Arknights Material Planner

Enter how many materials you need and what you already own. The planner shows what you still lack, including lower-tier materials required for crafting—same logic as the AN-EN-Tags material inventory tool.

How to use the material inventory calculator

Track what you still need after crafting lower tiers in the Workshop.

  1. In each row, enter Need (how many you want) and Have (what is in your warehouse). Still need shows the gap, including materials required to craft higher tiers in the Workshop.
  2. Use T1–T5 buttons to show or hide tiers. Reset clears all numbers and restores the default visible tiers (T2–T5).
  3. The address bar updates with ?n= & h= & o= as you type. Copy the share link, or paste a full calculator URL to import your counts.
  4. Search by material name. Use the filter option to hide rows where still need is zero.

Craft-only materials

Some high-tier items cannot drop from stages; Still need counts the lower-tier mats you must craft first.

Pair with Material Usage

Use Material Usage Lookup to see which operators still consume a material you are farming.

Sample Farmable Materials

Drop rate labels (Always, Common, Rare, etc.) come from AN-EN-Tags game data. Higher tiers are usually craft-only.

Frequently Asked Questions – Arknights Material Farming

What are the best stages to farm materials in Arknights?

For general material farming: 1-7 (Orirock Cube), 6-11 (Sugar Pack), 9-4 (Integrated Device + Polyester Pack), 10-7 (Manganese Ore + Orirock Cluster). For LMD farm CE-5, and for EXP farm LS-5 or LS-6.

What is the most efficient way to farm T4 and T5 materials?

T4 and T5 materials cannot be farmed directly from stages — they must be crafted in the Workshop using T3 materials. The most efficient approach is to farm the corresponding T3 materials from their best stages and then craft upward.

Should I farm materials or buy them from the event shop?

Always prioritize buying T4 and T5 materials from event shops using event currency, as these are the hardest to obtain through normal farming. After exhausting the event shop, focus farming on T3 blue/purple materials you need most.

What stages drop both blue and purple materials?

Stage 9-4 drops both Integrated Device (T3) and Polyester Pack (T3). Stage 10-7 drops Manganese Ore (T3) and Orirock Cluster (T3). These dual-drop stages offer excellent overall sanity efficiency.

Is it better to farm or craft T3 materials from T1/T2 in Arknights?

For most materials, directly farming T3 blue materials from their best stages is more sanity-efficient than crafting up from T1 or T2. However, if you have an excess of T1 materials from early stages, crafting is a reasonable use of Workshop time.
