Fish-like Phantom Monster's Relic
The relic of the Phantom Monster. May become useful if processed accordingly.

Can be dropped by the Pelagic Jester, Cetus, the new Phantom Beast that dwells in the Sea of Wonders just off of Alexandria. You will have to have beeaten him once to obtain the Cetus crest (which I currently can't find in the DB, oh well) before you have a chance at getting this item.

I expect the future Ultramarine Cetus upgraded boss from Chapter 3.5 will drop it even ore reliably, though we will see. That aside, this consumable is used with all the new Chapter 3: Cetus recipes from Ibn in Alexandria. Makes:

Flag of a Sea Monster
Sea Monster's Tusk
Phantom Paneling
Sea Monster's Hood
Sea Monster's Robe
Sea Monster's Evil Spear

All of those are Memorial Album items, and the equipable clothing/weapon have some nice stats indeed. More details to come in time. Feel free to contribute as well. Cheers.

Phantom Paneling
Sea Monster's Hood
Sea Dragon's Robe
Sea Monster's Evil Spear
Cetus (crest; no link right now)

It has been confirmed by GM that all of the above items crafted from Fish-like Phantom Monster's Relic are unplunderable. This does not extend to any of Ibn's other available recipes, including Hyper-series cannons.
