In Arknights Endfield, several items serve environmental, lore, or progression-related purposes rather than direct combat value. Mr Rammu is one such item. While many players initially assume it is decorative or unfinished content, Mr Rammu actually has a valid in-world placement condition that must be met for it to function correctly. This guide explains exactly where, when, and how to use Mr Rammu, with full clarity and no guesswork.

What is Mr Rammu in Arknights Endfield
Mr Rammu is a special display item tied to world interaction rather than inventory stats or character upgrades. It exists primarily to interact with a specific structure inside the Dijiang facility, reinforcing Endfield’s emphasis on environmental storytelling and location-based mechanics.

Unlike crafting materials or relics, Mr Rammu cannot be placed freely. Attempting to deploy it in any random location will result in no interaction prompt, which often leads players to believe the item is bugged. In reality, it has a single valid placement point.
Dijiang and the Tower of Trails explained
Dijiang is a late-early to mid-game industrial region, unlocked through the main storyline. It functions as a large operational facility containing research structures, vertical traversal routes, and unique interactive objects.
Inside Dijiang lies the Tower of Trails, a landmark structure designed to accept specific display or trial-related items. Mr Rammu is explicitly designed for this tower, and nowhere else in the game world.

How to use Mr Rammu display item in Arknights Endfield
Step 1: Unlock Dijiang
You must progress the main story until Dijiang becomes accessible. This unlock is non-optional and tied to core narrative advancement. If Dijiang is not visible on your world map, Mr Rammu cannot be used yet.

Step 2: Travel to the Dijiang facility
Once unlocked, fast travel or manually traverse to the Dijiang region, then enter the main facility area. This is the central hub where most structural interactions occur.

Step 3: Locate the Tower of Trails
Inside the facility, identify the Tower of Trails, a tall, distinct structure designed for item interaction. It stands out visually and is not part of the regular terrain flow, making it easier to spot once you’re nearby.

Step 4: Place Mr Rammu
Approach the correct interaction point on the Tower of Trails. When positioned correctly, the placement prompt will appear automatically. Confirm the interaction to place Mr Rammu, completing its intended use.

Common mistakes players make with Mr Rammu
| Mistake | Why it happens |
|---|---|
| Trying to place it in the open world | Mr Rammu is location-locked |
| Assuming it is decorative only | Its function is environmental |
| Thinking it is bugged | Placement conditions are strict |
| Missing the Tower of Trails | Structure is not marked early |
If you do not see a prompt, you are not at the correct location. There is no alternate placement and no workaround.
Does Mr Rammu give rewards
Mr Rammu does not provide direct combat rewards, stats, or materials. Its value lies in world completion, interaction progression, and environmental triggers. These types of items are common in Endfield and often contribute to future unlock conditions or lore-based progression, even if the immediate reward is subtle.
What are display items in Arknights Endfield
