Arcarum and Replicard Sandbox
Target a single tetra-element Idean
Focus Sandbox runs on the element-specific Idean that advances a chosen Arcarum upgrade.
WHERE & HOW TO FARM
Target a single tetra-element Idean
Replicard Sandbox > Here Be Swords or an appropriate Olden Primal Series area, using a five-gauge enemy whose preview lists the target Idean.
Before you go
- Unlock Replicard Sandbox and the relevant region.
- Name the element-specific Idean needed for your summon, Evoker, or weapon plan.
- Check the planned upgrade to determine how many are still missing.
Farming steps
- Open the target area and inspect the five-gauge enemy drop previews.
- Choose Here Be Swords when its pool matches the tetra-element Idean you need.
- If using Olden Primal Series, confirm the selected encounter lists the target element.
- Clear the chosen encounter and collect its rewards.
- Check the Idean count in your inventory after the run.
- Repeat the same encounter rather than rotating through unrelated pools.
- Apply the Ideans to the planned Arcarum progression when the requirement is met.
- Zone Mundus is a broader source, but its tetra-element results are split among elements.
- Keep light or dark materials only when they also match a progression requirement you are pursuing.
Repeat, collect and use
Repeat while the chosen node is available and the target count is short; Idean drops are variable.
Common mistakes
- Farming a broad pool for a specific element: choose a node whose preview includes the desired Idean.
- Mixing up the target element: check the upgrade requirement before committing AP.
- Ignoring inventory between runs: verify the count and stop when the target is met.
When to stop or switch
Stop as soon as the chosen summon, Evoker, or weapon requirement is covered; move to the next missing material in that upgrade.
