframe Deep Archimedea Reset has passed and the menu still appears unchanged, first make sure your game client is fully updated beyond the Iceblade of Narin launch build. Hotfix 44.0.1 is the patch that documents the group system and confirms the September 28 activation. Restart the game after the weekly rollover before treating the display as a bug, especially if you had the Archimedea screen open across reset.
The exact September 28 combination cannot be confirmed before the server chooses it. What is confirmed is the timing and the rule behind the roll. Once the Warframe Deep Archimedea Reset happens, one Personal Modifier from each of the four groups should define the new weekly set, giving players a more controlled spread of restrictions while keeping the mode deliberately demanding.
Does the reset affect Temporal Archimedea as well?
The September 28 Warframe Deep Archimedea Reset is important to Deep Archimedea players, but Digital Extremes says the new Personal Modifier grouping method applies to both Deep and Temporal Archimedea. Each mode still has its own missions and surrounding rules, while the four-group generation system controls how the weekly Personal Modifiers are chosen.
That means the Warframe Deep Archimedea Reset is worth checking even if you usually skip maximum Research Points. A more structured modifier spread can change which optional penalties feel reasonable for your frame, weapons and squad, especially now that the top reward thresholds and Warframe parameter value have also changed.
After the first Warframe Deep Archimedea Reset using the new system, future weekly rollovers should continue using the same one-from-each-group rule unless Digital Extremes changes it in a later hotfix. The September 28 date matters because it is the first activation, not because the grouping system is intended to be a one-week event.
The Warframe Deep Archimedea Reset changes the weekly selection, not your account progression. The Warframe Deep Archimedea Reset also does not require a separate unlock beyond normal access to the mode.
