What the record establishes

The Horde record asks for six Cracked Sentry Cores from the City of Dalaran for Doctor Martin Felben in Undercity. Its description points to the city’s constructs; the rewards include Unstable Power Core and Construct Cloak.

Suggested approach

1. Confirm the accepted collection

   Verify the six-core objective and your version of the quest before entering. The dungeon category does not replace the faction and quest acceptance checks.

2. Inspect construct loot

   During relevant encounters, watch for Cracked Sentry Cores and personal progress. Notify the group when the collection remains short rather than assuming a completed dungeon guarantees six items.

3. Check the return inventory

   Confirm six credited cores before leaving, then plan the Undercity handover. At the reward choice, compare actual stats and slots with your current equipment.

Planning notes

The names create an easy inventory mistake: Cracked Sentry Cores are the requested items, while Unstable Power Core is a listed reward. Distinguish them before deleting or searching for an item. The return destination also matters when comparing a Dalaran quest bundle; several other records lead elsewhere.
