WHERE & HOW TO FARM

Where to farm

Ark > Simulation Room.

Simulation Room runs supply materials used to improve Nikke skills. The available sectors and difficulty determine what you can earn, while the battle modifiers shape which squad and buffs are useful. Complete a clearable run, collect its skill materials, then invest in the skills of units you expect to keep using; skill materials are not refunded by a level reset.

GET STARTED

How to farm

Before you go

Unlock Simulation Room through Campaign progression.
Bring a team that can clear an available simulation difficulty.
Identify the Nikke skills you intend to upgrade.

Open Simulation Room and inspect the available sectors and difficulty options.
Read the enemies and modifiers shown for the run.
Choose a difficulty your squad can complete and proceed through the displayed battles.
Select available buffs that support your team’s damage or survival.
Finish the run and claim the skill materials shown in the results.
Open the skill menu for a planned Nikke and spend the appropriate materials.

Farming tips

Use the highest difficulty you can reliably clear; a failed attempt does not help your material plan.
Prioritize core skills on units you use regularly because skill investment is not refunded by a level reset.

Repeat, collect and use

Repeat the available Simulation Room activity as its rewards refresh. Each run provides the materials shown for that run; collect them before leaving the result screen.

Common mistakes

Choosing a difficulty your team cannot finish; step down until you can complete the run.
Ignoring modifiers and selecting buffs blindly; read the current effects and build around them.
Investing skill materials in every unit; focus on your active team because the materials are not returned on reset.
