Summary: After saving Valbar, Kamui and Leon, Celica's crew will again have to go through more ships full of foes. This time, only a Cantor will be on the battlefield. However, as more turns it takes to defeat him, the more Revenants he'll summon to come to his aid. The Cantor will also regenerate 1 HP per turn, so defeating him as quickly as possible is a must.
After defeating the Cantor and all the summoned Revenants, you will actually go a miniature beast hunt for the Necrodragon. This dragon zombie can be a tough defeat, but there are a few things you can do to make for an easier win: raise Celica until she learns the skill of Seraphim, make sure Genny has learn Invoke by this point, and Valbar and his high Defense be at the front of your party. Defeating the Necrodragon will earn you the Blessed Ring
