WHERE & HOW TO FARM Where to farm Replicard Sandbox > Here Be Swords or an appropriate Olden Primal Series area, using a five-gauge enemy whose preview lists the target Idean.
Ideans support Arcarum summon progression and related Evoker or weapon development. When you need one tetra-element Idean, choose a node with a concentrated drop pool instead of farming a broad area that divides its results among several elements.
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. 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. Farming tips 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.
