WHERE & HOW TO FARM
Narrow an artifact formula farm by its cost tier
A repeatable boss route on the difficulty eligible for the chosen Immortal Throne Arcane Formula; use the formula record to select the boss before traveling.
Before you go
- Own Immortal Throne and have access to an Enchanter.
- Identify the exact Arcane Formula you want and its creation cost.
- Verify the formula’s eligible difficulty and listed boss sources before choosing a route.
- Be able to clear the selected boss reliably and have inventory space for drops.
Farming steps
- Look up the exact Arcane Formula and note its listed creation cost and required reagents.
- Use the cost only as a clue to the formula’s tier; confirm the eligible difficulty and boss source in the item record.
- Select a listed boss whose route you can repeat on that difficulty.
- Travel to the boss, defeat it, and inspect its reward drops for the named formula.
- If the formula is absent, repeat the same eligible boss route rather than changing tiers based on cost alone.
- When the formula drops, collect the separate relic, charm, or other reagents specified by its recipe.
- Bring the formula and full reagent set to an Enchanter to create the artifact.
- Keep the exact formula name visible while checking drops; similar artifact names can have different ingredients and sources.
- Do not treat creation cost as a drop-rate estimate or guarantee. The boss table and eligible difficulty are the checks that determine the route.
Repeat, collect and use
Repeatable boss farming until the formula drops. The formula and its reagents are separate acquisitions, and no particular clear guarantees either one.
Common mistakes
- Choosing a boss tier from cost alone: confirm the formula’s eligible difficulty and source before farming.
- Expecting the artifact to drop fully assembled: obtain the formula and each listed reagent, then visit an Enchanter.
- Switching bosses after every unsuccessful clear without checking sources: repeat a boss that is actually listed for the target formula.
When to stop or switch
Stop farming bosses for the formula once it is in your inventory; switch to collecting only the missing recipe reagents, then craft at an Enchanter.
