Construct level and promotion
Advanced Promotion Materials
Target the exact advanced material needed for a mid-game promotion and avoid wasting Serum on unrelated drops.
WHERE & HOW TO FARM
Advanced Promotion Materials
Resource > Material, or a mid-game story stage whose reward preview lists the exact Advanced Promotion Material required by the Construct.
Before you go
- The Construct profile shows an Advanced Promotion Material requirement.
- The exact material name and remaining quantity are recorded.
- The matching Resource or story stage is unlocked.
Farming steps
- Open the Construct profile and inspect the next promotion tier’s item list and level gate.
- Write down the exact advanced material and the quantity still needed.
- Check Resource > Material stage previews for that specific item.
- Check available mid-game story reward previews for the same material, especially if continuing story progression.
- Choose a source that actually lists the item and that your team can clear reliably.
- Spend Serum until the profile shows the required quantity, then return to the promotion screen.
- Complete the promotion if all other gates are met; otherwise identify the next unmet requirement before farming again.
- Higher difficulty can provide better quantities or rarer versions, but only choose it if the reward preview matches and you can clear it.
- Event shops sometimes list advanced materials; treat them as an option only when current stock names the needed item.
Repeat, collect and use
Repeat the confirmed stage until the count for this promotion is met. Promotion itself is a one-time tier step; later tiers may require another material and need a fresh check.
Common mistakes
- Assuming one Advanced material works for every Construct; read the specific profile entry.
- Spending Serum on an unverified story stage; confirm the reward preview first.
- Farming beyond the required count when a level gate or another item is the real blocker.
When to stop or switch
Stop once the profile has enough material for the planned promotion, then switch to the remaining requirement or promote.
