This article explains what the Red Serpent House Bell is in Phantom Blade Zero: a key item used to unlock a hidden boss fight and a special outfit. You obtain it by completing a side quest chain in the Red Serpent House area, then ring it at the sealed shrine to trigger the encounter.
Formula
The calculator above is a pace and speed converter, not part of the game guide. It uses two standard formulas:
- Pace = finish time (minutes) ÷ distance (km), giving min/km.
- Speed = distance (km) ÷ (finish time ÷ 60), giving km/h.
Variables: t = time in minutes, d = distance in kilometers. The output is rounded to two decimals.
Worked Example
Using the default values (t = 50 min, d = 10 km):
- Pace = 50 ÷ 10 = 5.00 min/km
- Speed = 10 ÷ (50 ÷ 60) = 10 ÷ 0.8333 = 12.00 km/h
The calculator returns 5.00 min/km and 12.00 km/h.
Where the Red Serpent House Bell Fits in Phantom Blade Zero
Phantom Blade Zero is an action RPG by S-GAME, set in a fictional martial-arts world inspired by Chinese wuxia. The Red Serpent House is a faction you encounter mid-game, known for poison techniques and hidden rituals. The bell is a quest item tied to that faction’s lore — it is not a weapon or consumable, but a key that opens a locked encounter.
Players often miss it because the quest chain is optional and requires backtracking after a certain story beat. The bell itself is a small bronze handbell with a red serpent emblem, and using it at the right shrine triggers a boss fight that rewards a unique outfit and a skill tome.
How to Get the Red Serpent House Bell
The acquisition involves a multi-step side quest. Follow these steps in order:
- Reach the Red Serpent House compound (around chapter 3, after the “Poisoned Blade� main quest).
- Talk to the NPC “Old Wei� near the east gate — he mentions a stolen ceremonial bell.
- Find the thief’s hideout in the sewers beneath the compound; defeat the mini-boss there.
- Return the bell to Old Wei, but do NOT leave the area — he will ask you to ring it at the sealed shrine behind the main hall.
- Walk to the shrine (marked on your map after step 4) and interact with it while the bell is in your inventory.
If you miss talking to Old Wei before finishing chapter 3, the quest becomes unavailable in that playthrough. New Game+ allows you to redo it.
What the Bell Actually Does (and What It Doesn’t)
Ringing the bell at the shrine summons the “Red Serpent Guardian,� a mid-tier boss with poison attacks. Defeating it drops:
- The “Crimson Ritual� outfit (cosmetic only, no stats).
- The “Serpent’s Grace� skill tome, which unlocks a new dodge-counter move.
- A small amount of upgrade materials.
The bell has no other uses — it cannot be sold, equipped, or used in combat. Some players mistakenly think it opens a secret door in the compound; it does not. The only interaction point is the shrine.
Common Problems and Misconceptions
Three issues come up often in player discussions:
- Bell not appearing in inventory: This usually means you didn’t talk to Old Wei after the sewer fight. The bell is a quest item, so it doesn’t show in the regular inventory tab — check the “Key Items� section.
- Shrine not interactive: The shrine only activates after you complete the main quest “The Serpent’s Wake.� If you try earlier, nothing happens. Progress the story, then return.
- Bell used up? No, the bell remains in your inventory after the boss fight. It’s a keepsake item with no further function.
Another misconception is that the bell is needed for the true ending. It is not — the true ending requires a separate choice in the final chapter. The bell is purely optional content.
Is the Red Serpent House Bell Worth Getting?
For completionists, yes — the outfit and skill tome are unique. The skill tome, in particular, is useful for players who rely on parry timing, as the new move gives a larger window after a successful dodge. However, if you’re only interested in the main story, you can skip this quest without losing any critical progression. The boss fight is moderately difficult (recommended level 35-40), and the reward is not game-breaking.
Compared to other optional bosses in the game, the Red Serpent Guardian is easier than the hidden dragon boss but harder than the standard elite enemies. The fight teaches you to watch for telegraphed poison sprays, which is good practice for later areas.
Frequently Asked Questions
Can I get the bell after finishing the game?
No, not in the same playthrough. The quest is time-locked to chapter 3. However, New Game+ lets you replay the entire game with your previous gear, so you can pick it up there. There is no way to trigger it in the post-game free roam.
Does the bell affect the ending?
No. The bell only unlocks an optional boss and its rewards. The ending is determined by a separate decision in the final chapter, which is unrelated to the Red Serpent House quest chain.
What level should I be for the boss fight?
Around level 35-40 is comfortable. The boss has poison attacks that can stack, so bring antidote items and consider equipping poison-resistant gear if you have it. If you’re underleveled, the fight is still possible but will take longer.
Is the bell a one-time use item?
No, it is a permanent key item. You can ring the shrine multiple times, but the boss only spawns once. After the fight, the shrine becomes inactive.
Can I sell or drop the bell?
No, key items cannot be sold or dropped. It will stay in your inventory for the rest of the playthrough.
What if I missed Old Wei’s dialogue?
If you progressed past chapter 3 without talking to him, the quest is locked. You’ll need to start a New Game+ or reload an earlier save. There is no other way to obtain the bell in that save file.
Final Tips for the Red Serpent House Quest
Before you start, save at the nearest shrine. The sewer mini-boss can be tough if you’re underleveled, and dying mid-quest may reset some NPC positions. Also, explore the compound thoroughly — there are two other hidden chests in the area that contain upgrade materials, but they are not marked on the map. The bell quest is a good example of Phantom Blade Zero’s hidden content: it rewards exploration but doesn’t punish you for skipping it.
