Crimson: Twin Butterflies

Overview

Crimson: Twin Butterflies is one of the twelve Cartridge sets in Neverness to Everness. Cartridges are the named, themed pieces of Console Equipment that grant set bonuses when two or four pieces from the same set are placed on a character's grid. Unlike generic Modules, which only contribute raw stats, Cartridges are the part of the loadout that actually shapes a character's playstyle through their 2-piece and 4-piece effects.

Crimson: Twin Butterflies is a Cartridge set built around amplifying Incantation damage. The 2-piece bonus delivers a flat Incantation damage increase, while the 4-piece grows the wearer's ATK whenever any teammate lands Incantation hits on nearby enemies. Because the stacking effect remains active off-field, the set rewards rotation-heavy compositions where the wearer fires off a strong burst, swaps out, and continues to passively benefit from Incantation pressure applied by allies.

Set Bonuses

Like other Cartridges in the game, Crimson: Twin Butterflies unlocks an Epic-tier bonus when two pieces of the set are equipped together, and a stronger Legendary-tier bonus when the wearer fields the full four-piece set. The 2-piece is always active. The 4-piece carries the conditional or stacking effect that defines the set.

Main Stat Options

The main stat on a Cartridge is fixed when the piece drops and is rolled from the same general pool used by every Cartridge set. Higher cell-cost pieces tend to roll the stronger main stats, and main stat values scale linearly between Level 1 and the maximum Level 20 enhancement. The full table below shows the full level-1 to level-20 ranges for every main stat type that Crimson: Twin Butterflies can roll.

Sub-Stat Options

Each Cartridge piece rolls up to four sub-stats that are independent of the main stat. Sub-stats can land on any of the following types, and roll values are shared across the cartridge pool. Higher rarity pieces gain more sub-stat slots and stronger initial roll ranges.

Rarity Tiers

Crimson: Twin Butterflies drops in three rarity tiers. Higher rarity Cartridges roll higher base main-stat values, more sub-stat slots, and reach higher final values when fully enhanced. The intended endgame set is the 5-star (S-Rank) version, with 4-star pieces serving as a strong intermediate option and 3-star pieces filling the slot during early Console builds.

How to Obtain

Crimson: Twin Butterflies is farmed alongside the rest of the Cartridge pool through the Rabbit Hole activity, the regular boss and enemy farming mode used to acquire Console Equipment. Runs cost Stamina (the recharging energy used for repeatable rewards), and the player claims drops at the end of each run rather than mid-fight. Specific Cartridge sets are tied to specific Rabbit Hole domains, so farming the right domain is the most efficient way to chase a complete four-piece loadout for this cartridge.

Like other Console Equipment drops, the rolls on each piece are randomized when it drops. Multiple farming sessions are normally required to land a four-piece set with desirable main stats and sub-stat lines for the intended carry. Stockpiling lower-rarity pieces of the same set is also useful, since they can be consumed as enhancement material to push the keeper pieces to Level 20.

Recommended Use

Crimson: Twin Butterflies is built for one general role: Off-field Incantation amplifier. The 2-piece bonus is always live, while the 4-piece is the part of the set that decides whether this cartridge is worth a slot on a given character. Players building toward this set should plan their team around the conditions written into the 4-piece text, rather than treating it as a generic stat boost.

Like all Cartridge picks, the choice is also driven by what other sets are available to the wearer. If a more specialized set already covers the character's element or role better than Crimson: Twin Butterflies does, that set takes priority; if not, the bonuses listed above offer one of the strongest options in the current pool.

Compatible Geometries

A Cartridge can only be installed in a Console panel whose geometry matches one of its compatible shapes. The list below names every panel shape that accepts a piece from the CRIMSON: TWIN BUTTERFLIES set; any other shape on the Console grid rejects the piece during equip.

Set Classification

The Console categorizes Cartridges by physical set type and exposes a single optimization cap that defines how far a piece can be enhanced before its main stat plateaus.

When planning a four-piece equip, pre-check the Console panel layout for the wearer to confirm that enough matching geometry slots exist; mismatches are the most common reason a four-piece bonus fails to activate even with all four pieces in inventory.
