Complete the first treasure quest in Legend of Defenders

Get the item the quest is asking for

1. Check that the current quest is asking for a Treasure.
2. Open the treasure interface and inspect the available purchases.
3. Choose an available treasure you can afford using the price and requirements currently shown.
4. Return to the quest and check its completion or collection state.

The actionable step is the treasure purchase. Continuing through more main-stage waves was not what the original player was missing.

Use the current price, not a launch-day table

The November 3 patch adjusted treasure prices and sorting. An old screenshot or an exact price copied from another guide may no longer describe your purchase screen.

This short route does not rank every treasure or prescribe a spending order. It resolves the acquisition step behind the quest. If your current requirement names a particular item, read that wording rather than treating any item as interchangeable.

Owning a treasure and opening its last slot are different tasks

If you already have treasures but the last Treasure Altar slot remains locked after Demon Tower level 5, follow the quest-chain check for that slot. Buying the first treasure does not establish every later deployment requirement.

Check the result

You should own the treasure and see whether the quest now allows completion or collection. If the item is present but the task has not changed, record the exact quest wording and item name before reporting it. Do not keep buying items based on an assumed price or an unverified quest sequence.
