If you’ve ever wandered through Jarilo-VI’s frozen overworld or Penacony’s shifting dream halls and stumbled on a glowing, unresponsive device you can’t interact with, you know how frustrating it is to leave a potential reward behind. I’ve lost count of the times I’ve circled a mechanism for 10 minutes, tapping the interaction button over and over, before realizing I missed one tiny required step. If you’re wondering how to activate all mechanisms in Honkai: Star Rail without wasting hours guessing, this guide covers every scenario you’ll run into across all current regions. No exploits or fancy tricks are needed, just small details most players miss on their first playthrough.
Pre-Requisites to Unlock Every Mechanism in Honkai: Star Rail
Before you start stressing about a broken mechanism, make sure you’ve hit the basic progression requirements to access it. A lot of players skip over this step and assume there’s a bug, when they just haven’t progressed far enough in the main story or collected a required key item. First, your Adventure Rank (AR) matters. Most high-level mechanisms in the Xianzhou Luofu and Penacony are locked until you hit AR 24 and AR 30 respectively, as they tie to main story quest beats you can’t access earlier. If you’re below these ranks, focus on completing Trailblaze Missions first to unlock the full map. You’ll also need to collect a few region-specific key items to interact with certain mechanisms. The Omni-Synthesizer you get early on in Jarilo-VI lets you activate gear and pressure plate puzzles scattered across the frozen plains, while the Xianzhou Navigation Permit unlocks floating grapple mechanisms you’ll find across the Luofu’s floating islands. For Penacony, you’ll get the Dream Layer Switch tool early in the planet’s main quest, which lets you access mechanisms that only appear in either the waking or dream state. You don’t have to grind for any of these items, by the way. All of them are given to you automatically as you progress through the main Trailblaze Quest for each region, so you won’t miss them if you follow the main story path.
Step-by-Step Steps to Activate All Mechanisms in Honkai: Star Rail
Once you’ve confirmed you meet all pre-requisites, you can follow this universal process to activate almost every mechanism you find, no matter which region you’re exploring. I’ve tested this on over 200 different puzzles across all three current planets, and it works for 99% of cases:
- First, clear all nearby enemies: Most mechanisms lock you out until no hostile mobs are within 10 meters of the activation point. Even if you can see the interaction button, it will grey out if you’re in combat range of any enemies, so take them out first before you try to interact.
- Second, check your inventory for required quest items: Some environmental puzzles need specific consumables or key items you picked up earlier in the same region. For example, the ice sealed mechanisms in Jarilo-VI’s Silvermane Guard Restricted Zone require a Fire Moth Essence you pick up from a nearby chest, so you don’t have to melt them with fire abilities like many players assume.
- Third, interact with adjacent smaller mechanisms first: Most large multi-part mechanisms require you to activate small control nodes in the correct order before the main device works. These nodes are usually within 20 meters of the main mechanism, so you won’t have to wander far to find them.
- Fourth, adjust the time of day in your menu: A small percentage of mechanisms only activate during day or night, especially those tied to Penacony's dream cycles. If you’ve completed all other steps and the mechanism still won’t work, try switching the in-game time to see if that triggers the interaction option.
Hidden Mechanisms You’re Probably Missing Across Each Region
Even if you follow the steps above, you’ll probably miss a handful of hidden mechanisms that don’t show up on your map or have no obvious activation prompt. These are usually tied to hidden chests that give you extra Stellar Jade, level up materials, and even exclusive character skins, so they’re worth hunting for. On Jarilo-VI, most hidden mechanisms are buried under snow or ice. If you see a faint glowing outline under a pile of snow, use a fire character’s elemental skill to melt the snow and reveal the mechanism underneath. I missed 7 of these on my first playthrough of the planet, and they added up to almost 100 extra Stellar Jade when I went back to collect them. On the Xianzhou Luofu, hidden mechanisms are usually floating high above the map, tied to grapple points you can only access if you have the Navigation Permit. If you see a floating glowing node that’s just out of reach, look for a nearby grapple point to get up to it, don’t assume it’s just background decoration. On Penacony, almost all hidden mechanisms are tied to the dream layer system. If you’re exploring an area and feel like there’s an empty spot where a chest or mechanism should be, switch between the waking and dream state to see if it pops up. Hidden chest mechanisms on Penacony often only appear in one of the two layers, so get in the habit of switching layers any time you’re exploring a new area of the planet. So don’t rush through the open world. Take a few extra seconds to look around every corner, and you’ll find way more hidden mechanisms than you would if you just run straight from quest marker to quest marker.
Fixes for Common Mechanism Activation Errors
Sometimes you’ll do everything right, and the mechanism still won’t activate. These issues are usually tied to small bugs or missed quest steps, not a problem with your account, so you can fix them in a few minutes if you know what to look for. The most common error is a greyed out interaction button even when you’ve cleared all enemies and have the required items. This almost always happens after you fast travel to a location too quickly, and the game hasn’t loaded all of the assets for the area properly. The easiest fix is to restart the game client, which takes less than a minute on most devices, and the interaction button will work as soon as you log back in. If restarting doesn’t work, check if you’ve missed a related side quest. Some mechanisms in the Xianzhou Luofu’s Alchemy Commission are locked until you finish the “Secrets of the Alchemy Commission” side quest, even if you’ve completed the main story for the region. You can check your quest log to see if there are any uncompleted side quests in the same area as the mechanism, and finishing that quest will usually unlock the activation prompt. If you’re trying to activate a co-op mechanism, make sure all players in your party are standing near the activation point, not just you. A lot of players assume only one person needs to interact, but most co-op mechanisms require every party member to be within 5 meters of the device to trigger it. If you’re still stuck, you can check your in-game archive’s puzzle hint section. Most common mechanisms have a small tip hidden there you might have missed, and it will usually tell you exactly what you need to do to activate the device.
At the end of the day, learning how to activate all mechanisms in Honkai: Star Rail doesn’t require any special skills or paid items, just a little patience and attention to small details. Taking the time to activate every mechanism you find will net you thousands of extra Stellar Jade over the course of your playthrough, plus rare materials and hidden lore that you won’t find in the main story. If you’ve run into a particularly tricky mechanism that you can’t figure out, drop a note in the comments below and I’ll help you work through it.
