RULES

Unlock checklist

SECRET REQUIREMENTS
01

Neon Wraith: use Nox on the Forgotten Cove.

02

Defeat the Abyssal Tide Beast, reach combo 50+, take at most 10 hits, and open no chests.

03

Global Kinetic Trail: after Neon Wraith is unlocked, survive 5 minutes with him to unlock Kinetic Trail for other heroes.

04

Runic Mime: use Neon Wraith in the Forgotten Dungeon.

05

Defeat the Dungeon Lord, reach combo 35+, take no hits, and open no chests.

06

Vesper: on Stage 12, die at least once and then score 3,000 direct Soul Orb kills after the first death.

07

Iris: on Stage 11 / Arcane Rift, defeat the Rift Heart with combo 75+, take at most 3 hits, and open no chests. The trial works solo.

IMPORTANT. Unlocking a character and making that character's weapon available to other heroes are separate goals. The wiki lists both requirements to avoid confusion.
CRITICAL

Rules that are easy to confuse.

DO NOT MERGE THESE GOALS

Vesper — Soul Orb secret

In Stage 12, the run must record at least one player death. After that first death, 3,000 enemies must be defeated directly by Soul Orb. Any character can satisfy the requirement, and only direct finishing blows from that weapon after the first death count.

150,000 against one

The 150,000-kill achievement still requires 150,000 eliminations in a single run; it is independent from Vesper's unlock requirement.
