Resources and Currency Guide

Updated for 13 March 2024 patch.

Resource Location Guide

Here's a quick guide to where you can find the most common consumable resources:

ItemUseLocation

Gold
Levelling up units
Upgrading and refining gears
Purchasing ability pills

Note: gear refining is very gold intensive in the late game. You can never have too much gold.
Path of Adventure (recommended, uses Cooked Rice)
Daily dispatch ability
Last Night rewards
Story mode battles
Golden Thread Shop

Slimes
Levelling up units

Note: Prioritize farming slimes in the early game. Once you have your main team members at max level, switch to prioritizing gold farming.
Story mode battles
Path of Adventure (recommended, uses Cooked Rice)

Ability Pills
Used for all field abilities (e.g. Cooking, Search, etc).
Alchemy and Gear Crafting cost a lot of ability pills.
Purchase from any story mode shop
(Preferably after completing a daily quest for 10% discount)
Sylvia's Bargain does not work on Ability Pill prices.

Ability Books
Levelling up field abilities

Note: Prioritize levelling up Dispatch (Olstein and Diana), Alchemy (Schera) and Gear Crafting (Layla). Levelling up Search (Lathel) is convenient to have but not a must. Other than those skills, levelling up other skills are not a priority.

You get some free ability books from story mode achievements.
Devil Coin Shop (recommended)
Golden Thread Shop

Rank Up Stars
Levelling up units

Note: Level 4 Rank Up Stars are relatively hard to come by for beginners, so consider carefully who you want to use them on when starting out. You'll eventually have a surplus after maxing out your main characters, but it will take several months to get there.

You get some free Rank Up Stars (mostly Level 2 and Level 3) from story mode achievements and events.
Mirror Wars Shop
Evil Castle Shop
Golden Thread Shop
Powder of Hope Shop

3* R. Contracts
Recruiting from the pub (not the gacha banner)

Note: It is recommended that you do not recruit 3* units or 4* units in the pub, as you can easily get them to max level anyway. Instead, save them up to recruit 5* units in the pub.

In the main shop, 10x 3* contracts can be converted into a 4* contract, and 10x 4* contracts can be converted into a 5* contract.
(i.e. 100x 3* contracts = 1x 5* contract)

For beginners, this is a rare time-gated currency. However, once you have recruited all of the 5* units from the pub (which will take many months of play), you may start to build up a surplus.
Mirror Wars Shop
Evil Castle Shop
Ancient CrystalsNecessary for UR Gear crafting

This is a rare time-gated currency.
Evil Castle clear rewards
Evil Castle season rewards
Golden Thread Shop
Last Night rewards

Refining powder
Used for refining gear stats after the gear reaches +9.
Lowest gear refinement is C C C, highest is S S S. Gear refining costs a lot of refining powder, and you can never have enough.

Note: refinements only affect main stats, not sub-stats
Daily quests
Dismantling gears
Note: you can dismantle in bulk from the inventory menu

Refining stone

Refining crystal
Used for changing gear attributes (other than fixed attributes).
Refining stones are for N and R gears. Refining stones are not very useful, because N and R gears are not really worth refining.
Refining crystals are for SR and UR gears. Refining crystals can be farmed by dismantling SR gears, but it costs a lot of gold and crafting materials.
Dismantle N and R gears for refining stones.
Dismantle SR and UR gears for refining crystals.

Refining crystal also available in Mirror Wars shop.

Elemental Crystals
Used for enhancing a costume's potential. For more information on potential, check out this guide.

Elemental Crystals can be found in the Elemental Caves, which are accessed via the Path of Adventure Pack. This is a time-gated currency, because entry to the Elemental Caves costs torches, and you only get 60 free torches per day. There is a different color crystal for each element.

Once you have cleared an Elemental Cave in a chosen difficulty, you can auto-farm from the field menu (same as gold and slime farming with cooked rice).
Path of Adventure:
Cave of [Element]

Tear of the Goddess
Used for unlocking skill bonuses via the costume potential system.

This is an extremely rare and time-gated currency.
3 Tears are required to fully unlock the skill potential of a single costume, so they should be used very carefully.
Golden Thread Shop

Gold is used for crafting many UR gears

Copper and gold are rarer materials and tend to run out before other materials
Hunting Grounds (Lizardman Altar Very Hard is best)

Crafting material - WoodWood is used for crafting all level gears
