Epic Battle 2026 Q3 — Folhvita, the Frostborn Princess

Folhvita, the Frostborn Princess — campaign key visual

The second Epic Battle of the season. Face Folhvita, the Frostborn Princess — an ice-element boss who shelters behind a living Butterfly Wall, where frost magic freezes the unready and a single hex can spell instant doom. Cut down her sisters across five escalating stages — and the final one-time Folhvita ZERO — to gather Folhvita’s Wings, exchange them in a limited-time supply shop, and — if you’re strong or patient enough — add Folhvita herself to your roster as a playable UR or SSR character.

Campaign Window

Runs until July 6, 2026 — 23:59 (server time). After that, a 3-day grace window keeps the supply exchange open so you can still spend leftover Wings — but new battles stop counting toward the leaderboard after the window closes.

How to Access

The campaign runs at the Blackwater Correctional Facility — the institution that holds Folhvita’s challenge while the event is live. You can reach it directly from the shortcut on Home, or browse for it on your Institution Tab.

The institution is visible to everyone during the campaign, but to enter it you’ll need:

Steelbreaker Mercenary Union at Lv 5
Starseeker Anti-Air Command at Lv 5
Plus a one-time 10,000 gold unlock payment

Stage Brief

Five repeatable difficulty levels against Folhvita, plus a final one-time showdown. Every fight unfolds in two phases: a lone frost sentinel, then the Butterfly Wall — a swarm of butterflies shielding the Princess. Each stage needs a full 6-hero party. Expect heavy frostbite, paralysis, and stuns throughout — bring cleanses or healing-over-time so a frozen hero doesn’t become a lost one. Higher levels drop more Wings per clear but demand real party strength.

Stage	Repeatable	Notes
Lv.10	Yes	Warm-up. Drops a small handful of Wings per clear.
Lv.50	Yes	Scouting stage. Good check of your element and defense setup.
Lv.100	Yes	Wing efficiency sweet spot — daily farming target once you can clear it reliably.
Lv.150	Yes	Mid-campaign wall. Rewards jump noticeably when you can clear it.
Lv.200	Yes	Top repeatable stage. Highest Wing drop per clear.
Folhvita ZERO (Lv.200)	One-time	The campaign’s final showdown. Clear it once and you are guaranteed a Folhvita’s Prismatic Wing — the only way to redeem the UR Folhvita summon in the shop.

Unlike a single-stage boss, Folhvita’s challenge unfolds in two waves: clear the opening assault, then face the Butterfly Wall shielding the Princess.

Folhvita battle — wave 1, the butterfly assault — Wave 1 — Folhvita opens with a storm of butterflies.

Folhvita battle — wave 2, the Butterfly Wall formation — Wave 2 — the Butterfly Wall guarding the Princess.

Supply Exchange

The institution’s supply counter opens the Folhvita exchange. Caps listed are per-account, per-campaign.

Cost	You get	Cap
Folhvita’s Prismatic Wing × 1	Folhvita (UR) Summon	1
Folhvita’s Wing × 2,000	Folhvita (SSR) Summon	10
Folhvita’s Wing × 10,000	UR Ticket × 1	1
Folhvita’s Wing × 1,000	SSR Ticket × 1	10
Folhvita’s Wing × 100	Premium Ticket × 1	100
Folhvita’s Wing × 10	Draw Card Ticket × 1	1,500
Folhvita’s Wing × 1	Gold Coin × 1,000	20,000

Two ways to walk away with a Folhvita card: clear Folhvita ZERO for the guaranteed Prismatic Wing (redeemable for the UR summon), or spend 2,000 Wings per SSR summon in the shop. Folhvita ZERO also only consumes 1 energy to challenge, so the barrier to the UR path is skill, not stamina.

SSR Folhvita card reveal — SSR Folhvita — 2,000 Wings in the shop.

UR Folhvita card reveal — UR Folhvita — clear Folhvita ZERO for the Prismatic Wing.

★ MND Stat Guarantee

When you obtain a Folhvita playable card from this campaign, its MND stat is guaranteed to roll at or above a minimum threshold — you’ll never get a weak-MND Folhvita.

Tips

Bring Fire

Folhvita is Ice-element. Fire attackers hit hardest against her and her butterflies. If you’ve been saving your Fire SSRs, this is their campaign.

Break the Butterfly Wall first

One butterfly weaves a gossamer ward that cuts all damage — to the other butterflies and Folhvita herself — down to 1. Kill that warden first to break it. Bring an Archer to reach the rear, where it hides.

Beware the Death Curse

One butterfly hexes a random hero with an instant death-curse that ignores all defenses. The cast can be interrupted, though — stun or burst down the curse-weaver before it lands.

Then burst the Princess to end it

Once the ward is down, focus Folhvita herself — defeating her ends the battle instantly, even if butterflies are still fluttering. You don’t need to clear the whole swarm; you need to reach the Princess.

Farm the middle stages daily

Lv.100–150 gives the best Wing-per-battle return once you can clear them on autopilot. Run them daily and save your Lv.200 / Folhvita ZERO pushes for when your strongest party is fully deployed.

Leaderboard

★ Spend Freely — Rank is Lifetime

Your leaderboard position is based on the total Wings you have earned during the campaign — not your current balance. Spending Wings at the supply shop will never reduce your rank. Farm what you need, spend what you want — every Wing you earn counts toward your ranking for good.

The Top 300 players on the leaderboard will receive an exclusive Folhvita Archon Skill.
