How to Modify Equipment in Nikke: A Complete Guide

Modifying equipment in Goddess of Victory: Nikke is one of the game's deeper progression systems — and one that confuses a lot of players who rush past it early on. Done right, it can meaningfully increase your Nikkes' combat power. Done poorly, it burns through resources with little to show for it. Here's how the system actually works.

What "Modifying Equipment" Means in Nikke

In Nikke, equipment modification refers to upgrading the stat lines on gear pieces your Nikkes wear. Each Nikke can be equipped with multiple gear slots — including parts like helmets, gloves, chest pieces, and boots — and each piece of gear carries base stats plus potential bonus attributes.

Modification lets you reroll or enhance those bonus attributes, pushing a piece of gear beyond its base values. This is different from simply leveling up a Nikke or ascending her rarity. Equipment modification is specifically about the gear itself, not the character.

Where to Access the Equipment Modification Menu 🎮

You'll find the modification system inside the Outpost menu, under the equipment management section. The path is:

  1. Open the Outpost
  2. Select a Nikke
  3. Tap on an equipped gear piece
  4. Choose the Modify or Enhance option

Some features within this system unlock at specific Commander levels, so if you don't see all options immediately, progression will open them up.

Understanding Gear Grades and Why They Matter

Not all gear is worth modifying. Nikke uses a gear grade system — typically ranging from basic gray/white tier up to higher colored tiers like blue, purple, and gold (SR/SSR-equivalent grades depending on the game's current naming conventions).

Higher-grade gear has:

  • More bonus attribute slots
  • Higher stat ceilings
  • Greater returns on modification investment

Modifying low-grade gear is generally wasteful because that gear will be replaced as you progress. The community consensus — and the game's own design logic — suggests holding off on heavy modification investment until you're working with high-grade equipment you plan to keep for a while.

How the Modification Process Works

When you modify a piece of equipment, you're targeting its bonus stat lines (sometimes called sub-stats or bonus options). Here's the general mechanic:

  • Each gear piece has a set number of bonus attribute slots determined by its grade
  • You spend modification materials (typically Battle Data Sets, Molds, or similar resources) to attempt to change or enhance those bonus stats
  • The result can improve, stay the same, or give you a different stat than what was there before — depending on the specific modification type you use

There are generally two kinds of modification actions:

ActionWhat It Does
EnhanceIncreases the numerical value of an existing bonus stat
Reroll / ResetReplaces a bonus stat with a randomly selected alternative

This distinction is critical. Enhancing is more predictable — you're investing in what's already there. Rerolling introduces randomness and can help or hurt, depending on what you get.

What Stats Are Worth Targeting

The value of a particular stat depends heavily on which Nikke you're gearing and what role she plays in your squad. However, some general principles hold:

  • ATK (Attack) bonuses are broadly useful for DPS-oriented Nikkes
  • Max HP and DEF matter more for support or tank roles
  • Hit Rate and Critical Rate are situationally valuable depending on the Nikke's kit
  • Elemental resistance stats tend to be lower priority for general content

The optimal stat combination for a given Nikke is tied to her burst type, weapon class, and the content you're running — which is why the same gear build rarely works identically across all characters.

Materials Required for Modification

Modification consumes specific resources that are not infinitely available, which makes prioritization important. Common resource types involved include:

  • Battle Data Sets (tiered by level range)
  • Molds for crafting or upgrading gear
  • Credits (the basic in-game currency)

These materials come primarily from Simulation Room runs, Story mode stages, and various game modes that unlock over time. Because they're finite on a daily/weekly basis, how you allocate them across your roster matters.

The Spectrum of How Players Approach This System

Players approach equipment modification very differently depending on where they are in the game:

  • Early-game players are often better served prioritizing Nikke leveling and story progression over heavy gear modification
  • Mid-game players typically start selectively modifying gear on their main DPS or core team members
  • Late-game and endgame players engage deeply with rerolling bonus stats on high-grade gear, chasing near-optimal stat combinations for content like Tribe Tower floors, Raids, and PvP (Ark) modes

The returns on modification investment scale significantly with game progression — what makes sense at Commander level 100 looks completely different from what's optimal at level 200+.

Variables That Determine Your Best Approach

Several factors shape how and when modification makes sense for your account:

  • Your current Commander level and what content you can access
  • Which Nikkes you're actively building and their roles
  • How far you are into your main team's gear grade — are the pieces you're modifying going to last?
  • Your daily resource income — how many modification materials are you generating?
  • The game mode you're prioritizing — PvP has different optimization targets than PvE raids

The modification system rewards players who have a clear picture of their roster goals and resource flow. Without that context, even technically correct modifications can end up being poor investments for a specific account's situation.
