Higan Eruthyll Codes: Active and Expired (June 2026)
Last checked June 20, 2026 (UTC)
Higan Eruthyll codes turn up around updates and anniversary events, and BILIBILI doesn't make a big deal of them, so I keep the live ones rounded up here. We refresh this whenever new ones drop.
Higan: Eruthyll codes are the alphanumeric strings BILIBILI releases on the official Higan Eruthyll channels and during update livestreams for free Crystals (the premium currency), summon tickets, Gold, EXP materials, and character upgrade items. Crystals are what you spend on the gacha that recruits new Dolls, the playable 3D characters. Summon tickets pull straight away. Gold and EXP materials feed the leveling track that keeps your roster climbing. None of it goes to waste.
Quick tip. hold your Crystals and summon tickets for the limited Doll banners instead of the standard pool. The limited Dolls are the ones that carry your team synergy through the harder stages, while the standard pool just keeps recycling characters you can pull whenever you like.
New ones show up during major content updates, anniversary events, and developer livestreams. It's a pretty standard gacha rhythm, so don't expect a fresh code every week. You redeem in game through the settings or profile menu, they're case sensitive, and your account needs to be past the prologue.
- Redeem in game through the settings or profile menu.
- Most codes expire within 14 to 30 days of release.
- Each code is single use per account.
- They're case sensitive, so use the Copy button to dodge typos.
- I'd save the Crystals and tickets from Higan Eruthyll codes for roster building.

How to redeem Higan: Eruthyll codes
Redemption is all in client, through the settings or profile menu. There's no separate website for it. Whatever you redeem lands in your in game mailbox.
- Open Higan Eruthyll and tap your profile or the settings icon.
- Find the redemption or exchange code option.
- Type or paste the code in exactly as shown, since they're case sensitive.
- Confirm to redeem.
- Pop open your in game mailbox to claim the Crystals, tickets, and materials.
If you can't find the redemption option, finish the early prologue first. The code field only unlocks once you've cleared the tutorial stretch of the campaign.
Higan: Eruthyll codes FAQ
What are Crystals used for?
Crystals are the premium currency for the gacha that recruits new Dolls, the playable 3D characters. They're what gates how fast your roster grows, so when Higan Eruthyll codes drop Crystals, those are the ones collection-focused players care about most.
Should I save for limited Doll banners?
Yeah, I would. The limited Dolls define your team synergy in the harder stages and event content, and they only show up during their banner window. The standard pool keeps recycling characters you can pull anytime, so bank your Crystals and tickets for the limited ones.
Is Higan Eruthyll available globally?
It is. There's a global release published by BILIBILI, and the English version is the one most international players use. Codes from the official global channels apply to the global server.
Why does my code keep failing?
Three usual causes: it expired, you already used it on this account, or a capital letter is off. The codes are case sensitive, so copy them rather than typing them out by hand.
Do codes work on the PC client?
They do. The PC client shares your account with mobile, so redeem through the settings menu on whichever one you're on and the rewards drop into the same mailbox.
How long do mailbox rewards stay claimable?
About thirty days for most code rewards. Open your in game mailbox and claim everything before the timer runs out, especially the Crystals, since you'll want those for the current banner.
