NPC Name: N/A
Monster Name: Omega/Ultima
Steps:
1. We each obtained the appropriate Key Item to complete the Battlefield.
2. We teleported to Sealion Den.
3. We entered the Battlefield "One to be Feared" on Very Difficult setting.
4. We summoned trusts inside to fill out the party.
5. We defeated Omega followed by Ultima.
6. Upon coming out of the battlefield we received item and chapter drops but zero gear drops.

This happened to us twice in a row. We swapped to Difficult and received 2 gear item drops. My understanding was that at least 1 gear item drop was guaranteed on both Difficult and Very Difficult settings. Is this incorrect?

Thank you.

If it's an item that is "Rare" that everyone has and that same item is selected in that drop slot, then it will not load into the pool. That's normal, just as long as it's a rare item that not everyone has then it will load into the pool
