How to Get
Killer Machine Memory is a random drop from clearing the Machine Ruins stage in the Wandering Merchant and Lost Ruins event. You can also receive it from event missions.
The Wandering Merchant and Lost Ruins event ended on July 21, 2026. Do not plan to farm this Memory unless the event returns in a rerun. If you already own it, treat it as a keep for ice physical builds.
Best Uses
Ice physical damage carry
Use Killer Machine Memory when your main damage dealer can turn the ice physical damage bonus into faster clears.
Blue Steel Machine Lance synergy
The effect lines up well with accounts that already have or are building a Blue Steel Machine Lance weapon route.
Yellow slot value
It is easiest to keep when your build has a yellow slot that wants physical damage support and high attack.
High-attack opening
The Hyado Arrow opening skill and very high attack add burst to hard content without giving up durability.
Should You Farm or Upgrade It?
Do not plan a new farm for Killer Machine Memory. The Wandering Merchant and Lost Ruins event has ended. Keep a copy you already own if your build uses the ice physical bonus and Hyado Arrow.
Upgrade it only if your active build uses the ice physical damage bonus every day and the yellow slot fit is clean. If your account is moving toward other shrine or event Memories, keep Killer Machine Memory as a sturdy event bridge Memory instead of spending scarce upgrade materials.
Closest Comparison
| Memory | Pick it when | Why |
|---|---|---|
| Killer Machine Memory | You already own Hyado Arrow, ice physical damage +10%, and very high attack | Best fit for physical accounts that can use yellow slots |
| Killer Machine Army Memory | You want a red multiplayer Memory tied to Machine-family content | Different route from the same ended event; keep it if you already cleared that multi |
| Ice Golem | You want ice spell damage and balanced stats from a shrine | Better when your carry is a magic-focused ice build |
| Flame Warrior Memory | You want fire physical damage and high dexterity | Better when your carry uses blue slots and fire physical skills |
| Sky Dragon Memory | You want Dragon family damage, Finish Skara, and very high durability | Better when your carry can use red slots and needs survivability |

FAQ
Is Killer Machine Memory worth farming?
Keep it if you already have it and your build can use a yellow Memory with an opening Hyado Arrow and ice physical damage +10%. The Wandering Merchant event has ended, so do not plan a new farm unless it returns. It is the single-target Killer Machine Memory, not the multiplayer Killer Machine Army Memory.
How is Killer Machine different from Killer Machine Army?
Killer Machine Memory is the single-target yellow Memory that drops from the Machine Ruins stage in the Wandering Merchant and Lost Ruins event. Killer Machine Army Memory is a separate red Memory obtained from the Killer Machine Army multiplayer quest. They have different colors, effects, and acquisition routes.
