Citadel Biome Guide: Traps, Items, Badges

Card No. 06·30144 · Updated · Standard formula, shown below

This guide explains how to survive and thrive in the Citadel biome in Peak, covering every trap you may encounter, the items worth looting, and all badges you can earn there. You’ll learn the exact mechanics of each hazard, the best strategies for looting safely, and what it takes to unlock every badge in this end‑game area.

Background: What Is the Citadel Biome?

The Citadel is one of the hardest biomes in Peak, introduced in the late‑game update that expanded the map beyond the earlier forest and desert zones. It’s a massive, crumbling fortress complex filled with high‑tier loot but also the most dangerous traps in the game. Unlike earlier biomes, the Citadel is designed for players who have already maxed out their gear and are looking for the final challenge before the endgame boss. Its layout is a maze of corridors, towers, and underground vaults, each section guarded by a different type of trap.

The biome’s difficulty comes from the combination of environmental hazards and enemy NPCs that patrol the halls. You’ll need to learn the trap patterns by heart, because a single misstep can cost you your run. The rewards, however, are worth it: the Citadel is the only place where you can find the legendary Vault Key and the Chrono Shard, both essential for crafting the best equipment in the game.

All Traps in the Citadel and How to Avoid Them

There are eight distinct traps in the Citadel, each with a unique trigger and counter. Knowing them is the difference between a successful raid and a quick respawn.

  • Floor Spikes – These pop up from the ground in a set pattern. They activate when you step on a pressure plate, but the pattern is always the same: the spikes rise in a wave from the plate outward. To avoid them, step on the plate and immediately back away, or use a ranged weapon to trigger it from a distance.
  • Wall Arrows – Fired from hidden slots in the walls when you cross a tripwire. The tripwire is visible if you look closely – a thin line at ankle height. Crouch and walk over it, or destroy the tripwire with a thrown knife.
  • Ceiling Boulder – A large boulder drops from the ceiling when you step on a specific tile. The tile is slightly darker than the others. You can spot it by the small cracks around its edges. Simply walk around it.
  • Poison Gas Vents – These emit a cloud of gas that damages you over time. The vents activate when you enter a room, but they follow a cycle: 5 seconds on, 5 seconds off. Time your movement between the cycles.
  • Flame Jets – Similar to gas vents but they shoot a stream of fire. They are always on a timer, and the flame reaches about 3 blocks forward. Wait for the burst to end, then run past.
  • Pendulum Blades – Large swinging blades that cover a wide arc. They are easy to see but hard to time. Wait for the blade to swing away, then run through the gap. The timing is consistent, so you can count the seconds.
  • Collapsing Floor – A section of the floor that gives way when you stand on it, dropping you into a pit with spikes. The floor looks slightly different – it has small cracks. You can jump over it, or use a grappling hook to cross.
  • Electric Grid – A floor panel that zaps you with electricity when you stand on it. It’s activated by a switch on the wall. You can disable the switch with a ranged attack, or simply walk around the grid.

The key to surviving all traps is to move slowly and observe. Most traps have a visual tell – a crack, a tripwire, or a darker tile. If you rush, you’ll trigger them. Also, always carry a few Repair Kits because some traps can damage your armor.

Items Found in the Citadel: What to Grab and What to Skip

The Citadel is a treasure trove, but not everything is worth the risk. Here’s a breakdown of the items you’ll find and their value.

  • Vault Key – This is the most valuable item. It opens the central vault in the Citadel, which contains a guaranteed legendary weapon. It’s found in a locked chest in the east tower, guarded by a mini‑boss. Always grab it if you see it.
  • Chrono Shard – A rare crafting material used for the best armor upgrades. It drops from the Chrono Golem boss, which appears in the underground arena. It’s worth fighting for, but only if you have good gear.
  • Ancient Relics – These are small statues that sell for a high price to vendors. They’re common in the Citadel, but they take up inventory space. Grab them if you have room, but don’t prioritize them over healing items.
  • Healing Herbs – Found in the garden areas. They restore 50 HP, which is crucial during long runs. Always stock up.
  • Lockpicks – Used to open the many locked chests. You’ll find them on enemies and in breakable pots. Carry at least 5 at all times.
  • Trapspring – A consumable that disarms one trap for 10 seconds. It’s rare but extremely useful for getting through tight spots. Use it when you’re cornered by multiple traps.

Skip items like Rusty Nails and Broken Gears – they’re junk and only take up space. Also, avoid picking up Cursed Idols unless you have a Cleansing Charm, because they reduce your max HP by 10% until you leave the biome.

All Badges in the Citadel and How to Earn Them

Badges are achievements that give you cosmetic rewards and bragging rights. The Citadel has five unique badges.

  • Ghost Runner – Complete the Citadel without triggering a single trap. This is the hardest badge. You need to memorize all trap locations and use the Trapspring item to disable them. It’s possible, but it takes practice.
  • Vault Raider – Open the central vault 10 times. This requires farming the Vault Key, which means killing the mini‑boss in the east tower repeatedly. It’s a grind, but doable.
  • Chrono Breaker – Defeat the Chrono Golem without taking any damage. The Golem has a pattern of attacks – you can dodge them all if you stay at mid‑range and roll at the right time. It’s a test of your combat skills.
  • Scavenger – Collect 100 Ancient Relics in one run. This means you need to explore every corner and open every chest. It’s easier with a group, but solo players can do it if they move fast.
  • Trapmaster – Disarm 50 traps using the Trapspring item. You’ll need to craft or find a lot of them. The best way is to farm the garden area for herbs and sell them to buy Trapsprings from the vendor.

Each badge gives a unique banner and a title you can display on your profile. The Ghost Runner badge is the most prestigious because it requires perfect play.

How to Choose Your Loadout for the Citadel

Your loadout can make or break your run. Here are the essential items to bring.

  • Weapon: A ranged weapon is a must for triggering traps from a safe distance. The Crossbow is the best choice because it has high damage and can be fired quickly. A melee weapon is secondary – use it only for enemies.
  • Armor: Light armor is better for dodging traps, but if you’re not confident, heavy armor will let you survive a few hits. The trade‑off is speed. For the Citadel, speed is more valuable because most traps are avoidable.
  • Consumables: Carry at least 10 Healing Herbs, 5 Trapsprings, and 3 Antidotes (for poison gas). You can buy these from the vendor at the entrance, but they’re expensive, so stock up before you enter.
  • Tools: A grappling hook is essential for crossing gaps and avoiding floor traps. Lockpicks are also necessary for the many locked chests.

The best strategy is to go in with a full inventory of healing items and a few Trapsprings. You can always leave and come back if you run out, but the biome resets, so you’ll have to re‑explore.

Common Mistakes and How to Avoid Them

Even experienced players make these mistakes in the Citadel. Here’s what to watch out for.

  • Rushing through corridors – This is the #1 cause of trap deaths. Always walk slowly and look at the floor and walls before proceeding.
  • Ignoring the minimap – The minimap shows trap locations as red dots once you’ve discovered them. Use it to plan your route.
  • Not using the environment – You can throw rocks or use arrows to trigger traps from a distance. This is safer than walking into them.
  • Overloading on loot – If you’re carrying too much, you move slower, making it harder to dodge traps. Only pick up items you really need.
  • Fighting enemies near traps – Enemies can push you into traps. Always lure them away from trap zones before fighting.

Another common misconception is that the Vault Key is a one‑time use. In fact, it’s a key that you can use multiple times, but it breaks after 3 uses. So don’t use it on the first vault you see – save it for the central vault that has the best loot.

Frequently Asked Questions

Can I enter the Citadel at any level? Technically yes, but you’ll likely die. The enemies are level 50+, and the traps deal 100+ damage. It’s recommended to be at least level 45 with good gear.

Do traps reset after I leave the biome? Yes, all traps reset when you leave and re‑enter. This means you can’t clear a path and come back – you have to re‑navigate every time.

Is the Ghost Runner badge possible with a group? Yes, but it’s harder because traps can be triggered by other players. It’s easier solo, but if you coordinate well, a group can do it by having one player scout ahead.

What’s the best way to farm the Chrono Shard? The Chrono Golem has a 25% drop rate for the shard. You can kill it multiple times in one run if you don’t leave the biome – it respawns after 10 minutes. So you can farm it by staying in the underground arena.

Are there any hidden areas in the Citadel? Yes, there’s a secret room behind the waterfall in the garden area. It contains a chest with a Legendary Bow. To open it, you need to shoot the three hidden switches on the walls.

Do badges carry over to new game+? Yes, badges are permanent once earned. You can display them in any playthrough.
