So let’s dive into… all of that.

After that, it’s just a long trek south down the river to reach the Cerulean Coast.

Use the large rocks as platforms until you reach the ground, then just keep charging south.

Just head directly south, killing or avoiding enemy threats as you see them.

Be patient, don’t get greedy, and you’ll finish him off.

When you attempt to head towards St. Trina’s cave, you’ll find the way blocked.

He’ll lament his weakness, and ask you to tell him what St. Trina said.

His summon sign will appear on the left just outside the fog wall of the final boss arena.

After that’s done, return to the Garden Of Deep Purple and proceed into St. Trina’s cave.
