Zone Mundus defender Ideans

Replicard Sandbox > Zone Mundus, using defender encounters associated with the target element.

Before you go

Unlock Arcarum: The World Beyond and Replicard Sandbox.
Identify the element-specific Idean required by an Arcarum summon, Evoker, or weapon step.
Reach the relevant Zone Mundus area and have AP for its encounters.

Check the intended upgrade to confirm the target Idean and missing quantity.
Open Zone Mundus and inspect defender and related reward information for the target material.
Choose a defender route whose listed rewards fit the element or Idean family you need.
Defeat the available enemies along that route and collect battle rewards.
Check zone or chest rewards as they become available, then record the Ideans received.
Repeat the relevant defender activity while the target remains short.
Use the collected materials in the planned Arcarum or related progression step.

Do not assume every defender yields the same element; check the encounter’s reward details.
Keep the target tied to one upgrade so incidental drops do not pull you into unnecessary farming.

Repeat eligible defender encounters while the zone is available and you have AP; Idean and chest results are variable, not guaranteed per run.

Farming a defender before confirming its element: inspect its rewards against your target.
Counting possible chest contents as collected materials: verify inventory after each run.
Continuing after the upgrade requirement is covered: shift to the next missing material.

Stop when the intended summon, Evoker, or weapon requirement is met, or when another source better matches the remaining materials.
